This article about the Los Angles earthquake today was updated at 1:22 pm.
In the midst of typing a news story, the monitor, floor, and keyboard shook here in Pasadena due to an earthquake. It felt like a 5.0 here, was 5.8 (corrected to 5.4) earthquake centered in Chino Hills. Some phone service is out, power is fine and buildings in Chino Hills appear fine. It was felt as far away as Orange County and Nevada.
The earthquake was apparently associated with the Whittier fault, east of the Whitter Hills Narrows fault.
The Whittier fault is active fault in the Los Angeles region. Caltech in processing information.
5.4 is classified as a moderate earthquake.
We are not evacuating. We are preparing for after shocks. If you want to hear our shocking news check out out twittering. http://twitter.com/MobiWriter
