A 5.7 earthquake struck tonight, moments ago, at 9:26 pm, five miles from Ocotillo, CA, which is about 22 miles from El Centro, CA and about 27 miles from Mexicali.  Click here for more information from the U.S. Geological Survey.

My wife felt it here in Santa Ana.

Will there be any aftershocks? Here is what the California Institute of Technology’s Seismological Laboratory is reporting:

STRONG AFTERSHOCKS (Magnitude 5 and larger) –
At this time (immediately after the mainshock) the probability of a strong and possibly damaging aftershock IN THE NEXT 7 DAYS is approximately 40 PERCENT.

EARTHQUAKES LARGER THAN THE MAINSHOCK –
Most likely, the recent mainshock will be the largest in the sequence. However, there is a small chance (APPROXIMATELY 5 TO 10 PERCENT) of an earthquake equal to or larger than this mainshock in the next 7 days.

WEAK AFTERSHOCKS (Magnitude 3 to 5) –
In addition, approximately 15 to 50 SMALL AFTERSHOCKS are expected in the same 7-DAY PERIOD and may be felt locally.
