Megathrust earthquake?
A megathrust earthquake is a very large earthquake that occurs in a subduction zone, a region where one of the earth's tectonic plates is thrust under another. The Cascadia subduction zone is located off the west coast of North America. From mid Vancouver Island to northern California the Juan de Fuca Plate is subducting beneath the North American Plate. The two plates are continually moving towards one another, yet become "stuck" where they are in contact. Eventually the build-up of strain exceeds the friction between the two plates and a huge megathrust earthquake occurs.!!

A megathrust earthquake is an inter-plate earthquake where one tectonic plate slips beneath another. Due to the size of the tectonic plates and the shallow dip of the plate boundary, these earthquakes are among the world's largest , with moment magnitudes that can exceed 9.0.
