Strong quake shakes Southern California
By ROBERT JABLON
Associated Press Writer
A strong earthquake shook Southern California on Tuesday, causing buildings to sway and triggering some precautionary evacuations. No immediate damage was reported.
The jolt was felt from Los Angeles to San Diego, and slightly in Las Vegas.
Preliminary information from the U.S. Geological Survey estimated the quake at magnitude 5.8, centered 29 miles southeast of downtown Los Angeles near Chino Hills in San Bernardino County. Ten aftershocks occurred in the next dozen minutes, including three estimated at 3.8.
Los Angeles Fire Department spokesman Brian Humphrey said there were no immediate reports of damage or injury in Los Angeles. San Bernardino County fire dispatch also had no immediate reports of damage.
The quake struck at 11:42 a.m. PDT. Buildings swayed in downtown Los Angeles for several seconds.
Workers quickly evacuated some office buildings.
"It was dramatic. The whole building moved and it lasted for a while," said Los Angeles County sheriff's spokesman Steve Whitmore, who was in the sheriff's suburban Monterey Park headquarters east of Los Angeles.
In Orange County, about 2000 detectives were attending gang conference at a Marriott hotel in Anaheim when a violent jolt shook the main conference room.
Mike Willever, who was at the hotel, said, "First we heard the ceiling shaking, then the chandelier started to shake, then there was a sudden movement of the floor."
Chris Watkins, from San Diego, said he previously felt several earthquakes, but "that was one of the worst ones."
Delegates and guests at a cluster of hotels near the Disneyland resort spilled into the streets immediately after the quake.
The 1994 Northridge earthquake under Los Angeles' San Fernando Valley was magnitude 6.7. It killed 72 people, injured more than 9,000 and caused $25 billion in damage in the metropolitan area.
The damage created by an earthquake depends greatly on where it hits. A 7.1 quake - much stronger than Northridge - hit the Mojave Desert in 1999 but caused only a few injuries and no deaths.
California is one of the world's most seismically active regions. More than 300 faults crisscross the state, which sits atop two of Earth's major tectonic plates, the Pacific and North American plates. About 10,000 quakes each year rattle Southern California alone, although most of them are too small to be felt.
Associated Press Writer Thomas Watkins in Anaheim contributed to this report.

it was nothing really.
of note: a 5.9 is ten times stronger than a 5.8, and a 6.0 is a 100 times stronger.

We have everything up to 3.0 on an almost weekly basis, and you never feel it. It's almost ambient.
This was a little shake and nothing more.
Granted we are WAY overdue for something large, even that will be a fun ride.
Give me a sixty second rollercoaster 'quake over a three-day hurricane any day!! |

We all know you started the seismic waves jumping up and down on the stage so hard during your set!

You have the math wrong. A 5.9 quake is 10 raised to the tenth root of ten times stronger than a 5.8 quake. This is approximately 26% stronger (.2589254). Going from 5.0 to 6.0 is a tenfold increase in power. From 5.0 to 7.0 is 100 times. Think of the magnitude numbers as exponents for the base 10.
Though 26% is a smaller number than the 1000% you are thinking, it is still a trememdous amount of additional energy. It's rare to feel one that is under 4.0 on the scale, but I have when I've been right close to the epicenter. The ones greater than 6 seem to have plenty of power to spare and I've felt them from many miles away. Like that 7.1 quake mentioned in the news article.
