Unlike most tectonic plates , the Gorda Plate experiences significant intraplate deformation inside its boundaries . Numerous faults have been mapped in both the sediments and basement of the Gorda Basin , which is in the interior of the plate south of 41.6 ° N. Stresses from the neighboring North American Plate and Pacific Plate cause frequent earthquakes in the interior of the plate , including the 1980 Eureka earthquake ( also known as the Gorda Basin event )
