ISRO Identifies Ice Patch Collapse as Cause of 2025 Uttarkashi Dharali Flood

ISRO scientists have identified the cause of the August 5, 2025, flash flood in Uttarkashi's Dharali village as the sudden collapse of a large ice patch on the Srikanta Glacier, rather than a cloudburst or glacial lake outburst flood. The ice mass, located in a high-altitude nivation zone, fell about 1,700 meters, triggering a rapid flow of water, mud, and debris that devastated the village. Rainfall before the event was light to moderate, ruling out heavy precipitation as the trigger.
