The Los Angeles Basin is situated along the coast of Southern California at the confluence of the Transverse Ranges and the Peninsular Ranges.The basin is under the influence of several strike-slip and blind thrust faults with geodetic studies providing evidence of the northern basin being shortened in the north–south or northeast–southwest directions at a rate of 4.5–5 millimetres (0.18 ...

The epicenter region of the earthquake was located in the San Fernando Valley, about 30 km (19 mi) northwest of downtown Los Angeles. The United States Geological Survey (USGS) placed the hypocenter 's geographical coordinates at 34°12′47″N 118°32′13″W / 34.213°N 118.537°W / 34.213; -118.537 and at a depth of 11.31 miles ...
On Friday, at 10:26 a.m., a magnitude 3.6 earthquake — down from an original estimate of 3.8 — occurred with an epicenter just north of the Ojai Valley, causing weak shaking to be felt from ...
Probabilistic seismic hazard map. The earliest known earthquake in the U.S. state of California was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also ...
The Los Angeles Department of Water and Power, as well as the County of Los Angeles, investigated and verified that local soil conditions contributed to the ground displacement and resulting destruction. The area of surface breaks on the ground at the site was 900 ft (270 m) (at its widest) and stretched 4,000 ft (1,200 m) down a 1% grade slope ...
