A map displaying each of the seven major faults in the San Francisco Bay Area, and the probability of an M6.7 earthquake or higher occurring on each fault between 2003 and 2032 The slip on the San Andreas Fault which caused the 1906 San Francisco earthquake was visible in Wrights Tunnel along the South Pacific Coast Railroad after the earthquake
Simplified fault map of southern California The faults of Southern California viewed to the southeast, as modeled by the Southern California Earthquake Center. Highlighted in purple are the San Andreas Fault (left) and Santa Monica Bay complex (right). The foreground is in the Santa Barbara Channel, the east-trending zone marks the Transverse ...
The western segment extends to the San Gabriel Mountains and San Gabriel fault. The central segment includes mountains that range eastward to the San Andreas fault. The eastern segment extends from the Cajon Pass at the San Andreas fault eastward to the Colorado Desert. [1] The central and eastern segments (near the San Andreas fault) have the ...
The time duration of subduction began from around 165 Ma when the Farallon Plate replaced the Mezcalera promontory, until the San Andreas Fault straightening around 35 Ma. [ 1 ] [ 2 ] [ 3 ] As data accumulated over time, a common view developed that one large oceanic plate, the Farallon Plate, acted as a conveyor belt, conveying accreted ...
California Coast, Los Angeles to San Diego Bay. The Elsinore Fault Zone is labeled in the center running along the Santa Ana Mountains. NASA photo, 2008. The Elsinore Fault Zone is a large right-lateral strike-slip geological fault structure in Southern California.
The primary tectonic feature in California is the strike-slip San Andreas (SAF) system of faults that form part of the diffuse Pacific–North American plate boundary. This transform fault trends south-southeast through much of northern and central California, but turns more southeasterly at the southern end of the California Coast Ranges at a prominent restraining bend.
Geologic maps of the Maacama Fault The Maacama Fault is a right lateral-moving (dextral) geologic fault located in the Coast Ranges of northwestern California . It is considered to be the northernmost segment of the Hayward Fault subsystem of the San Andreas Fault zone.
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.
