The Mendocino Fracture Zone between the Gorda Plate and Pacific Plate. The Mendocino Fracture Zone is a fracture zone and transform boundary over 4000 km (2500 miles) long, starting off the coast of Cape Mendocino in far northern California.It runs westward from a triple junction with the San Andreas Fault and the Cascadia subduction zone to the southern end of the Gorda Ridge.Most earthquakes cluster along or between the mapped Iapetan faults (also called St. Lawrence paleo-rift faults). CSZ earthquakes occur in the Canadian Shield, between the surface and 30 km depth, beneath Logan's line and the Appalachians.
