At exactly 9AM on 16 August, a 4.5M earthquake hit Xizang on the Tibetan Plateau. Four hours later, 65km away in Nepal, <a href="https://nepalitimes.com/news/climate-breakdown-linked-to-thame-flood">a glacial lake burst</a> unleashing a cascade of destruction downstream. It is not certain if that tremor so nearby caused the lake to burst — either because an avalanche on the south ridge of Mt Tengi Ragi Tau fell into it, or heavy monsoon rain led to the collapse of a moraine. Either way, the snowmelt emptied into another lake below and unleashed a debris flow that roared down the valley to the village of Thame. Fortunately, children at a school had gone home early that Friday and inhabitants had time to climb to safety when they heard the approaching roar. There were no fatalities. Thame was not as lucky on 4 August 1985, when a bigger lake in an adjacent valley, <a href="https://nepalitimes.com/here-now/nepal-s-mountains-are-melting">Dig Tso, burst after an avalanche fell on it</a>. Twelve people were swept away by the ensuing flood, a newly built hydropower plant was destroyed, and a section of the Everest trekking trail was washed away.&nbsp; <a href="https://nepalitimes.com/news/climactic-change">Glaciologist Tenzing Chogyal Sherpa</a> remembers his mother telling him that their home in Namche Bazaar was spared because it was on higher ground. “But she told us that with trails destroyed, food and supplies couldn’t reach us. At one point, her family had to survive on rotten potatoes,” recalls Sherpa, who works at the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD) and uses remote sensing to map climate-induced hazards in the Himalaya. &nbsp; He says the Thame flood this week was a reminder of the inherent risk of living in the mountains which are magnified by climate breakdown. And the region is still very much at risk.&nbsp; “To the south, we have Lumding Tso, a potentially dangerous glacial lake that also empties into the Dudh Kosi, and <a href="https://nepalitimes.com/banner/human-face-of-a-himalayan-climate-crisis">to the west in Rolwaling is Tso Rolpa</a>, a lake that is now 3km long. And to the north is Dig Tsho, which burst in 1985,” says Sherpa.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240823050844_34eedc4fb5b287a3b861a2b2196758c635d011ec5666bac2031a8c6f0bde801b.jpg" data-media-id="editor_4" data-image-id="20240823050844_34eedc4fb5b287a3b861a2b2196758c635d011ec5666bac2031a8c6f0bde801b" data-rendition-name="original" width="623" height="695" loading="lazy" alt="Thame flood map"> </figure>  "We are facing one of the worst disasters since the Dig Tso flood.

The Thame flood was a smaller disaster compared to the flood that <a href="https://nepalitimes.com/banner/climate-smarter-himalayan-infrastructure">destroyed the Melamchi headworks in 2021</a>, the <a href="https://nepalitimes.com/news/sikkim-flood-is-warning-to-nepal">massive Sikkim flood last year</a>, or the <a href="https://nepalitimes.com/here-now/what-is-lost-cannot-be-repaid">debris flow that ravaged Kagbeni</a>. All were caused by glacial lake bursts or moraine collapses due to extreme rainfall. Anil Pokhrel of the National Disaster Risk Reduction and Management Authority (NDRRMA) flew to Thame on Saturday morning to inspect the glaciers above the village. He confirmed that two of five small glacial lakes below Tashi Lapcha pass had caused the flood. Satellite data shows that till two years ago, there were only four lakes.&nbsp; Across the Himalaya, there are now thousands of new glacial lakes that <a href="https://archive.nepalitimes.com/article/nation/Lake,1404">do not even have names</a>. In Nepal most of the <a href="https://nepalitimes.com/here-now/danger-nepal-s-glacial-lakes-are-filling-up">21 most dangerous ones</a> are located in the centre and east of the country, but there are dozens of enlarged lakes in China which drain into tributaries of rivers that flow into Nepal like the two Bhote Kosis, Arun and Tama Kosi.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240823050844_4e2cc8d68aea97f2b8262553ada6d911acf0ff1883b5454b151e85effde1745e.jpg" data-media-id="editor_11" data-image-id="20240823050844_4e2cc8d68aea97f2b8262553ada6d911acf0ff1883b5454b151e85effde1745e" data-rendition-name="original" width="920" height="496" loading="lazy" alt="at risk GLOFs in Nepal map"> </figure>  Some of these lakes are infamous because of their volume, the rate at which they are expanding, and the potential danger they pose to populations downstream — like Tso Rolpa, <a href="https://nepalitimes.com/banner/walking-the-talk-on-climate">Imja Tso</a> and Thulagi. But the Thame flood, and others like the Nare Lake outburst below <a href="https://nepalitimes.com/banner/what-is-it-about-ama-dablam">Ama Dablam</a> in 1977 show that even smaller lakes can cause massive damage. In fact, it does not even take a lake burst to cause destructive debris flows. The Melamchi and Kagbeni floods appear to have been caused by moraines that collapsed in unusually heavy rain because they were no longer cemented by permafrost.&nbsp; Even a relatively small flood like the one in Thame can be damaging far downstream. The debris flow moved swiftly downstream, destroying a Rs80 million bridge on the Dudh Kosi in Okhaldhunga. Most villages downstream had been evacuated, so there were no casualties. If the flood had been bigger, it would have threatened <a href="https://nepalitimes.com/multimedia/missing-pieces-of-the-hydropower-jigsaw">major hydropower projects</a> on the Dudh Kosi. “We cannot ignore smaller lakes anymore,” warns Pokhrel of NDRRMA. “We often think and plan from a hazard perspective, how big a disaster can be. But we must also look at risk, possible cascade damage on downstream communities.”&nbsp; Thame is at 3,840m elevation, but Pokhrel says he was surprised by how warm it was up there this week. “It felt like Kathmandu,” he says. “And satellite imagery shows accelerated melting of the upstream in the past month which could have led to the cascading collapse of the two lakes.”&nbsp; Glacial lake outbursts and debris flows are going to be more destructive and frequent in Nepal in the coming years, making them a fact of life. Seismic risk in the Himalaya adds to the dangers posed by the climate emergency. Local communities and governments have no option but to adapt by installing early warning systems, planning <a href="https://nepalitimes.com/here-now/what-s-cooking-in-nepal-besides-politics">smaller decentralised hydropower schemes</a>, moving settlements and infrastructure higher, and conducting detailed hazard mapping. “Thame showed us we cannot only rely on satellite mapping, and why in-situ observation is so important in a country with such a diverse topography and climate as ours,” says Sherpa. “There are more than 50,000 glaciers in the Himalayan region and we haven’t even studied 1% of them.”  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2024082108084_aa61ab79fcc840b34f0392965affa0dbe6ad7c86f99c8b0205b0ce49c9584c64.jpg" data-media-id="editor_16" data-image-id="2024082108084_aa61ab79fcc840b34f0392965affa0dbe6ad7c86f99c8b0205b0ce49c9584c64" data-rendition-name="original" width="1500" height="1000" loading="lazy" alt="thame flood"> <figcaption>Thame flood this week. Photos: RSS</figcaption> </figure>  Despite the scarcity of field data, there have been considerable advances in remote sensing technologies that have helped fill this gap in data and help understand the changing cryosphere. ICIMOD’s recent report shows that glacier mass loss has increased by 65% in recent decades. The report also warns that the risk of flooding could increase much more in the coming century. Because so many of Nepal’s rivers are transboundary, a bilateral early warning mechanism with China is also urgent. Because of the scale of the danger, Nepal needs resources from the international community for adaptation, as well as <a href="https://nepalitimes.com/news/lost-and-damaged">loss and damage reparation</a> to cope with future risk. “Our government needs to get in touch with the Chinese government to conduct a study of glacier lakes located near Tibet, which are the source of glaciers in Nepal. We should collaborate on early warning system and implementing risk reduction measures,” says Anil Pokhrel.&nbsp; Tenzing Chogyal Sherpa co-founded a global advocacy campaign called <a href="https://saveoursnow.earth/">#SaveOurSnow</a> last year to provide local communities with agency to deal with climate induced risk. Supporters of the campaign include former new Zealand Prime Minister Helen Clark, celebrity mountaineers like Reinhold Messner, Chris Bonington, Kenton Cool and the descendants of Tenzing Norgay. Says Sherpa: “As glaciers melt and lakes expand, disasters like Thame will be more frequent, we have to adapt. We need to tell our stories to the world, even as they continue to debate on the topic, we are already facing the brunt of it without having caused it ourselves. At local levels, we have to get back on our feet and prepare for what's coming.”&nbsp;

