Yes, you're not crazy, there was an earthquake, albeit minor, in Riverside County. The 3.3 magnitude quake struck at 11:54 p.m., 5 miles west of Beaumont, according to the United States Geological Survey. About the above map: Withs some funding from the federal stimulus package, the USGS is exploring the world's fastest (and unofficial) newswire, Twitter.

Debris flows from the 2003 Old and Grand Prix fires left 16 people dead, according to a post-Station Fire report released yesterday by the USGS. Perhaps, that's one reason to take note of the debris flow areas marked on multiple maps within the report.

Remember that earthquake we had last week? You know, the 5.4 magnitude that struck just before lunchtime and had tall office buildings swaying on their rollers, grocery stores seeing items topple from shelves to the floor, and the media scrapping all other programming for non-stop post-quake coverage. Yeah, that one. Well, if you felt it, the US Geological Survey wants to know about it.

Did you feel that? Yes you did. That was a 5.4 magnitude earthquake (preliminary reports stated that it was a 5.8 and then 5.6) out of the Chino Hills area that struck at 11:42 a.m., according to the USGS, who considers this to be a "moderate" earthquake. Chino Hills is 29 miles southeast of Downtown Los Angeles.

The Great Southern California ShakeOut was officially announced today where millions of Southern Californians will “Drop, Cover, and Hold On” (register at www.ShakeOut.org) as thousands of emergency responders statewide take part in the largest-ever earthquake response drill called "Golden Guardian." The hypothetical magnitude 7.8 earthquake will rupture the San Andreas Fault at 10 a.m. on November 13.

The media has been reporting various small quakes over the last week. But is that really something to worry about? "It’s not uncommon for Orange County to experience several microquakes every week," Sciencedude Gary Robbins said at the OC Register in a brief about the three recent microquakes in Orange County. His statement goes for all of Southern California -- small quakes happen all the time. A daily viewing of the USGS' recent earthquake map shows this or event better, the agency has gotten hip to Twitter and publishes a feed called "socalquakes." They also publish "Earthquake News," which combines shakes worldwide and headlines.

Hollywood studios are not the ones behind the latest script detailing a massive future earthquake hitting Los Angeles. This time, it's scientists and other quake experts... over 300 of them. Specifically, the U.S. Geological Survey and California Geological Survey have collaborated to write a script, to be released tomorrow to a House subcommittee, "detailing the devastation California would likely face if it were rocked by a monstrous 7.8-magnitude earthquake," according to the Associated Press. The plausible three-minute shaker will play out with results like this:

Yes, that was a 4.2 earthquake you felt or dreamt about at 1:53 a.m. A light earthquake occurred at 1:53:43 AM (PDT) on Tuesday, October 16, 2007. The magnitude 4.2 event occurred 5 km (3 miles) N of Wrightwood, CA. The hypocentral depth is 3 km ( 2 miles). The AP reports that "it was not immediately known if the quake had caused any damage or injuries." We don't mean to nag, but here...

We felt it slightly in the Valley and according to the USGS, a 4.7 Earthquake east of Santa Ana hit at 10:29 a.m.Lake Elsinore, CA - 13 km (8 miles) WNW (298 degrees) Lakeland Village, CA - 15 km (9 miles) NW (314 degrees) Portola Hills, CA - 16 km (10 miles) ENE (70 degrees) Corona, CA - 18 km (11 miles) SSE (148 degrees) Los Angeles Civic Center, CA - 80 km (50 miles)...

It's a full moon and the earth is shaking. Three small quakes within a hundred miles of Los Angeles in the past hour alone, according to the U.S. Geological Survey Web site. Perhaps unscientific -- though seemingly never "gamed" or exagerrated -- is the USGS "shake map" at right. Within 30 minutes of tonight's 3.2 magnitude shaker centered near Granada Hills, over 700 people went to the site to report shaking intensity. Hover over the...
