ISRO: Uttarkashi Flash Flood Caused by Ice Collapse, Not Cloudburst

• ISRO study reveals 2025 Uttarkashi flash flood was caused by an ice patch collapse, not a cloudburst.
• The devastating flood in Dharali, Central Himalayas, resulted from the sudden collapse of an exposed ice patch in the Srikanta Glacier's nivation zone.
• Satellite imagery confirmed 6.9 million kg of ice cascaded down, transforming into a high-speed ice and meltwater mixture.
• The report rules out Glacial Lake Outburst Flood (GLOF) and cloudbursts, identifying it as a "mass release event."
• Scientists warn of "emerging cryo-hydrological hazards" due to climate change making static ice patches unstable and prone to sudden collapse.