Lives on the line in the Himalaya

Some 15 million people worldwide are at risk from flooding caused by glacial lakes, half of them in India, China, Pakistan and Peru, according to the latest study published in the journal Nature Communications. As the most densely populated mountain country in the world, Nepal is at higher risk. Glacial Lake Outburst Floods (GLOFs) in the Nepal Himalaya can be even more catastrophic for towns along valley floors as well as downstream infrastructure. <a href="https://www.nepalitimes.com/banner/climate-smarter-himalayan-infrastructure">What happened in Melamchi </a>in July 2021 is a sign of things to come. Nepal’s largest infrastructure project to supply water to Kathmandu was nearly destroyed by a massive debris flow after a cloudburst upstream in the Langtang National Park. “What make GLOFs worse in Nepal is that they are often combined with the monsoon,” explains watershed expert Madhukar Upadhyay. “Every year we have seasonal floods. When a weakened moraine is breached, more water is added to already swollen rivers. Making matters worse is high-intensity rainfall in higher altitudes as we saw in Manang in 2022.”&nbsp; Read more: <a href="https://www.nepalitimes.com/opinion/climate-risk-to-hydropower-investment/">Climate risk to hydropower investment</a>, Ajaya Dixit  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20230602040624_e60a90be970842d53f6e236b1a59612c82aa035635a3ae4838481a31710f1446.jpg" data-media-id="editor_2" data-image-id="20230602040624_e60a90be970842d53f6e236b1a59612c82aa035635a3ae4838481a31710f1446" data-rendition-name="original" width="853" height="640" loading="lazy" alt="Melamchi amage NT"> <figcaption>The damage from a massive debris flow on the Melamchi River in June 2021 to the channel diverting water from the Melamchi to the tunnel at the project headwork.

Tso Rolpa glacial lake at 4,580m in the Rolwaling Valley has grown seven times in size in the past 60 years. “There is a lot of evidence that the number of glacier lakes in Nepal and worldwide is increasing,” says Miriam Jackson, glaciologist with the International Centre for Integrated Mountain Development (ICIMOD). “The size of existing lakes is also increasing. For example, the area of glacier lakes increased by 12% in the Kosi basin and 8% in the Gandaki basin.” The water level in Imja has been lowered by 3.4m and by 3m in Tso Rolpa at a cost of $7.2 million and $9 million respectively. Scientists now say the water level in Tso Rolpa needs to go down by another 20m to reduce risk of bursting.

