'It was a dramatic enough failure that it actually created seismic waves that are really distinctive of landslides.'
The first slide was east of Seward, detected on Sept. 14 as it fell onto Ellsworth Glacier. Geologist Bretwood “Hig” Higman said debris from that slide is estimated to be about 10 million tons in volume.
“There’s a steep mountainside there, that kind of the whole side of the ridge came down, hit the glacier and spread out across the glacier. It went all the way across to the other side of the glacier. It was a dramatic enough failure that it actually created seismic waves that are really distinctive of landslides,” Higman said.
“It’s almost 20 years ago now I wrote some code to look for signals of earthquakes that don’t start with a sharp jolt,” professor Goran Ekstrom said.Most earthquakes start with a sharp jolt which is measurable as a p-wave. The second landslide fell Saturday onto Lamplugh Glacier in southeast Alaska. Scientists initially thought it could have been at the same spot as a 2016 landslide, which was even bigger.
