Dozens of aftershocks rattled California on Saturday in the wake of the 5.1-magnitude earthquake which struck a Los Angeles suburb Friday night.

"There were no reports of any injuries, but (there was) some pretty substantial damage to some stores and buildings. There were some water main breaks, and we've got flooded streets in northern Orange County." (Via KABC)

The 5.1 quake hit the Los Angeles suburb of La Habra at about 9 p.m. Friday. The shaking caused some minor damage but no injuries, although several dozen people had to evacuate their homes over structural concerns. (Via CBS)

In the aftermath of Friday's quake, the California Institute of Technology's earthquake data center recorded more than 100 aftershocks. Most of those didn't register over 2 on the Richter scale.

The notable exception was a 4.1-magnitude quake which hit Rowland Heights at 2:32 p.m. Saturday. The Los Angeles Times reported the quake was "felt across a large area of Southern California," but said  no injuries or damages have been reported as a result of that quake.

And a smaller tremor barged in on a press conference from Caltech geologists about the earthquakes.

"And now we're having an aftershock," said one of the geologists during the press conference. (Via KCBS)

But the good news is that the worst of the quakes is probably over. A geophysicist for the U.S. Geological Survey told the San Jose Mercury News California's seismic activity looks to be subsiding for the moment.

"This is fairly typical aftershock activity for an event this size. ... We have been saying there is about a 5 percent chance of a larger earthquake to come. ... That likelihood is decaying very rapidly."

March has been a rough month for California in geological terms; last week a 4.4-magnitude earthquake near Encino shook up the state and rattled some local news anchors. (Via KTLA)
