Los Angeles sits among a network of active faults, including the San Andreas Fault to the north and east and the Puente Hills Thrust, which runs beneath downtown and is capable of M7+ earthquakes. Major faults include the San Andreas Fault, Puente Hills Thrust, Newport–Inglewood Fault, Hollywood Fault, and the Sierra Madre Fault. Notable quakes include the 1994 Northridge earthquake (M6.7), the 1987 Whittier Narrows earthquake (M5.9), the 1971 San Fernando earthquake (M6.6), the 1933 Long Beach earthquake (M6.4) and the 1857 Fort Tejon earthquake (M7.9). The seismic risk is very high. Tectonically, Los Angeles lies where the Pacific Plate slides past the North American Plate, with compression in the Transverse Ranges squeezing the basin. This page provides real‑time USGS data and historical context for Los Angeles.

The region is defined by San Andreas Fault, Puente Hills Thrust, Newport–Inglewood Fault, Hollywood Fault, Sierra Madre Fault, and the risk level is classified as Very High. With a population of 10 million, understanding local seismic hazards is crucial.
Los Angeles lies on Pacific Plate sliding past North American Plate, with compression in the Transverse Ranges. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.

Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
