9. Mass Movement Geography in the News Mudflow in India’s Assam region, May 2022


At least 11 people have died in floods and mudflows triggered by heavy rain in India’s northeast region of Assam. Nearly 200,000 people in the region were cut off from the rest of the state, as roads and bridges were either blocked by mudflows or washed away.


The state’s disaster management agency said nearly 700 villages were underwater. The army sent helicopters to help with rescue efforts.


People had limited drinking water and sparse food supplies. Communications were also cut off and roads and railways were closed. The mudflow had washed away houses and fields of crops.


Mudflows and floods are common in India’s northern region. Scientists say they are becoming more frequent as global warming plays a role in the melting of glaciers there.
