Moderate Earthquake Shakes Southern California

Moderate Earthquake Shakes Southern California

Moderate Earthquake Shakes Southern California, A moderate earthquake rattled Southern California on Saturday morning, shaking homes across the Inland Empire region and causing buildings to sway in downtown Los Angeles.
The magnitude 4.1 quake struck at 8:07 a.m. The U.S. Geological Survey said it was centered along the San Andreas Fault about two miles northwest of Devore, in San Bernardino County. Some buildings swayed in downtown Los Angeles, about 60 miles to the west.
A San Bernardino County Sheriff's dispatcher said the Rancho Cucamonga station shook for a few seconds, but there were no calls about damage or injuries.

A small 2.0 magnitude aftershock hit about a half-mile away about two minutes later, the USGS said.

Paul Harrington was reading in bed at his home in Hesperia, about 20 miles north of the epicenter, when he felt the quake hit.

"It started out as a little tremble, like a plane passing overhead. Then a few seconds later, there was a real jolt," Harrington said. "A few seconds after that there was another smaller jolt."

Harrington said he felt the shaking for about 30 seconds. His home was not damaged.

A clerk at an Albertson's market in Rancho Cucamonga said the store shook for several seconds but nothing fell from shelves.

The epicenter was approximately where the San Andreas Fault crosses the San Gabriel and San Bernardino mountain ranges.
Weak shaking was felt in a vast area. Below are the cities where weak shaking was reported to be felt (full city list).

M 4.1 light shallow earthquake shakes Southern California (@ 10 km depth) today with epicenter located 3 km NW from Devore. Light shaking will have felt by the people of Muscoy.

Southern California (SoCal) is a megapolitan area in the southern area of the U.S. state of California which includes Greater Los Angeles and Greater San Diego.
Earthquakes in California are common as the state is located on the San Andreas Fault, which cuts across California and forms the tectonic boundary between the Pacific and the North American Plate.
The largest recorded earthquake in California was the 1857 Fort Tejon earthquake of Magnitude 8.0
Two minor M 2.0 aftershocks were recorded after this quake.
A moderate earthquake rattled Southern California on Saturday morning, shaking homes across the Inland Empire region and causing buildings to sway in downtown Los Angeles.

The magnitude 4.1 quake struck at 8:07 a.m. The U.S. Geological Survey said it was centered along the San Andreas Fault about two miles northwest of Devore, in San Bernardino County. Some buildings swayed in downtown Los Angeles, about 60 miles to the west.

"It started out as a little tremble, like a plane passing overhead. Then a few seconds later, there was a real jolt," Harrington said. "A few seconds after that there was another smaller jolt."
Harrington said he felt the shaking for about 30 seconds. His home was not damaged.
A clerk at an Albertson's market in Rancho Cucamonga said the store shook for several seconds but nothing fell from shelves.
The earthquake had about 1 percent of the energy of the Northridge quake, said Thomas Heaton, director of the earthquake engineering and research laboratory at the California Institute of Technology.The magnitude-5.9 Whittier Narrows quake in 1987 was the last large one centered in the region hit Tuesday. That quake heavily damaged older buildings and houses in communities east of Los Angeles.
"People have forgotten, I think, what earthquakes feel like," said Hutton. "So I think we should probably look at it as an earthquake drill. ... It's a drill for the `Big One' that will be coming some day."
'Get under the tables'
Disneyland visitor Clint Hendrickson, 32, said he was in the Golden Horseshoe theater watching a show when the temblor hit.
"The ground moved and the chandelier started shaking," he said. "We are from Texas and we thought it was part of the show, until people started yelling, 'Get under the tables!'"Attractions at Disneyland and Disney's California Adventure theme parks and at the Knott's Berry Farm theme park were temporarily closed for inspections after the shaking.
The quake interrupted a meeting of the Los Angeles City Council, causing the 27-story City Hall to sway just as Councilman Dennis Zine was criticizing a plan to increase trash fees.
"And there goes the earthquake — earthquake, earthquake, earthquake!" said Zine, as members of the audience began to cry out. "The building is rolling!"
Scattered reports of minor damage
California's Office of Emergency Services received scattered reports of minor infrastructure damage, including broken water mains and gas lines.
"Nothing serious enough to be an immediate threat to lives, but there is some disruption to utility service," spokesman Kelly Huston said. The damage was in the greater Los Angeles area.
Minor structural damage was reported throughout Los Angeles, along with five minor injuries and people stuck in elevators, said City Councilwoman Wendy Greuel, serving as acting mayor. She said there was flooding in one department store.
The Great Southern California ShakeOut is based on a potential magnitude 7.8 earthquake on the southern San Andreas Fault— approximately 5,000 times larger than the magnitude 5.4 earthquake that shook southern California on July 29. It’s not a matter of if an earthquake of this size will happen—but when. And it is possible that it will happen in our lifetime.