Photo: SHARAD JOSHI</figcaption> </figure>  There are other potentially dangerous lakes like Thulagi below Himalchuli, and new lakes are emerging on both sides of the Himalaya in China and Nepal that have not even been mapped. Nepal’s glaciers are shrinking three times faster than in 1998 and Jackson says that the possibility of flooding, whether from glacial lakes or other sources, is taken into account when building close to the rivers. When Nepal’s only reservoir project on the Kulekhani was commissioned in 1982, engineers had designed it to function for 100 years. But a cloudburst in the catchment area in 1993 deposited so much debris into the lake that its lifespan was reduced by 30 years. “Melamchi and Kulekhani are proof that the entire Himalayan region including Nepal are not suited for mega projects. Our focus and investment should instead be on multiple small-scale projects spread out across the country,” says watershed expert Madhukar Upadhyay. As for infrastructure already under construction, there are several mitigating measures that can be deployed, such as early warning and real-time information systems in the catchment area, not only about rainfall but GLOFs and landslide blocked rivers. Experts say Nepal and the countries in the Himalaya should not overlook the phenomenon of permafrost melting that is making the mountains and moraines much more prone to erosion. Permafrost is a thick subsurface layer of frozen soil that is generally not visible and thus harder to identify. Besides Melamchi, thawing permafrost is thought to have been partly responsible for the Chamoli disaster in the Indian Himalaya in 2021. Read also: <a href="http://archive.nepalitimes.com/news.php?id=2391#.XoyO8MgzbIU">The day after tomorrow in the Himalaya</a>, Navin Singh Khadka “Generally, moraines have an ice core, which is one reason why moraine-dammed lakes are so dangerous. The ice could be hundreds or even thousands of years old and melt very slowly but the moraine is constantly settling,” explains Jackson. “Thawing permafrost makes mountains unstable, thus causing rockfalls. If there is a landslide into a glacier lake, then that could trigger a flood.” GLOFs also have a transboundary dimension since so many of Nepal’s rivers and their tributaries originate in glaciers in Tibet. Of the 47 high-risk glacial lakes in Nepal, 20 of them start in Tibet (see map, below). Mitigating measures such as artificially lowering the water level are expensive which makes cross-border early warning of GLOFs so crucial. ICIMOD has launched the Kosi Initiative with a transboundary working group collaborating with the Chengdu-based Institute of Mountain Hazards and Environment (IMHE) and others. It has also done computer modelling of flood hazard and an assessment called WeACT that integrates local knowledge with science to improve community preparedness. But GLOF risk can be reduced if vulnerable communities are aware of the danger, are given decision-making powers and have the resources to be prepared, as has been seen in Chunkung in Khumbu and Langtang, where villagers are adapting to climate change by building embankments on their own, and avoiding construction along river banks. Says Madhukar Upadhyay: “We need to strengthen our local science to better understand the geology and glaciology, make local communities and the national government aware of the dangers and take the risk into account in building settlements, hydropower plants, bridges and roads.” &nbsp; Read also: <a href="https://www.nepalitimes.com/banner/human-face-of-a-himalayan-climate-crisis/">Human face of a Himalayan climate crisis</a>, Rastraraj Bhandari

