Mendocino Triple Junction

The Mendocino Triple Junction is a geologic triple junction where the San Andreas Fault meets the Mendocino Fault and the Cascadia subduction zone, separating three tectonic plates: the Pacific Plate, the North American Plate and the Gorda Plate. It is located just offshore of Cape Mendocino in northern California.^[1]

It is one of the most seismically active regions of the San Andreas transform system. Since 1983 the region has generated about 80 greater than or equal to M3.0 quakes each year, and historically the region has experienced major quakes. This activity is generated in response to ongoing plate motions between the Gorda, North America, and Pacific plates.^[1]
