What you need to know about earthquakes
Every year, there are about 500,000 earthquakes – 100,000 of which can be felt on the Earth’s surface. But how do earthquakes work? We explain.
Just the FAQs
LOS ANGELES — A magnitude 5.3 earthquake rocked the San Joaquin Valley late Tuesday, the U.S. Geological Service said, jangling nerves as Southern Californians prepared for bedtime.
The quake was centered in Lamont, California, about 21 miles from Bakersfield, California. It struck at about 9:09 p.m. PST. No injuries or damage were immediately reported.
The quake was followed by dozens of aftershocks ranging from 3.7 to 4.7 magnitudes. The U.S. Geological Survey’s site typically recalculates the data within the first few hours of the earthquake.
Tuesday’s earthquake was the most recent to strike California and was felt as far away as Los Angeles, about 104 miles southeast. Many residents in the region received an emergency warning on their cell phones a few seconds before the quake hit.
Renowned seismologist Dr. Lucy Jones, who changed the way people prepare for earthquakes, felt the quake and took to social media, adding that the temblor’s epicenter was near the White Wolf fault that produced a magnitude 7.5 quake in 1952 but that “it did not appear to be on that fault.”
“Like any quake in SoCal, there is a 5% chance that it will be followed by something bigger,” Jones said on X. “That means a 95% chance that this is the largest. We have never found any characteristic that makes a quake more likely to be a foreshock.”
A 3.3-magnitude earthquake centered on the west side of the Salton Sea was felt in parts of Southern California. On July 29, a magnitude 4.9 earthquake centered 14 miles northeast of Barstow, California, rattled the high desert and parts of Southern California.
When was the last big earthquake in California?
The most recent significant earthquake in the state — either a magnitude of 6.5 or greater or that caused loss of life or more than $200,000 damage — was the 6.4-magnitude earthquake that occurred in the Pacific Ocean near Ferndale in 2022, according to the state department of conservation, which tracks “big” earthquakes in California.
That earthquake struck in the morning hours multiple miles west of Ferndale on Dec. 20, 2022, USA TODAY reported. It indirectly caused two deaths and damaged homes and roads in Humboldt County.

It depends on where you are located during the event.
Here’s what to do in the following situations, according to Ready.gov:
Turn your face down and cover your head and neck with a pillow if you’re in bed.If you are outside, stay outdoors and away from buildings.If you are inside, stay. Avoid doorways and do not run outside.
To protect yourself during an earthquake, drop down to your hands and knees and hold onto something sturdy. Cover your head and neck with your arms and crawl underneath a sturdy table or desk to shelter.
If that’s not available to you, crawl next to an interior wall to get away from windows. If you are under a table or desk, hold onto it with one hand so that if it moves, you can move with it.

What if I’m driving during an earthquake?
Slow down and pull over as soon as it’s safe, according to the California Highway Patrol. Remain in the vehicle with your seat belt fastened, engine off, and parking brake set. Once the shaking stops, check your vehicle for damage and its occupants for injuries. Only begin driving when it is safe to do so. Once you can start moving again, do so slowly and cautiously, avoiding any areas of the road that appear to be damaged or obstructed, and continue to avoid bridges and ramps.
