The fault is on the boundary of four major geologic provinces: the Basin and Range, Idaho-Wyoming Thrust belt, Rocky Mountain Foreland, and the Yellowstone volcanic plateau. The Basin and Range province is a region of east–west crustal extension. This province adds tension perpendicular to the fault line causing the fault blocks to move apart.
The probability of a serious earthquake on various faults has been estimated in the 2008 Uniform California Earthquake Rupture Forecast. According to the United States Geological Survey, Southern California experiences nearly 10,000 earthquakes every year. [3] Details on specific faults can be found in the USGS Quaternary Fault and Fold Database.
A multi-year study published in 2018 suggests a connection between the Elsinore fault and other fault lines farther south, in Mexico: "...observations of the Yuha Desert and Salton Trough suggest that the 2010 M7.2 El Mayor ‐ Cucapah earthquake rupture, the Laguna Salada fault in Baja California, Mexico, and the Elsinore fault in California ...
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.

[8] In 1881, Henry Winter ("Hard Winter") Davis, established the Spectacle Ranch near the present site of Sussex, Wyoming.

Several faults run through Stanislaus County, including the Great Valley thrust fault system. The series of lines runs along the west side of the San Joaquin Valley, said Belle Philibosian, a ...
The San Jacinto Fault Zone and the San Andreas Fault (SAF) accommodate up to 80% of the slip rate between the North American and Pacific plates.The extreme southern portion of the SAF has experienced two moderate events in historical times, while the SJFZ is one of California's most active fault zones and has repeatedly produced both moderate and large events.
