Unraveling Uttarkashi's Flash Flood: Natural Causes and Human Impact

A flash flood in Uttarkashi's Dharali was initially suspected to be caused by a cloudburst. However, experts refute this, citing insufficient rainfall data. Possible causes include ice or rockfall. Human activities and geographical vulnerabilities have exacerbated disaster risks. Observations from satellite images and scientific studies may soon provide clarity.

The recent flash flood in Uttarkashi's Dharali has sparked a debate over its cause, with the India Meteorological Department (IMD) stating insufficient rainfall data to categorize it as a cloudburst. The district received only 27 mm of rain, far less than the required 100 mm per hour for a cloudburst classification.

Experts suggest that alternative factors, such as falling ice, rock, or landslides, could have led to the flood. The region's geological makeup, consisting of unstable, young formations and tectonic faults, increases vulnerability to such disasters. Recent studies show a rise in extreme weather events, exacerbated by human activities like deforestation and unregulated development.

Efforts are underway to gain a clearer understanding of the disaster. Satellite images from the Indian Space Research Organisation and further scientific analysis are expected to shed light on the precise causes. Meanwhile, research highlights the critical impact of both natural and anthropogenic factors in increasing disaster risks in the Himalayas.
