Subduction zone earthquake. The area where the earthquake occurred is a subduction zone where the Pacific Plate is subducting beneath the North American Plate. The crust of southern Alaska was compressed and warped due to plate movement prior to the great earthquake after the plates locked together.Crustal plate movement.he area where the earthquake occurred is a subduction zone where the Pacific Plate is subducting beneath the North American Plate.

Iceland is the largest island on the ridge because of the additional volcanism caused by the hot spot beneath the country, which moves slowly towards the northwest. The tectonic plates move towards east and west, and both the North American and Eurasian systems move to the northwest across the hot spot.he lithosphere consists of continental crust and oceanic crust that surfaces in the ocean basins. Simply termed, a tectonic plate, often also referred to as lithospheric plate, is a massive slab of solid rock that floats separately from the other tectonic plates, interacting with them along the boundaries.
