What type of land form is created at the plate boundary in the us pacific north west

The cascading subduction zone is the area where volcanoes, earthquakes, tsunamis occur. Majorly, land form of earthquake prevails in this region.

Explanation:

The subduction zone in the Pacific North West region. The occurence of the earthquakes is due to the deformities under the ocean plates. The rate of movement of these tectonic plates created a hazard for the earthquakes where the Pacific plate is moving 3-4 inches per year. The plate motions are straining the Lithosphere leading to volcanoes.

Water flows along the east coast and across the western tropical pacific towards south america, while they both are directed towards that way,  el niño does not directly affect the southern flow of water along the coast.
