Video shows where massive landslide occurred in Greenland that unleashed a “mega-tsunami”
A massive landslide triggered by climate change unleashed a 650-foot “mega-tsunami” that caused Earth to vibrate for nine days.
The trigger, not observed by human eye, was the collapse of a 1.2km-high mountain peak into the remote Dickson Fjord beneath, causing a backsplash of water 200 metres in the air, with a wave up to 110 metres high.A massive landslide triggered by climate change unleashed a 650-foot “mega-tsunami” that caused Earth to vibrate for nine days.Researchers estimated that 25 million cubic metres of rock and ice crashed into the fjord – enough to fill 10,000 Olympic-sized swimming pools.
Scientists say the consequences of a tsunami wave of that magnitude could have been “devastating” if a passenger liner had been in the area. The model predicted that the mass of water would have moved back and forth every 90 seconds, matching the recordings of vibrations travelling through the Earth’s crust all around the globe.
At the same time, news of a large tsunami in a remote northeast Greenland fjord reached authorities and scientists working in the area.They used images captured by the Danish military who sailed into the fjord just days after the event to inspect the collapsed mountain-face and glacier front along with the dramatic scars left by the tsunami.
