A landslide in Greenland, caused by climate change, created a huge tsunami, as a result of which the Earth vibrated for 9 days, according to new research by scientists from the University of California, DPA reported.
The giant waves generated by the tsunami crashed back and forth in a fjord in Greenland, sending vibrations across the globe, researchers say.
The study found that this movement of water was the cause of the mysterious global Earth vibrations that lasted 9 days and puzzled seismologists last September.
Invisible to the human eye, the landslide caused seawater to rise 200 meters into the air, with waves as high as 110 meters.
The researchers calculated that this wave, which rose along 10 km along the length of the fjord, decreased to 7 meters within a few minutes, and in the following days to several centimeters.
Scientists suggest that the landslide was caused by the thinning of the glacier at the foot of the mountain, which was unable to hold the rock mass above it. After all, according to the researchers, climate change was the cause, and the landslide and tsunami were the first of their kind observed in East Greenland.
The international team estimates that about 25 million cubic meters of rock and ice (enough to fill 10,000 Olympic-sized swimming pools) collapsed into the fjord. Scientists also confirmed the size of the resulting tsunami – one of the largest seen in recent history – using digital simulations as well as local data and photographs.
