Experts Say Glacier Collapse Sparked Deadly Flooding
Reuters reports that the massive, "Day After Tomorrow"-like flash flood along Nepal's border with Tibet, which completely wiped out a border crossing, could have been triggered by a massive glacier collapse.
Planet Labs satellite imagery reviewed by scientists showed that the lower section of a glacier broke away at an elevation of roughly 5,200 meters before plunging about 1,200 meters onto the valley floor.
"What I can see in this morning's satellite imagery from Planet Labs, the lower part of a glacier broke off at about 5,200 meters and crashed onto the valley floor about 1,200 meters below," scientist Dan Shugar, an associate professor at the University of Calgary, told the outlet.