For destruction, ice is also great and will suffice

Photo: SHARAD JOSHI</figcaption></figure>It is now looking doubtful if countries around the world can cut their greenhouse gas emissions as agreed in Paris six years ago, so that global temperature rise will be limited to 1.5 Celsius by 2050. The earth is going to heat up by more than that.Even if it is 1.5 Celsius, the average temperature in the Himalaya will go up by 1.8 degrees because of a phenomenon called ‘altitude effect’. The best-case scenario is that one-third of all remaining Himalayan glaciers will have melted during this century. However, if greenhouse gas emissions continue to rise at the present rate, two-thirds of Himalayan ice will be gone by 2100.All this will have a catastrophic effect on water supply for 1 billion people downstream on rivers that originate in the Himalaya, as well as throw off kilter weather systems.  It will also increase the danger of <a href="https://www.nepalitimes.com/here-now/nepals-glacial-lakes-in-danger-of-bursting/" target="_blank" rel="noopener noreferrer">glacial lake outburst floods</a> (GLOF) within Nepal.Till the 1960s, the Imja Glacier near Mt Everest had only a few melt-pools. Since then, the ice has been replaced by a lake nearly 2km long, 600m wide and up to 150m deep. The ice is receding 70m a year.As glacial lakes expand, there is a danger of them bursting due to water pressure, or because of earthquakes and avalanches falling into them. As the average temperature in the mountains rises by 0.056 Celsius every year, the threat of glacial lake outbursts will only grow.On top of the perennial risk of earthquakes, new hydropower stations, highways along rivers, bridges and towns will also have to take into account the threat of GLOFs. The flash flood near <a href="https://www.nepalitimes.com/latest/non-climate-cause-of-nanda-devi-flood/" target="_blank" rel="noopener noreferrer">Nanda Devi in India’s Uttarakhand state</a> in March washed away two hydroelectric plants that were under construction.There is a warning there for Nepal, which is building cascade projects on the two Bhote Kosi rivers that flow down from China, Tama Kosi, Marsyangdi, and the Arun. In the Gandaki Basin is the particularly dangerous Thulagi glacial lake below Himalchuli, which would directly threaten three major hydroelectric projects along the Marsyangdi River. Scientists monitoring Thulagi have found the glacier has receded by 2km since 1984, the ice replaced by a lake.<a href="https://www.nepalitimes.com/banner/tracing-past-glacial-floods-in-kangchenjunga/">Tracing past glacial floods in Kanchanjunga</a>, Alton C Byers<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109111140/636b83dc9c7e80680e06775fjpeg.jpg" alt="" width="1500" height="1080"><figcaption> </figcaption></figure>“If Thulagi were to burst, the flood would go down 100km downstream on the Marsyangdi and Narayani, taking out hydroelectric projects, highways and towns along the way,” says Pradeep Mool, a glacial scientist formerly with ICIMOD.A survey last year showed that GLOF risk is highest in eastern Nepal. There are 42 dangerous lakes on the Kosi basin alone, like Imja, Tso Rolpa, Lower Barun and Hongu. The bursting of any one of these would send a wall of water and debris downstream to the Kosi.There is also the danger of <a href="https://www.nepalitimes.com/editorial/more-himalayan-tsunamis/" target="_blank" rel="noopener noreferrer">transboundary GLOFs</a>. In the past, even the bursting of relatively small glacial lakes in Tibet have caused major damage in Nepal. The earliest recorded one was in 1934, when a flash flood from a glacial lake burst in Tibet caused destruction along the Bhote Kosi.In 1981, another glacial lake burst in China caused a flood on the same river in Nepal, damaging the Sun Kosi power plant and washing out a 25km section of the Arniko Highway, cutting Nepal’s only road to China for three years.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109111140/636b83e09c7e80680e067760jpeg.jpg" alt="" width="1000" height="1506"><figcaption> </figcaption></figure>Of the 47 very dangerous lakes that threaten Nepal’s valleys, 25 originate in glaciers in Tibet. Since 1977, there have been at least 20 GLOFs of which 14 were caused by glacial lakes in Nepal bursting, and the rest were in China.To understand what a GLOF looks like, we have the<a href="http://archive.nepalitimes.com/article/nation/Anatom-of-a-Himalayan-tsunami,1330" target="_blank" rel="noopener noreferrer"> Seti flood of 2012</a> which killed nearly 70 people north of Pokhara. Although not caused by a glacial lake burst, it demonstrated the destructive power of such a flood.Although Nepalis may not be responsible for global heating, it does not mean we can sit back and do nothing. While scientists try to figure out exactly how fast the glaciers are melting, Nepal’s policy-makers need to start planning to be prepared for floods that are bound to be unleashed.The danger of GLOFs are compounded by Nepal also being on a seismically active zone. Many of these fragile Himalayan glacial lakes could burst simultaneously during a large earthquake.<img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221109111140/636b83e39c7e80680e067761jpeg.jpg" alt="" width="1369" height="630">This calls for hazard mapping, early warning systems through SMS or radio, as well as mitigation efforts like those carried out to <a href="https://archive.nepalitimes.com/article/from-nepali-press/Diverting-danger,3172" target="_blank" rel="noopener noreferrer">reduce water levels on Imja</a> and Tso Rolpa. The microhydro scheme on the Langtang Lirung Glacier that reduces the water level on a recently-formed glacial lake, and also generates electricity could be a model for other remote valleys in Nepal.Because glacial lakes are located at such high altitudes in remote roadless areas, lowering their water level can be expensive. Most of the equipment has to be flown in by helicopter, and work is often hampered by altitude and weather. The question is: who should pay for these risk-reduction measures?“Even if the water level is reduced they can burst and come down like tsunamis, we have to keep monitoring the lakes, and install effective early warning systems in Tso Rolpa and Imja to at least save lives if we cannot save the infrastructure,” says Sarju Baidya of the Department of Hydrology and Meteorology.There are no feasible methods to prevent a glacial lake from bursting, and it is not in our power to stop the lakes expanding. So the only thing Nepal can do is to reduce the level of the most dangerous lakes, design downstream infrastructure taking the dangers into account, and to have an early warning system.Says Pradeep Mool: “What we can do immediately is to install measurement stations and monitor them by satellite, prioritise the high-risk lakes for site inspections to gauge the strength of the moraines, and make a short list of the most dangerous ones for early warning, and mitigation measures.”Read also: <a href="https://www.nepalitimes.com/banner/human-face-of-a-himalayan-climate-crisis/">Human face of a Himalayan climate crisis</a>, Rastraraj Bhandari

The etymology of the word itself shows that human dwellers of the Himalaya have known of the phenomenon for thousands of years, he says.“Even if these floods are not directly caused by climate change, it can exacerbate the disaster because of extreme weather events,” Gyawali said in an interview.Himalayan floods therefore pre-date climate change, and are caused by the vulnerability of these young, fragile mountains to natural and human-induced processes like the indiscriminate use of heavy earth-moving vehicles on poorly-engineered roads.  Such ‘bulldozer terrorism’, has exacerbated the frequency of landslides in central Nepal  after the 2015 earthquake, according to a recently published paper in the journal, <a href="https://www.sciencedirect.com/science/article/pii/S2590061721000193" data-saferedirecturl="https://www.google.com/url?q=https://www.sciencedirect.com/science/article/pii/S2590061721000193&amp;source=gmail&amp;ust=1615627463313000&amp;usg=AFQjCNFfGOeUwHuVmX29jd0yc9zjQ9LTRg">Progress in Disaster Science.</a> <figure><img width="499" height="397" src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111152/636cd85d9c7e80680e092e3bjpeg.jpg" alt=""><figcaption> </figcaption></figure>After analysing remote sensing data, the researchers conclude that although the number of landslides had started falling after 2015, there has been an uptick since 2017 possibly due to the <a href="https://www.nepalitimes.com/opinion/dozers-and-nepals-development/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/opinion/dozers-and-nepals-development/&amp;source=gmail&amp;ust=1615627463313000&amp;usg=AFQjCNEh-pzzDl7j405T7swUxTKR34tVPg">proliferation of rural road construction</a> around the time of the elections. (See graph, above.) Gyawali suggests that a solution could be better-planned infrastructure and settlements that take into account known hazards. As the Chamoli flood showed, expensive hydroelectric projects located closer to the high mountains are more at risk. He suggests investing in smaller hydropower plants in side tributaries rather than the main stem of major Himalayan rivers to mitigate the danger, and to spread the risk. However, most of Nepal’s planned large hydropower projects are on rivers like the Tamor, Arun, Dudh Kosi, Bhote Kosi and Budi Gandaki. The Himalaya is a young and unstable mountain range that is battered by a heavy monsoon three months a year. Into this high-risk zone, there is now the added threat of climate-induced disasters. Says Gyawali: “We cannot completely remove these disasters from happening, but we can try to understand them and plan to minimise the risk.”

