4.7 quake near LAX is felt across wide area


A 5.0 earthquake struck southeast of Los Angeles International Airport this evening, causing significant shaking across Southern California. [Update: Quake was downgraded to 4.7.]

The temblor hit about 8:30 p.m. a mile from the South Bay community of Lennox. 

There were no immediate reports of damage or injuries, but authorities said they were receiving numerous calls about the temblor.

A 3.0 aftershock occurred a few minutes later near Lennox.

Check out the USGS quake map.

Update at 8:58 p.m.: The temblor started about 8.4 miles below the surface, according to the U.S. Geological Survey. Residents in the Lennox area said china fell off shelves, but there were no reports of more serious damage. The Los Angeles Fire Department is on "emergency quake mode" as a precaution.

It's unclear what fault the quake struck on. The Newport-Inglewood fault, which has produced several powerful temblors, runs through that general area.

Updated at 9:10 p.m.: An initial assessment by the Los Angeles Fire Department found "no major structural damage, no serious injuries," according to spokesman Brian Humphrey's Twitter feed. 

Updated at 9:20 p.m.: At the Los Angeles County Sheriff's Lennox station, deputies said the shaking was brief but intense. "It was pretty strong but over in about 10 seconds," said Lt. Kent Wegener. "There are no [immediate] reports of damage. At this point, we are checking all the critical facilities and getting our ducks in a row." 

Los Angeles County Fire officials also said they had not received damage reports in residential or industrial areas, including the coastal refineries.

Update at 9:35 p.m.:KCAL interviewed moviegoers at a shopping mall in Redondo Beach who said the quake shook the screen and caused some ceiling tiles to fall. But firefighters said there was no serious damage or injuries. KCAL also reported numerous burglar alarms going off and some people cutting themselves on glass.

Updated at 9:50 p.m.: In Hawthorne, firefighters were called to Chadron Avenue, near Crenshaw Boulevard, where a light pole was damaged during the earthquake. One man also suffered a heart attack, but it was unclear whether that was connected. “Luckily, nothing major so far,” said Hawthorne Police Lt. Michael Ishii.

The earthquake was “a bit deep,” said U.S. Geological Survey seismologist Susan Hough – originating 8.4 miles below the surface. “That tends to make it less sharp – less of a jerky, abrupt motion,” Hough said. As a result, most of the region felt the quake largely as a rolling motion, though some closer to the center felt more of a jolt.

Lucy Jones, seismologist at the U.S. Geological Survey, said  the earthquake appears to be consistent with a rupture on the Newport-Inglewood fault. (She said the quake was too small to break the surface, so they can't definitively identify faults.) Jones said this fault isn't typically thought to be capable of producing a major quake like the San Andreas fault. But it was responsible for the 1933 Long Beach earthquake, which measured about 6.3 in magnitude. The Long Beach quake was about as big as seismologists expect from this fault, she said.

"There have been numerous magnitude 3s on it over the years, a cluster of them in the 1980s," she said. "In general, it's an active area."

The quake was initially logged as a magnitude 5 by automatic sensors, but as more data came in, seismologists downgraded it to a magnitude 4.7. It also had an aftershock with a magnitude 3.1 about six minutes later. So far, Jones said, 12,000 people have reported feeling the shaking, including some people in San Diego. She was not surprised at the number of people reporting because the quake shook a pretty densely populated area.

Nothing about the quake or its aftershocks looked unusual, she said. "It’s a real garden variety California earthquake so far."

 What’s notable about it is location with respect to people.

She said the most similar earthquake to this one was a temblor that shook the Inglewood area in 1920, and that one was classified as a "minor damaging shock."

It wasn't too bad in Santa Monica. At first I didn't know if it was a tremor or rowdy neighbors

We felt it here in Reche Canyon/Colton. Just mild shaking and a rolling feeling. We are doing fine.

Did not feel a thing up here in Santa Barbara.

We were watching Mel Brooks History of the World Part I -- the house shook during the French Revolution right when the angry mob knocked down the palace door. It was a very cool special effect.

We felt it down here in Chula Vista.

Felt it here in Koreatown, there was a significant long tremor felt on the 6th floor, while nothing fell down it did feel like a strong 'shake-down'.

Significant shake in Manhattan Beach but no structural damage or anything like that. Just a bit of a scare. Definitely felt an aftershock about five minutes later....

Felt it in South Park of San Diego. Wasn't bad. It felt like the dog ran thru the house....

I felt it pretty good out in Hemet.

Barely felt it at San Diego State Univ.

It brought the neighbors out in Corona del Mar, it was short but strong enough to get us all up and out

Felt it in Hollywood...Took me a minute to figure out what was going on and then jumped in the doorway but nothing happened! Lasted longer than normal though cause I usually don't have time to get in the doorway!!!

Here in Lakewood it was felt. Probably lasted 10 seconds but felt very forceful. I live in 2nd floor of apartment complex. I did not feel any aftershocks or swaying.

Some items fell off bookshelf. Immediately after it was over, I took down glass objects (vases, etc) in case another jolt came later.

Scary feeling.

We felt it in Woodland Hills. Well...at least on the 2nd floor! I did not feel it on the first floor but the rest felt it upstairs.

It was about 30 seconds long and really loud here in Lakewood. A couple of pictures were shaken ajar and a couple of minor things fell of shelves but no damage. It really set the dog off, though. Now she probably thinks she chased it away with her barking! :-D

I felt it here in san gabriel california it was pretty strong but not too long I immediately stood by the door just in case.

It is not recommended to occupy a doorway during an earthquake. A swinging door can lead to serious injury

Definitely felt it in PV. This was the first one my kids ever felt, so they were pretty scared, but no damage here. As soon as it hit, I knew we were close to the epicenter. It wasn't the usual rolling sensation, but sharp jerking. Not fun, but over quickly.

Manhattan Beach is near the quake and shook the house and broke a lamp

Santa Monica: felt it on 5th floor of old brick apartment building. First a sharp jolt, then a wave of shaking for 5-10 seconds. No damage.

Thanks LA Times for being first on the scene, despite typos.

3rd floor apt in Irvine. Had a few frames broken. Felt a really scary shake for a good 15 seconds. It was a pretty scary one... Maybe because of 3rd floor?

Did not feel it in Vegas. Probably will want to be here when the San Andreas finally pops, though maybe not in the new sky scrapers.

Felt it in San Diego. It lasted for about 5 seconds and caused a cracking noise in my walls.

I live in San Diego, near La Jolla, and I felt it. However, my friends who live in other areas like Clairemont, downtown San Diego, and University City didn't feel it. It's strange.

I'm in downtown L.A. (5th Street) and I definitely felt it here. The floor shook and my vertical blinds swung back-and-forth for probably the whole 10-15 seconds. It was long enough that I was starting to wonder when it would end. No damage, though.
