4.1 aftershock of magnitude 4.7 earthquake rattles the southland from Los Angeles to the U.S./Mexico border

Published on May 17, 2009 by Editor

LOS ANGELES – An earlier reported 5.0 earthquake is now being reported as a magnitude 4.7 earthquake, which struck tonight in South Los Angeles, and minutes later a magnitude 3.1 aftershock occurred, but no major damage or injuries were reported.

The “moderate” 4.7 quake struck shortly before 8:40 p.m., a mile east of Lennox, a mile south southeast of Inglewood and 10 miles south southwest of the Los Angeles Civic Center, according to Caltech.

The rumbling lasted 10 to 15 seconds and was felt throughout the Greater Los Angeles area and as far south as San Diego, according to various witnesses.

It was the strongest quake to strike the Southland since the magnitude 5.5 earthquake that hit in Chino Hills last July 29.

The 3.1 aftershock occurred just after 8:45 p.m. a mile north northwest of Hawthorne and 3 miles southwest of Inglewood, according to Caltech.

A 2.5 “microquake” also struck in the area at 8:44 p.m., according to Caltech.

No fires, structural damage or injuries due to the earthquake were reported in El Segundo, Inglewood, the city of Los Angeles or Los Angeles County, fire and police department officials from various agencies said.

In El Segundo, burglar alarms were triggered and the Chevron refinery had a “burnoff,” when excess refinery gases were burned, said Sgt. Mike Gill of the El Segundo Police Department. Burnoffs are standard procedure after an earthquake, Gill said.

The city fire department went on “earthquake emergency mode,” although there was no damage reported, according to police and fire officials.

Fire engines at stations in the quake area were initially taken out of their garages as a precaution but were later returned.

Officials at Los Angeles International Airport, which is near the epicenter, released a statement saying, “Operations are normal and there are no flight delays following preliminary inspections of terminals, the airfield, Sepulveda Tunnel and other areas of the LAX Central Terminal Area.”

A similar statement was issued by officials at John Wayne Airport in Santa Ana in Orange County.

    I was getting a tattoo at the time the quake came. I have a small line on the top of it now where the tattoo machine slipped. There won’t be any forgetting this quake. :)

    We all felt it pretty good here in Fallbrook although it was hard to tell the difference from the marine helicopters that fly over and rattle the windows the same.. this had a rolling feel to it.

    I was watching the Survivor finale on my couch when I felt a little shake, approx. 8:40pm. I live near Mt. Helix in La Mesa. My sister, sitting next to me, didn’t feel a thing.

    My family and I felt it in Fallbrook. It lasted about 5-7 seconds for us. Then I felt the aftershock about a minute later. It was so slight that only I felt it. It was rather odd–kind of like an up/down jump instead of being shaken about.

    Interesting that the news is saying this was on the Rose Canyon Fault. That runs from Inglewood to San Diego according to this map.

    I live on a slope in Fallbrook, the rolling was more intense than normal, but as always sort of fun. It lasted about 15 seconds for us. The most disturbing part was the noise caused by the movement in the structure of our home.

    I was in a hotel just a few miles from LAX. It started with the hotel feeling like it jumped in the air then it was a wild sort of rolling that lasted about 10 seconds. The first up/down jolt was alarming since we had no idea if it was going to get worse. We were very close to the epicenter.
