Bizarre, nine-day #seismic signal caused by epic #landslide in #Greenland
The source of the signal was eventually traced back to a massive landslide in Greenland’s remote #DicksonFjord. A staggering volume of rock and ice, enough to fill 10,000 Olympic-sized swimming pools, plunged into the #fjord, triggering a 200-meter-high mega-tsunami and a phenomenon known as a #seiche: a wave in the icy fjord that continued to slosh back and forth, some 10,000 times over nine days.
