3:36 p.m. June 15, 2004Two earthquakes less than a minute apart and centered far from San Diego County apparently combined to give the county a thorough shaking Tuesday afternoon, according to official monitoring data. There were no immediate reports of damage or injuries. The first quake, centered 56 miles southwest of Imperial Beach off the coast of Baja California, was measured at 5.1 magnitude at 48 seconds past 3:28 p.m., according to preliminary U.S. Geological Survey data. A second quake, initially described as a "light" temblor at 4.7 magnitude on the open-ended Richter scale, was centered in the Mojave Desert seven miles southwest of Edwards Air Force Base at 25 seconds past 3:29 p.m., according to the data. Dogs barked, buildings rattled and residents scurried outside to see what was going on during the quake, which lasted about five seconds.
