*8.6 Quake Possible in Southern California?

A little baby earthquake jolted parts of Southern California tonight.

The 4.4 temblor was centered about 2.2 miles northeast 1 mile north-northeast of Yorba Linda, which is in northeast Orange County, and struck at 11:23 p.m., according to the U.S. Geological Survey.

We did not feel it in our particular neck of the Westside woods, but many of you did:

Folks from San Diego to Castaic reported feeling it.

Earthquake weather? That's the question during this heat wave, right?

No. Caltech seismologist extraordinaire Lucy Jones told reporters earlier this year that there's no such thing as earthquake weather. She said that generations that go through a particularly traumatic temblor attach whatever weather was happening at that time to the concept.

Therefore there have been times in the past when cold, for example, was associated with “earthquake weather.”


Don't be. We're still going to get the Big One someday, rain or shine.

[Added at 11:59 p.m.]: L.A. Fire Department spokesman Matt Spence says no damage or injuries have been reported but that the LAFD is in “Emergency Earthquake Mode,” apparently as a precaution.

There was also a 2.7 aftershock about one minute after the 4.4., two mines north of Yorba Linda, according to the USGS.

The depth of the 4.4 was about 5 miles, according to the Survey.

[Added at 12:39 p.m.]: At 12:14 p.m. Spence stated:

We are now *out* of Earthquake Mode. LAFD City-wide assessment complete. *NO injuries/significant damage reported* All resources returning to quarters & will be rehoused

[Update at 11:26 a.m. Wednesday]: A 4.5 hit at 9:33 a.m. and then a 3.4 at 9:51 a.m., all in the same, Yorba Linda area, according to the USGS.

Last night's biggest quake was upgraded to 4.5, the Survey says.

Experts are now calling this a “swarm” of temblors. It's not clear if this is leading up to something or a series of aftershocks.

[Added at 11:48 a.m.]: The LAPD activated its Department Operations Center as a precaution following this morning's 4.5, Officer Cleon Joseph told the Weekly. The center was “only at level 1,” the lowest level of readiness, he said.
