45°N124°W / 45°N 124°W The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is capable of producing 9.0+ magnitude earthquakes and tsunamis ...
The Walker Lane is a geologic trough roughly aligned with the California / Nevada border southward to where Death Valley intersects the Garlock Fault, a major left lateral, or sinistral, strike-slip fault. The north-northwest end of the Walker Lane is between Pyramid Lake in Nevada and California's Lassen Peak [ 1 ][ 2 ] where the Honey Lake ...
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 Range. Faults in the upper left are part of the Eastern California Shear Zone, connecting northward with the Walker Lane region. Faults extend deeper than shown.
Map showing the San Jacinto Fault Zone outlined in red. The San Jacinto Fault Zone (SJFZ) is a major strike-slip fault zone that runs through San Bernardino, Riverside, San Diego, and Imperial Counties in Southern California. The SJFZ is a component of the larger San Andreas transform system and is considered to be the most seismically active ...
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. 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. It continues on west of its ...
Michael McGough. May 12, 2023 at 1:11 PM. A pair of moderate earthquakes that shook Northern California on Thursday and Friday happened near a region known as the Almanor Fault Zone, marking the ...
San Andreas Fault. The San Andreas Fault is a continental right-lateral strike-slip transform fault that extends roughly 1,200 kilometers (750 mi) through the U.S. state of California. [1] It forms part of the tectonic boundary between the Pacific Plate and the North American Plate. Traditionally, for scientific purposes, the fault has been ...
The Perris Block is the central block of three major fault-bounded blocks of the northern part of the Peninsular Ranges. The Perris Block lies between the Santa Ana Block to the west and the San Jacinto Block to the east. [1] The Perris Block, was named by Walter A. English in 1925 for the city of Perris, located near the center of the block.
