A magnitude 3.3 earthquake hit Wednesday morning just outside Redding, California.
The US Geological Survey reports the epicenter of the quake, which struck at 11:30 a.m., was about 2.5 miles northwest of Redding, near the intersection of Keswick Dam Road and Quartz Hill Road.
"It was a BOOM! I thought a truck hit the building," said JPR classical music host and Northern California Program Co-ordinator Valerie Ing. Ing was in her office at the JPR studio at the Cascade Theater in downtown Redding. Others further from the epicenter report on Facebook they felt a shaking that rattled windows.
Jennifer Cogle, dispatch supervisor at SHASCOM 9-1-1, said that as of 12:20 p.m., there had been no reports of injuries or damage.
The quake was centered about half a mile from the Keswick Dam on the Sacramento River. Don Bader at the Bureau of Reclamation, which operates Keswick Dam and nearby Shasta Dam, told JPR crews were out inspecting both dams to assess for any damage. He noted that none of the dam power generators went offline. He said the machines are designed to shut down in a serious quake.
