The Calaveras Fault is a major branch of the San Andreas Fault System that is located in northern California in the San Francisco Bay Area. Activity on the different segments of the fault includes moderate and large earthquakes as well as aseismic creep. The last large event was the magnitude 6.2 1984 Morgan Hill event.
The partial complete subduction and division of the Farallon Plate by the Pacific Plate, created the Juan de Fuca Plate to the north and the Cocos Plate to the south. The final stages of the evolution of California's continental margin was the growth of the San Andreas transform fault system, which formed as the Pacific Plate came into contact ...
The Mendocino triple junction is located at the eastern end of the Mendocino Fracture Zone where it approaches Cape Mendocino. The Mendocino triple junction (MTJ) is the point where the Gorda plate, the North American plate, and the Pacific plate meet, in the Pacific Ocean near Cape Mendocino in northern California.
The Imperial Fault Zone is a system of geological faults located in Imperial County in the Southern California region, and adjacent Baja California state in Mexico. It cuts across the border between the United States and Mexico .
The Newport–Inglewood-Rose Canyon Fault Zone. The Newport–Inglewood Fault is a right-lateral strike-slip fault [1] in Southern California.The fault extends for 47 mi (76 km) [1] (110 miles if the Rose Canyon segment is included) from Culver City southeast through Inglewood and other coastal communities to Newport Beach at which point the fault extends east-southeast into the Pacific Ocean.
The fault was first identified in Northern California by UC Berkeley geology professor Andrew Lawson in 1895 and named by him after the surrounding San Andreas valley. Eleven years later, Lawson discovered that the San Andreas Fault stretched southward into southern California after reviewing the effects of the 1906 San Francisco earthquake.
The Mendocino Fracture Zone between the Gorda plate and Pacific plate (only the active section is traced) The Mendocino fracture zone is a fracture zone and transform boundary over 4000 km (2500 miles) long, [ 1 ] starting off the coast of Cape Mendocino in far northern California .
The Gorda plate, located beneath the Pacific Ocean off the coast of northern California, is one of the northern remnants of the Farallon plate. It is sometimes referred to (by, for example, publications from the USGS Earthquake Hazards Program) [ 1 ] as simply the southernmost portion of the neighboring Juan de Fuca plate , another Farallon ...