Non-climate cause of Nanda Devi flood

A <a href="https://www.planet.com/" target="_blank" rel="noopener noreferrer">PlanetLabs</a> image seems to confirm that a rock-ice slope detached completely from near the summit of the 7,816m high peak in the Garhwal Himalaya near Nepal’s western border, crashed on to the glacier below, and bulldozed the ice and debris into the Dhauliganga and the Alkananda Rivers.
There are tell-tale signs of new brown dust on the western side of the valley in satellite images. The ice melted as it reached a warmer, lower altitude and unleashed the flood that raced downstream. Two hydroelectric projects on the rivers were completely destroyed, highways were washed away and settlements buried under metres of water and debris. 
The Nanda Devi disaster is almost identical to the <a href="http://archive.nepalitimes.com/article/nation/Anatom-of-a-Himalayan-tsunami,1330" target="_blank" rel="noopener noreferrer">Seti River flash flood</a> of 2012 north of Pokhara that killed nearly 80 people. A massive chunk of rock near the summit of Annapurna IV broke off, fell on the glacier and the ensuing flood <a href="http://archive.nepalitimes.com/news.php?id=19479#.YCEipy8RoWo" target="_blank" rel="noopener noreferrer">barrelled down the Set</a>i, causing the fatalities.
Another <a href="https://nepalitimes.atavist.com/high-water" target="_blank" rel="noopener noreferrer">flash flood on the Arun River</a> in eastern Nepal in 2017 was traced to slope failure on a mountain on the Nepal-China border that fell on a glacial lake, triggering a flash flood that washed down so much debris that it dammed the main river.
In all three cases, disasters that at first thought to be a Glacial Lake Outburst Floods (GLOF) turned out to be rock-ice avalanches that led to a glacier collapse. The water and debris then cascaded down the valleys in a deadly paste obliterating everything in its path.
Whereas the increased risk of GLOFs in the Himalaya is linked directly to the climate crisis melting the ice and expanding moraine-impounded lakes, this does not appear to be the direct cause of the Nanda Devi event—just as it was not in the Seti and Arun. Rockfalls that lead to the collapse of glaciers, squeezing the water out of ponds in them and melting of the ice as it is pushed down to a warmer altitude.
Some of these glaciers may have lakes that top over when an avalanche or rockfall hit their surface, or global warming may have melted the ice within debris-covered glaciers. We do not know if these events are becoming more frequent due to a Himalayan thaw caused by the climate crisis.
Whatever the case, it is clear that the countries that share the Himalaya from Afghanistan to Burma have to be prepared for more frequent disasters of this type. The risk of GLOFs and flash floods have to be <a href="https://www.nepalitimes.com/banner/human-face-of-a-himalayan-climate-crisis/" target="_blank" rel="noopener noreferrer">factored into planning infrastructure</a> and human settlements downstream.
Although GLOFs and glacial collapse get all the attention, the Himalaya are also prone to landslide-blocked dams during the rainy season. The mountains are relatively young, they are seismically active and their slopes very unstable. Monsoon rains have been known to trigger landslides the block major rivers, as happened on the Bhote Kosi in Jure in 2014.
Fortunately, the river found a way around the blockage. But there have been cases when the impounded lake is large enough to cause catastrophic bishyari floods downstream when the landslide dams collapse.
The flat terraces where the city of Pokhara is situated today was probably formed, geologists say, when a landslide blocked the Seti upstream some 700 years ago. It gave way, <a href="http://archive.nepalitimes.com/blogs/kundadixit/2012/05/05/avalanche-flood-on-seti/" target="_blank" rel="noopener noreferrer">unleashing a tsunami</a> at least 150m high. Pokhara is located in the debris fan of this flood which dammed side rivers, forming Phewa, Begnas and other lakes.
To warn that <a href="https://www.nepalitimes.com/banner/tracing-past-glacial-floods-in-kangchenjunga/" target="_blank" rel="noopener noreferrer">similar catastrophes can strike</a> in the Himalaya is not panic-mongering. It is a call to be prepared. And let us hope the worst-case scenario of a mega-quake causing multiple glacial lake outburst floods does not happen any time soon.A Himalayan <a href="https://www.nepalitimes.com/here-now/nepals-glacial-lakes-in-danger-of-bursting/" target="_blank" rel="noopener noreferrer">Glacial Lake Inventory</a> launched at a <a href="https://www.icimod.org/event/glacial-lake-inventory-launch/" target="_blank" rel="noopener noreferrer">webinar</a> on Monday says that of the expanding glacial lakes in the Himalaya, 47 on the watersheds of Nepal’s three main rivers are at high risk of bursting, and causing catastrophic floods downstream. Of these, 42 lakes are on the Kosi River basin in eastern Nepal, three are on the Gandaki and two on the Karnali watersheds.A report last year by the <a href="https://www.icimod.org/event/glacial-lake-inventory-launch/" target="_blank" rel="noopener noreferrer">International Centre for Integrated Mountain Development (ICIMOD)</a> and UNDP mapped 3,624 glacial lakes in the Kosi, Gandaki and Karnali basins and found 47 lakes at risk from bursting. Of these 25 are in Tibet and drain into rivers that flow into Nepal. For now, existing towns along the rivers must have early warning systems. Infrastructure planning must take into account the glacial flood risk. And because so many of the high-risk glacier-fed rivers flow across national boundaries, international cooperation must be a must.

