Seismic forensics could inform a warning system for future floods

Sept. 30 (UPI) -- Seismic forensics could help scientists develop an early warning system for rockslides and floods in the future. On Feb. 7, 2021, a large rockslide trigged a deadly flood in India's Dhauli Ganga Valley. The rush of water killed more than 200 people and destroyed a pair of hydroelectric power plants. In a new study, published Thursday in the journal Science, researchers used data from a network of seismometers to piece together the minute-by-minute seismic signatures of the rockslide and subsequent flood. Although scientists have yet to determine what exactly triggered the catastrophe, they know that just after 10:20 in the morning, local time, 20 million cubic meters of ice and rock plunged down the slopes Ronti Peak, a mountain glacier, and into the Ronti Ga...
