Underwater earthquakes collapsing could mean more tsunamis

New research shows that mountains under the Pacific Ocean are the site of one of Earth's most violent natural processes. Images taken by underwater sonars show that the massive volcanic mountains are being dragged into an abyss. 

The abyss is where the Pacific plate collides with the Indo-Australian plate. And it is up to 10.9km deep at some parts.

The underwater trench is easily large enough to swallow up Mount Everest. Volcanoes near its edge have already started to collapse. And frequent earthquakes make the region vulnerable to tsunamis.
