Its strength resulted from the abrupt release of plate tectonic forces, a process known as subduction, centered on an area beneath Honshu where it slides over the top of oceanic crust.

In high - pressure and high - temperature X-ray measurements that were partly conducted at DESY, scientists created conditions similar to those in so - called subduction zones where an oceanic plate dives under the continental crust.

Older crust in turn is then forced back down into the Earth's mantle in places where a continental plate meets an oceanic plate.
