Los Angeles, California – A brief jolt woke some residents across northern Los Angeles County early Wednesday morning as a small earthquake struck near Castaic, with shaking most noticeable along the Interstate 5 corridor within seconds of the event.
According to the U.S. Geological Survey, the magnitude 2.8 earthquake hit at 2:04 a.m. local time about 5 kilometers north-northeast of Castaic at a depth of 11.7 kilometers. Sensors across Southern California quickly detected the tremor, and early public reports followed within minutes.
Areas outside Santa Clarita, including communities along I-5 toward Gorman and near Pyramid Lake, likely felt the strongest movement. Drivers on elevated ramps and overpasses may have noticed a quick shake, though no damage or closures were reported. Light motion may have extended into foothill regions of the Antelope Valley and nearby canyon communities.
Quakes of this size rarely cause damage but can still startle sleeping residents. Officials recommend securing loose household items and reviewing emergency plans as a precaution.
Seismic activity remains low-level, though minor aftershocks cannot be ruled out through Wednesday morning.
