A 3.9 magnitude earthquake strikes near Lake Elsinore

A 3.9 magnitude earthquake struck just northwest of Lake Elsinore at 9:39 a.m. Thursday.

No damage was immediately reported and given the size of the quake isn't expected.

An alert was not sent by the U.S. Geological Survey’s earthquake early warning system to cell phones in the area as the shaking was not strong enough.

This is the second mild quake to rattle Southern California in the past few days. The other, a 4.4 magnitude temblor, hit on Monday and was centered beneath a highly populated area of Los Angeles near Highland Park. It generated a bit of worry given that it appears to have come from an area that's capable of producing a quake that could be more destructive and deadly than what we would see from the San Andreas.

Two aftershocks followed within a half hour of the initial event. One was a magnitude 3.0 and the other a magnitude 1.9.

There's a 5% chance that a larger quake could hit in the coming days, which is the standard forecast after any quake. However, that likelihood will decrease as time goes on.
