Satellite Images Show Bedrock and Glacier Collapsed on Nepal-China Border, Then Rivers Flooded
Satellite images showed a bedrock failure beneath the glacier that sent ice and debris into the valley, killing hundreds and leaving hundreds missing.
- On Wednesday, a massive bedrock collapse beneath Langtang Lirung peak triggered catastrophic flash flooding along the Nepal-Tibet border, killing over 460 people and sweeping through villages.
- Geomorphologists Kristen Cook and Dan Shugar identified a combined glacier and bedrock failure as the cause, correcting initial USGS reports that suggested an earthquake triggered the disaster.
- The Nepal Tourism Board reported Thursday that over 600 foreigners, including 65 Americans, remain missing, while flooding destroyed buildings in Syapru Besi and wiped out the Rasuwagadhi crossing.
- Satellite images of Kolpurtar, Betrawati, and Syapru Besi show the Trishuli River widened significantly and turned brown from heavy sediment, with the powerful flow pushing upstream.
- University of Colorado Boulder geographer Alton Byers linked the disaster to climate change, stating permafrost is "weakening and becoming unstable," though Cook and Shugar cannot currently establish a direct link.

Satellite Images Of Nepal Before And After Floods
Comparative satellite imagery of the Nepal-China border captured before and after August 26 reveals massive devastation across the region following catastrophic flash floods on Wednesday.The high-resolution orbital photos display a stark transformation along the rugged frontier. Swollen rivers breached their banks, triggering sweeping landslides that engulfed infrastructure, washed away critical roadways, and severely damaged remote settlements …
"We fled to save our lives, "everything had disappeared, only the river remained, and "we had only 20 seconds to react, "are the testimonies of people who have escaped with life from the path of devastating life from the border between Nepal and China.

From the cockpit of a helicopter, with the cameras recording and pointing down, a group of crewmen contemplated something that no flight manual had foreseen. Under their feet, on the border between Nepal and Tibet, a glacier lake had just been suddenly emptied. The images, engraved at bird’s eye, show first the lake as it was before the flood by sudden overflow. A water mirror embedded between mountains, in apparent calm, reaching its highest le…