For example, remote sensing data in the report showed that there were 3,609 glacial lakes in Nepal’s three river basins with a combined area of 180sq km. By 2015, the number had grown to 3,696 and they covered a combined area of 195.4sq km.Scientists have long noted that the rate of melting is higher in the eastern Himalaya than in the west, and the report confirms this. Interestingly, while the number of glacial lakes in the Kosi basin has gone down, their total area has increased by 14sq km – largely because supraglacial ponds have merged, or the lakes have drained without bursting.The report has also recorded 26 <a href="https://nepalitimes.atavist.com/high-water" data-saferedirecturl="https://www.google.com/url?q=https://nepalitimes.atavist.com/high-water&amp;source=gmail&amp;ust=1599636709453000&amp;usg=AFQjCNG57P3tY-Tj18gLSJl0V0eJT_JiAg">glacial lake outburst flood (GLOF) events</a> in the Nepal Himalaya since 1977, but only 14 of them were on lakes located in Nepal. This emphasises the importance of trans-boundary early warning system – especially on lakes in Tibet upstream on the two Bhote Kosi rivers, Tama Kosi, the Arun and others.

The newly-formed Himalayan Art Council is set to launch Nepal’s National Art Protection Platform that seeks to preserve <a href="https://nepalitimes.com/banner/the-history-of-heritage">Nepal’s unique cultural heritage </a>using<a href="https://nepalitimes.com/here-now/artificial-censorship"> AI-powered tools</a>. The Council seeks to safeguard <a href="https://nepalitimes.com/banner/nepali-art-going-places">Nepali art works</a> from neglect, theft and counterfeiting as well as preserve existing artwork and celebrate living masters by giving them a cultural space to continue the <a href="https://nepalitimes.com/banner/sacred-survival">sacred art traditions</a>. "We are introducing a new digital platform designed to preserve, verify and elevate <a href="https://nepalitimes.com/banner/nepals-new-generation-of-alternative-artists">Nepal’s art for generations to come,</a>” says a statement from the Council, adding that the digital platform will use AI told for authentication and blockchain to keep track of works of art. Artists can now be protected by <a href="https://nepalitimes.com/multimedia/ayo-ai?fbclid=IwAR1uwmTVq4gUB70ljfRezjzukD9ArWXPuMnUikopeQ8PoiZMjicToPSwhKE&amp;=1">AI tools</a> that detect forgeries, identify their work even when unsigned, and ensure they receive proper recognition and credit. The archives will be searchable with translated inscription and interactive guides. Says curator Meena Lama: “AI and blockchains are tools that give us the power to detect fakes and identify unsigned paintings and track every piece. With these tools we can restore trust, secure authorship and give artists the dignity they deserve.”  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250514170544_2ab58f6313c0458f75114a692b0016bd9efb3b59d5f8f07f0da72e1e37b82f53.jpg" data-media-id="editor_6" data-image-id="20250514170544_2ab58f6313c0458f75114a692b0016bd9efb3b59d5f8f07f0da72e1e37b82f53" data-rendition-name="original" width="1300" height="1000" loading="lazy" alt="Artwork at the Traditional Art Exhibition at Patan Museum."> <figcaption>Artwork at the Traditional Art Exhibition at Patan Museum.</figcaption> </figure>  The Council is also holding an exhibition of Nepali cultural masterpieces with 50 historical <a href="https://archive.nepalitimes.com/article/Nepali-Times-Buzz/Buzz-the-art,671">thangka and paubha </a>by past masters and <a href="https://nepalitimes.com/review/between-the-sacred-and-everyday">contemporary works by current artists</a>.

