A deadly cascade catastrophic landslide in Uttarakhand state India on February 2021 damaged two hydropower plants, and more than 200 people were killed or are missing. Shugar et al. describe the of events that led to this disaster. massive rock ice avalanche roared down a Himalayan valley, turning into debris flow upstream from first plants. The sequence highlights increasing risk Himalayas caused by increased warming development. Science , abh4455, issue p. 300
