Multiple factors appear to have combined to cause the catastrophic flash floods in Uttarakhand in early August 2025.
Immediate Triggers
Early media reports attributed the disaster to a cloudburst—an extremely heavy, localized rainfall event. They noted intense rainfall, over 100 mm per hour, falling in the Harsil Valley, which overwhelmed Dharali village and swept away homes and hotels .
ومع ذلك ، official data from the India Meteorological Department (IMD) contradicts this, indicating only 27 mm of rain recorded that day—far below the threshold for a cloudburst .
Experts now suspect that the flash flood was more likely driven by glacier-related events—such as a glacier collapse, a glacial lake outburst flood (GLOF), or a massive landslide—which released debris and water suddenly into the Kheer Ganga river. This torrent then swept through Dharali at devastating speed .
Underlying Risk Factors
The Himalayan region is facing accelerated glacial melting and increased formation of unstable debris. Rising temperatures and shifting precipitation patterns create conditions ripe for glacial snout detachments and sudden collapses—often referred to as “natural time bombs” .
Rapid, often unregulated infrastructure projects—like roads, hotels, and tourism facilities—have emerged along fragile hillside terrains. Construction debris, deforestation, and hillside excavation in ecologically sensitive zones (such as the Bhagirathi Eco-Sensitive Zone) further undermine slope stability, increasing disaster risk .
Summary: What Caused the Uttarakhand Flash Flood?
In short, while a cloudburst was initially blamed, current analysis points toward a glacial-related collapse or lake/landslide event as the primary cause—compounded by climate change-driven instability and weakened by human interference in the fragile landscape.