Digital protection for Nepal’s art

India and Pakistan are twins separated at birth. Tensions between them have been at a hair trigger ever since independence and has erupted into full scale conflict at least four times in the past 80 years.
The 22 April terrorist attack in Kashmir that killed 25 Indian tourists and a Nepali citizen, threatens to escalate tension between the two nuclear-armed nations. India has squarely blamed Pakistan for the attacks, and Prime Minister Narendra Modi has given his military “operational freedom” to respond. Pakistan has said it has credible intelligence of an Indian military strike and its officials have promised a “full spectrum” response — a code for a <a href="https://nepalitimes.com/editorial/thinking-the-thinkable">nuclear retaliation</a>.
For Nepal, the killing of its national in the Pahalgam attack comes as another stark reminder that in conflicts from Afghanistan to Iraq, from <a href="https://nepalitimes.com/opinion/how-to-agree-an-armistice-in-ukraine">Ukraine</a> to Israel, <a href="https://nepalitimes.com/news/10-nepalis-from-one-town-fighting-in-ukraine">Nepalis are getting caught in the crossfire</a>. The last time full-scale fighting broke out between <a href="https://nepalitimes.com/opinion/peacemongers-at-india-pakistan-border">India and Pakistan</a> on Kargil in 1999, at least 22<a href="https://nepalitimes.com/here-now/india-s-trial-by-fire-for-soldiers-from-nepal?%27%5C%22="> Nepalis fighting for the Indian Army</a> were killed in action.
Three of Nepal’s immediate neighbours (China, India, Pakistan) have nuclear weapons, and they do not have good relations. With China supplying weapons, <a href="https://nepalitimes.com/editorial/war-and-warming">missile technology</a> and other support to Pakistan, this triangular friction could set off a regional conflagration.&nbsp;
<a href="https://www.nature.com/articles/s43016-022-00573-0" target="_blank">Research at Rutgers University</a> has calculated that even a week-long tactical nuclear exchange between India and Pakistan would throw up so much smoke and debris into the atmosphere that it would block out the sun for years, and lead to a collapse of the <a href="https://nepalitimes.com/news/grow-nourish-sustain-together-world-food-day">global food system</a>. This does not take into account the radioactive fallout that prevailing winds would blow up to <a href="https://nepalitimes.com/here-now/lives-on-the-line-in-the-himalaya">the Himalaya</a>, contaminating glaciers that are the sources of <a href="https://nepalitimes.com/here-now/saving-what-is-left-of-himalayan-rivers">Asia’s main rivers</a>.
The impact of <a href="https://nepalitimes.com/news/climate-breakdown-linked-to-thame-flood">climate breakdown </a>on High Asia was already ringing alarm bells about its <a href="https://nepalitimes.com/news/himalayan-icecap-melting-faster-than-thought">shrinking ice cap</a> reducing the dry season flow of water downstream. Water was going to be the next strategic commodity, geopolitical experts warned, and the next wars in Asia would be over water.
That water war is already happening. India retaliated to the Kashmir attack by suspending the <a href="https://www.nytimes.com/2025/04/24/world/asia/india-pakistan-indus-waters-treaty.html" target="_blank">Indus Waters Treaty</a> of 1960 mediated by the World Bank that has withstood at least three wars between India and Pakistan. The treaty gives India control over the three eastern tributaries of the Indus (<a href="https://en.wikipedia.org/wiki/Beas_River" target="_blank">Beas</a>, <a href="https://en.wikipedia.org/wiki/Ravi_River" target="_blank">Ravi</a> and <a href="https://en.wikipedia.org/wiki/Sutlej" target="_blank">Sutlej</a>), while Pakistan got water from the Indus and two of its western tributaries (<a href="https://en.wikipedia.org/wiki/Indus_River" target="_blank">Indus</a>, <a href="https://en.wikipedia.org/wiki/Chenab_River" target="_blank">Chenab</a> and <a href="https://en.wikipedia.org/wiki/Jhelum_River" target="_blank">Jhelum</a>.
Pakistan was assured of 70% of the annual flow, and India could use a reasonable amount of water for<a href="https://archive.nepalitimes.com/news.php?id=15231"> irrigation and hydropower</a>. &nbsp;Within days of its threat, India stopped water flowing down to Pakistan from the Chenab river and is reportedly preparing to do the same on the Jhelum.
The sabre-rattling has reached a crescendo. Besides threats and counter-threats there are also symbolic drills, with the Indian Air Force practicing landing on an expressway in Uttar Pradesh by its Rafale, Su-30 and Jaguar fighter jets to demonstrate ‘operational readiness’. In response Pakistan test-fired its Abdali ballistic missile that can carry a nuclear warhead and has a range of 450km.&nbsp;
The danger is that with ultra-nationalist rhetoric and the beating the war drums by both sides, India’s government and Pakistan’s military may have to ‘do something’ to appease domestic public opinion. But any tactical strike, an artillery exchange, or territorial incursion could quickly escalate out of control.
Expecting an Indian retaliation for the Pahalgam killings, Pakistan is using<a href="https://nepalitimes.com/opinion/interfaith-collaboration-for-nuclear-disarmament"> nuclear deterrence </a>and warning of “catastrophic consequences”. The two neighbours came close to a nuclear exchange in 2019 after an attack on the Indian military in Kashmir, and prompt international intervention led by the United States cooled tensions.&nbsp;
This time, the <a href="https://nepalitimes.com/news/trump-shock-wave-hits-nepal">Trump administration</a> is too distracted and not as engaged. Pakistan has denied it was responsible for the terrorist attack and called on Washington to stop a possible Indian retaliation. India and Pakistan have stopped overflights by each other’s airlines, and some international carriers have even stopped flying over Pakistan fearing an air war.
Washington, Beijing, the UN and the EU have all urged restraint. Iran, which has good relations with both India and Pakistan has sent its foreign minister to urge both countries not to go into a tit-for-tat war. Iran has its own nuclear flashpoint to worry about with tensions in Israel, &nbsp;Yemen and Syria.
India and Pakistan both share similar problems of joblessness, <a href="https://nepalitimes.com/here-now/why-nepal-s-poverty-rate-is-stuck">poverty </a>and <a href="https://nepalitimes.com/here-now/climate-change-new-threat-to-nepal-s-rhinos">environmental threats</a>. Neither side needs the threat of a senseless war, and we in the neighbourhood do not need it either.&nbsp;

Hundreds of <a href="https://archive.nepalitimes.com/article/nation/Singati-rising-from-rubble-rebuilding,3703">Singati survivors</a> had lined up for food and relief supplies in the morning of 12 May when the second earthquake triggered a rock slide that buried a nearby camp. At least 50 people were killed. &nbsp; Three hours later, a US Marine Corps UH-1Y Venom helicopter landed in a nearby cornfield to pick up the wounded, and flew off. The aircraft lost contact with air traffic control in Kathmandu and its wreckage was located high on Kalinchok four days later. Six American servicemen, two Nepal Army soldiers, and five wounded civilians from Singati were killed. Today, Singati bears little physical scar of the multiple tragedies that struck the town ten years ago.

