The State : Quake Shakes Inland Empire

A rolling earthquake shook portions of the Inland Empire region of Southern California, but there were no immediate reports of damage or injury, authorities said. The quake was felt in the Ontario area as well as in San Bernardino, Fontana and Riverside, 50 miles east of Los Angeles. “We thought someone had hit the building. We only got about two or three calls on it,” said dispatcher Teresa Paniagua of the Fontana Police Department. None of the callers reported injuries or damage, she said. The quake was centered about five miles east-southeast of Ontario and measured 3.4 on the Richter scale, officials at Caltech in Pasadena said.
