Description
Kuldeep Dutta leads a five-author team tracing how two days of extreme rain in the Eastern Himalaya set off a chain of disasters in a 2026 study. In September 2020, heavy rain in Arunachal Pradesh triggered landslides that later flooded Assam plains. Satellite images mapped slides, debris flows, and flood extent. Rainfall records reaching back to 1996 set the event in context.
Slides briefly dammed streams, then the dams burst, sending sediment-laden water over a wide floodplain. Earlier wet spells had soaked the slopes before the peak daily rain hit. Total rainfall tracked storm length far better than peak intensity did. The authors argue that judging rain by both traits matters for warning systems in mountain-to-plain hazard chains.