Climate magnifies earthquake risk in Nepal village

The streets of Patan are alive this month with lavender jacaranda trees under rain-washed skies as <a href="https://nepalitimes.com/banner/the-red-god-rises-again-in-patan">the chariot of Rato Matsyendranath</a> is pulled across town. This is the festival of the rain god, and inevitably the heavens opened up and pre-monsoon showers pelted the chariot as it started being pulled in Pulchok last week. Thousands of devotees, onlookers and the chariot procession organisers thronged the streets on the first day last week. The rhythmic cymbals and drums exuded a vibrant energy as the enormous four wheels turned and the chariot lurched.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025051007050_81df97744db16f732a419dc1f1579d235ce3df37642b078f50b83bd4bd026688.jpg" data-media-id="editor_1" data-image-id="2025051007050_81df97744db16f732a419dc1f1579d235ce3df37642b078f50b83bd4bd026688" data-rendition-name="original" width="1000" height="1503" loading="lazy" alt="Divine chariot"> </figure>  The<a href="https://archive.nepalitimes.com/article/Nepali-Times-Buzz/Red-rain-god,3141"> red rain god</a> has Hindu and Buddhist antecedents, alternatively called Bungadya and<a href="https://nepalitimes.com/here-now/kathmandu-s-gravity-defying-chariot-festival"> Karunamaya</a> — reflecting Kathmandu Valley’s syncretic mixture of the two religions.&nbsp; “Bungadya is a profoundly <a href="https://nepalitimes.com/opinion/12-full-opinion/marketing-the-intangible">intangible form of heritage</a>,” explains heritage expert Monalisa Maharjan. “It embodies traditional knowledge,<a href="https://nepalitimes.com/multimedia/reviving-nepal-s-craft"> artisanal skills passed down through generations</a>. Local communities and specific families have specified roles in being custodians of the heritage, ensuring their survival over the centuries.” There are many legends and stories about this annual tradition. Lichhavi king Narendra Dev is supposed to have brought Rato Matsyendranath from Assam to Kathmandu Valley to convince Guru Gorakhnath to lift a spell that created a two-year drought in Kathmandu.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250510050520_347a9a398f8a9abc4a7fb4e2774fde8264cccbdce8bdab23851ab3f0e73c3e8a.jpg" data-media-id="editor_6" data-image-id="20250510050520_347a9a398f8a9abc4a7fb4e2774fde8264cccbdce8bdab23851ab3f0e73c3e8a" data-rendition-name="original" width="1503" height="1000" loading="lazy" alt="Divine chariot"> </figure>  Matsyendranath was Gorakhnath’s mentor, and upon seeing him, the serpents were released, unleashing the rains.

Patan does not sleep for a month as the chariot is pulled through various neighbourhoods. It unfolds at a state level with the president (formerly the king) attending the climax of the Bhoto Jatra in Jawalakhel later this month.&nbsp; The intergenerational transmission of tradition is unique in the world, and the reason the festival is one of the most vibrant cultural expressions that thrives despite inroads of modernity. The other unique aspect is that it is a transnational festival, binding Patan with Guwahati in the Indian state of Assam.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/2025051005058_8bc685ada13045d863b28e3eed91c931da2b510714586af6fd7eb5d1e298a24a.jpg" data-media-id="editor_9" data-image-id="2025051005058_8bc685ada13045d863b28e3eed91c931da2b510714586af6fd7eb5d1e298a24a" data-rendition-name="original" width="1000" height="1503" loading="lazy" alt="Divine chariot"> </figure>  “Unlike Nepal, where the deity commands grandeur and devotion, many in Assam are unaware of Rato Matsyendranath,” says Khagen Sharma of Gauhati University, which convened <a href="https://nepalitimes.com/news/nepal-assam-connection-revived">a symposium in February in Guwahati on the rain god</a>. Attending was a delegation led by Lalitpur Mayor Chiribabu Maharjan, organisers of the festival, and builders of the chariot. After the symposium, a committee was formed to explore and revive the tradition in Assam as well. Although the team had planned to visit Nepal this month, logistical challenges delayed the trip. Still, there are plans to build a Guru Matsyendranath statue in Assam to reestablish regular worship practices in the Guwahati shrine.&nbsp; The vines used to build the chariot in Patan are sourced from the jungles of Assam. But Sharma notes that in recent years unclear regulations have blocked the official import of the vines, although they are still brought to Nepal informally. The <a href="https://archive.nepalitimes.com/article/Nepali-Times-Buzz/makers-of-machhindranath,2204">chariot making</a> has also had a taste of modernisation in recent times. In the past, even a single nail or piece of steel was avoided. But over time, the wooden structure, particularly the shaft between the wheels, has been replaced with bronze. When that too proved unstable, metal clamps were introduced, which have become a pragmatic compromise.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250510050524_b2a819a5791612f14c81d30fc393dbd3f99f0c64b90a9110e8b0855d944bfa93.jpg" data-media-id="editor_12" data-image-id="20250510050524_b2a819a5791612f14c81d30fc393dbd3f99f0c64b90a9110e8b0855d944bfa93" data-rendition-name="original" width="1500" height="998" loading="lazy" alt="Divine chariot"> </figure>  Another welcome change is the focus on safety. Builders climbing the chariot’s tower now wear harnesses and there are efforts in crowd control. The most visible change in recent years has been the involvement of Patan’s enthusiastic youth in the festival — the tradition is now passing to a new generation. Says Matsyendranath expert Vidhu Kayastha: “There is more energy, the young people in red t-shirts this year were very organised, these modern touches aren’t diluting our culture, they’re keeping it alive in new forms.” He adds, “We are <a href="https://nepalitimes.com/here-now/searching-for-a-homeland-away-from-home">reconnecting with our roots</a>, we have more resources, more awareness than ever before. We must not be swept away by western values that may not serve us, and in some ways, cause more harm than good. We must revive our own culture.”&nbsp;
