A minor earthquake shook Southern California before dawn Tuesday morning.

The quake was centered about 10 miles east of downtown Los Angeles and registered a 4.4 magnitude, according to the U.S. Geological Survey.

"It was a shake, but not bad. Our inmates slept through it and we had a few calls, but not as many as you would think," Pico Rivera sheriff's station Sgt. Jacqueline Sanchez said.

There were no immediate reports of serious injuries or damage. Still, the quake was reportedly felt as far west as the state's coast.
