The Valley area apparently escaped with no significant damage from the 6.4 magnitude earthquake that struck near Ridgecrest Thursday morning.

The Los Angeles Police Department, Los Angeles County Sheriff’s Department and Ventura County Sheriff’s Office reported no significant damage in their jurisdictions.

The temblor struck at 10:33 a.m. in the remote Searles Valley area near Ridgecrest, some 125 miles northeast of Los Angeles. It was the largest earthquake centered in Southern California in 20 years.

The Six Flags Magic Mountain theme park had just opened when the quake occurred and all the rides in both Magic Mountain and the adjacent Hurricane Harbor water park were shut down for visual inspections, said Sue Carpenter, a park spokesperson.

“Within 45 minutes we were up and running as normal,” Carpenter said.
