CHP reports earthquake closes Grapevine lanes
The California Highway Patrol reports that as of around 10:30 p.m. Tuesday, two southbound lanes of I-5 over the Grapevine are closed after large boulders fell on the roadway after the earthquake.
The CHP doesn't have a timeline for reopening the lanes while emergency crews clear the area, so motorists are advised to drive cautiously.

Earthquake shakes Central Valley, parts of SoCal
An earthquake at 9:09 p.m. Tuesday of a preliminary magnitude of 5.3 centered 21 miles from Bakersfield shook the southern San Joaquin Valley and was felt in parts of southern California.
There were no immediate reports of damage. The U.S. Geological Survey's site typically recalculates the data within the first few hours of the earthquake, so figures can move slightly up or down.
The quake was followed by dozens of aftershocks ranging from 3.7 to 4.7 magnitudes. The Bakersfield Californian reported that downtown Bakersfield shook so much that there was little pause between the initial earthquake and the aftershocks.
The earthquake was centered in Lamont on the north side of the Grapevine, according to the U.S. Geological Survey.
Many residents throughout California received an emergency warning on their cell phones a few seconds before the quake hit.
Tuesday's earthquake is the most recent shaker to hit 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 thestate department of conservation, which tracks “big” earthquakes in California.
That earthquake struck in the early 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.

What am I supposed to do during an earthquake?
It depends on where you are at.
Here’s what to do in the following situations, according toReady.gov:
- Turn 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, then 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.
