Gorda Plate
The Gorda Plate is a small oceanic tectonic plate beneath the Pacific Ocean off the coast of northern California. It became a separate plate when it fractured from the Juan de Fuca Plate. The easterly side is a convergent boundary subducting under the North American Plate in northern California. The southerly side is a transform boundary with the Pacific Plate along an extension of the San Andreas Fault. The westerly side is a divergent boundary with the Pacific Plate forming the Gorda Ridge. The northerly side is a transform boundary with the Juan de Fuca Plate. The subducting Gorda Plate is connected with the volcanoes in northern California, namely, Mount Shasta and Lassen Peak. Lassen Peak erupted in 1911. The Gorda Plate and the Juan de Fuca Plate, are the last remaining fragments of the Farallon Plate, along with the Cocos Plate and Nazca Plate.
