Glacial Lake Outburst Floods pose growing threat in Uttarakhand
IN · Published Oct 21, 2026
• Glacial Lake Outburst Floods (GLOFs) are becoming an increasing concern in Uttarakhand due to the formation and expansion of moraine-dammed glacial lakes.
• Rising global temperatures are accelerating this process, creating conditions for sudden, high-velocity flash floods.

Impact & Risks

GLOFs pose a significant risk to communities living in the steep mountain valleys of Uttarakhand. These events can lead to catastrophic flooding, causing loss of life, destruction of property, and environmental degradation. The limited response time during GLOFs makes evacuation and disaster management extremely challenging. The risk is further compounded by the potential for triggering events such as earthquakes or cloudbursts, which can destabilise glacial lakes and initiate floods.
