How do the Juan de Fuca Gorda and Pacific tectonic plates influence the geology of the Pacific Coast states?

The Juan de Fuca, Gorda, and Pacific tectonic plates interact along the Cascadia subduction zone, significantly influencing the geology of the Pacific Coast states, particularly Washington, Oregon, and Northern California. This subduction process leads to volcanic activity, forming the Cascade Range, and creates numerous earthquakes due to the tectonic stress along the plate boundaries. The ongoing interactions also contribute to coastal erosion and the formation of unique geological features, such as deep oceanic trenches and accretionary wedges. Overall, the dynamic movements of these plates shape the diverse landscapes and seismic activity of the region.
