On a day when the region was already dealing with a major tropical storm, a powerful earthquake centered in Ventura County shook most of Southern California today.
The quake, with a magnitude of 5.1, struck at 2:41 p.m. in Ojai, according to the US Geological Survey.
It was quickly followed by a series of aftershocks, the largest being a magnitude 3.6.
There were no immediate reports of injuries or damage attributed to the quake, but it was widely felt throughout the region, with shaking being felt in Los Angeles County’s South Bay and Riverside County.
Earthquake expert Lucy Jones wrote on X, formerly Twitter, that the shaking appeared to have been preceded by a series of preliminary tremors that began Saturday morning.
The quake struck on a day when the remnants of Hurricane Hilary, which weakened to a tropical storm before making landfall, was bringing heavy rain to southern California and first responders were already on high alert.
The National Weather Service said a tsunami threat was not expected from the quake.
