Dozens of small earthquakes have struck across Southern California within the past 24 hours, including more than 80 quakes occurring in Los Angeles County, local officials say.
The region was hit by six earthquakes of magnitude 2.5 or greater during this time, according to the U.S. Geological Survey. The strongest of these quakes was a 3.4-magnitude recorded off the coast of Catalina Island early Saturday morning.
The quakes started Friday with a 2.5-magnitude earthquake, which struck 3.7 miles southwest of Ojai in Ventura County at 10:46 p.m. Hours later, a 2.7-magnitude earthquake shook the Los Angeles neighborhood of Westmont, east of LAX, at 12:34 a.m. Saturday.
At 4:03 a.m., a 2.6-magnitude earthquake struck roughly 17 miles southeast of Avalon. A 3.0 hit the same area at 4:11 a.m. The two quakes were followed by the larger 3.4-magnitude quake that struck near Catalina Island at 4:13 a.m.
At 4:32 a.m., another small quake (2.6 magnitude) occurred near Westmont at 4:32 a.m.

These are the largest earthquakes to hit the region in the past 24 hours. However, more than six dozen smaller earthquakes shook the area during this period.
A map of the earthquakes provided by the USGS shows the region covered in dots representing the recent earthquakes. The Westmont region has been especially active, the map shows.
The most recent earthquake to hit the Los Angeles area was a 1.8-magnitude quake that struck at 2:29 p.m.
The State of California and County of Los Angeles have a number of resources available for earthquake preparedness. Residents of the state are encouraged to always be prepared for a major earthquake, which could occur at any time.
According to a recent study, the San Andreas Fault and San Jacinto Fault Zone are at their highest stress levels in 1,000 years.
