Megathrust
The term megathrust refers to an extremely large thrust fault, typically formed at the plate interface along a subduction zone, such as the Sunda megathrust. However, the term is also occasionally applied to large thrust faults in continental collision zones, such as the Himalayan megathrust. A megathrust … Meer weergeven Megathrust earthquakes occur at convergent plate boundaries, where one tectonic plate is forced underneath another.
