Flurry Of Earthquakes Shake Lennox, Largest Measuring 4.0M

NEAR INGLEWOOD (CBSLA) – A swarm of earthquakes rattled the south Los Angeles County community of Lennox early Monday morning, the largest carrying a 4.0-magnitude which was felt strongly across L.A. and Orange counties.

The large earthquake occurred at 4:44 a.m., with its epicenter at Century Boulevard and Doty Avenue, just south of SoFi Stadium and north of the 105 Freeway and east of the 405 Freeway, according to the U.S. Geological Survey.

It happened at a depth of 12.3 miles.

The L.A. County Fire Department told CBSLA that it had not received any reports of damage.

The earthquake was felt as far north as Lancaster and as far south as San Juan Capistrano, per USGS. More than 6,400 people reported feeling it through USGS's "Did You Feel It?" platform.

"There have been more than 20 very small aftershocks," USGS scientist Robert DeGroot told CBSLA.

"Basically as the energy is moving from the depth of the earthquake to the surface, that energy is beginning to dissipate," DeGroot added.

It was preceded by a 3.3-magnitude earthquake which hit at 4:15 a.m., also in Lennox, about a half-mile from the larger quake, with the epicenter at West 104th Street and Dixon Avenue, according to the USGS.

"I felt the small tremble first, and I said something's going on, but then I went back to sleep, and then about 30 minutes later, boom, the big tremble hit," Inglewood resident Wilbert Williams said.

Noted seismologist Dr. Lucy Jones tweeted that the 4.0-magnitude quake was "not probably on any mapped fault."

Still, falling back to sleep was not an option for many.

"Definitely scared me, woke me up outta my sleep," said one Inglewood man. "It was my alarm clock this morning."

On Sunday afternoon, a 3.4-magnitude earthquake rattled the Riverside County city of Beaumont.

On April 1, a 3.2-magnitude earthquake struck Huntington Park in southeast L.A. County.

A pair of massive earthquakes struck the Kern County region of Ridgecrest and Searles Valley in the Mohave Desert on consecutive days in July of 2019. On the morning of July 4, 2019, the region was hit by a magnitude 6.4 quake, the largest to hit Southern California in 20 years. However, that turned out to only be a foreshock to the main shock, the magnitude 7.1 earthquake which struck on the night of July 5, ten times larger than the 6.4 quake.
