Earthquake fault zones were conceived in the Alquist-Priolo Earthquake Fault Zoning Act (Alquist-Priolo Act). The intent of the Alquist-Priolo Act is to reduce losses from surface fault rupture. California created this law following the destructive 1971 San Fernando earthquake (magnitude 6.6), which was associated with extensive surface fault ...Here we examine the fastest moving faults in southern California, the San Andreas Fault (SAF) and the San Jacinto Fault (SJF). Three historic earthquakes ruptured at least 560 km out of a total considered length of 710 km of these faults in less than 60 years in 1800, 1812, and 1857; we ask if this is typical for the system.The northern San Andreas leveled San Francisco in 1906, but it’s been a lot longer since the southern part of the fault ruptured. On average, Southern California has seen big quakes every 110 to 140 years, based on records of past earthquakes and studies of earthquake faults. The last big quake near Los Angeles, a magnitude 7.9, struck Fort ...Similar to the 1994 Fault Activity Map, the 2010 map is accompanied by an extensive listing of the sources of fault maps and age determinations. In the 2010 Fault Activity Map, the faults are depicted in as much detail as possible at the scale of the map. Click here to view a larger image of the Fault Activity Map of California.

Researchers created a model that uses the movement at fault lines to understand river flow and vice versa. In California's Carrizo Plain, many stream channels are offset by movement along the San Andreas Fault. A new interpretive framework helps explain how stream channels and fault movement interact to shape the topography of the landscape.
Feb 8, 2024 ... During the lecture I noticed one or two of the fault lines that runs perpendicular to where the fault line bends near Southern California.
