[Regnum] Due to global warming and the melting of polar ice, there is a risk of megatsunamis, in which the height of waves can reach 150 meters. This is reported by New Atlas.

According to scientists from the University of Potsdam, such waves will move at high speed, destroying everything around them. They can be caused by the collapse of large pieces of ice and rocks into the ocean.

According to university staff, it was the melting glaciers that caused the tsunami that hit Dixie Island on the east coast of Greenland in 2023.

As reported by the Regnum news agency, scientists have discovered methane emissions up to 700 m long and 70 m wide in the depths of Antarctica. Methane accumulated in the depths of the sea about 20 thousand years ago as a result of the decomposition of organic matter.

According to geologists, there are 24 gigatons of carbon accumulated in methane hydrates in Antarctica. The gas probably breaks through from the depths of the Earth along faults. Instability of marine sediments can lead to giant landslides on the continental slope and cause a tsunami.
