A magnitude 4.0 earthquake was reported Monday morning at 4:44 a.m. near Inglewood, less than half an hour after a smaller foreshock hit the same area.The quake was felt across Southern California, according to the U.S. Geological Survey. The magnitude 3.3 temblor that preceded it hit at 4:15 a.m. There were no immediate reports of any damage.The larger quake was centered near the intersection of Prairie and Century boulevards. It occurred less than a mile from Lennox, less than a mile from Hawthorne, one mile from Los Angeles and one mile from Del Aire.It was followed by several smaller quakes in the Inglewood and Lennox area.
Earthquake expert Lucy Jones said on Twitter that the main magnitude 4.0 quake was strong enough to be “felt by most people awake in LA” but noted that it had occurred “very deep” in the earth, about 12 miles down. She added it was likely not on any mapped faults. The foreshock and flurry of aftershocks occurred at about the same depth, Jones said.
The M4.0 that just happened was under Lennox, CA, near Inglewood. Very deep at 20 km, so everyone is at least 20 km away. Would have been felt by most people awake in LA. Movement was thrust, probably not on any mapped fault https://t.co/UIPbVH0kw5— Dr. Lucy Jones (@DrLucyJones) April 5, 2021
A KCBS-TV news broadcast was on air when the magnitude 4.0 temblor struck. “That was definitely an earthquake right there,” anchor DeMarco Morgan said after the light shaking. “You were not dreaming.”
In the last 10 days, there have been three earthquakes of magnitude 3.0 or greater centered nearby.An average of five earthquakes with magnitudes between 3.0 and 4.0 occur per year in the Greater Los Angeles area, according to a recent three-year data sample.Did you feel this earthquake?
