A massive landslide in a Greenland fjord created a huge tsunami that lasted for nine days, sending seismic waves across the globe.
The landslide, caused by melting glaciers, sent a 200-meter wave crashing into the fjord, where it was trapped and oscillated for days.
Scientists were able to use seismic data, satellite images, and photographs to pinpoint the source of the tsunami to a remote fjord.
This event is a stark reminder of how climate change is impacting the Arctic, with melting glaciers destabilizing mountains and creating potential hazards.
