An earthquake occurred at 6 p.m. Friday evening, June 19, off the coast of Southern California. The USGS website reported the quake as a 4.1 magnitude event with its epicenter 45 miles west-southwest of Oceanside, CA, in the Pacific Ocean. There were no reports of damage or injury; however, train travel was interrupted in San Diego County. Train officials were concerned about possible bluff failures along the train tracks in Del Mar. A train dispatcher of the Metrolink San Diego subdivision directed Coaster train number 661 and Amtrak train number 582 to proceed at restricted speed through the bluff area. Amtrak train 582 incurred a delay of 27 minutes into San Diego. The train order remained in place until shortly after 8 p.m., and three other passenger trains incurred minor delays.
