Lake Cahuilla (/ k ə ˈ w iː. ə / kə-WEE-ə; [1] [2] [3] also known as Lake LeConte and Blake Sea) was a prehistoric lake in California and northern Mexico.Located in the Coachella and Imperial valleys, it covered surface areas of 5,700 km 2 (2,200 sq mi) to a height of 12 m (39 ft) above sea level during the Holocene.
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 ...
Lake Cahuilla is believed to have been full six times in the last millennium: roughly the periods of 930 to 966, 1007 to 1070, 1192 to 1241, 1486 to 1503, 1618 to 1636, and 1731 to 1733.
San Diego Trough Fault Zone. The San Diego Trough Fault Zone is a group of connected right-lateral strike-slip faults that run parallel to the coast of Southern California, United States, for 150–166 km (93–103 mi). The fault zone takes up 25% of the slip within the Inner Continental Borderlands. Portions of the fault get within 30 km (19 ...
San Diego State University and ... The authors of the paper discovered that large earthquakes along the fault usually occurred when Lake Cahuilla was filling up or was full of water from the ...
The Salton Trough is a result of crustal stretching and sinking caused by the combined actions of the San Andreas Fault and the East Pacific Rise, particularly the Gulf of California Rift Zone (GCRZ), the northernmost portion of the East Pacific Rise. The GCRZ and the San Andreas Fault both terminate near the south end of the Salton Sea, in an ...
The Puente Hills thrust fault is the same overall fault network that produced the Whittier Narrows – which measured a 5.9 magnitude, killed eight people and caused some $358 million in damage in ...
The Elsinore fault zone, not including Whittier, Chino, and Laguna Salada faults, is 180 kilometers (110 mi) long with a slip-rate of 4.0 millimeters/year (0.15 in/yr). It is estimated that this zone is capable of producing a quake of 6.5–7.5 M W. The projected interval between major rupture events is 250 years.
