People in Pasadena and other parts of Southern California were rocked out of bed early this morning by a magnitude-4.4 earthquake whose epicenter was in San Bernardino County, the Pasadena Star News is reporting.

The paper said the quake struck at 1:35 a.m. at a depth of just over 3 miles, according to the U.S. Geological Survey. The epicenter was 3 miles north-northwest of Fontana and 4 miles west-northwest of Rialto, said USGS seismologist Valerie Thomas.

There were no immediate reports of injuries or damage. Just a heck of a good jolt early in the morning to know you are in California, I guess.

"It felt like somebody ran into our building,'' said Sgt. Chris Hice of the Rialto Police Department told the newspaper. Hice said the only report of damage in the city 25 minutes after the earthquake was of some broken glass at a school.
