A San Diego earthquake was felt by many San Diegans today. Was the loud noise many heard and felt really a San Diego earthquake? It seems according to the U.S. Geological survey, the noise at 4 this afternoon was really a sonic boom and not a San Diego earthquake.
San Diego 10News.com reports USGS seismologist Robert Dollar told them sonic booms are caused by high speed aircraft. It is possible the alleged San Diego earthquake was noise bouncing off the atmosphere. The sonic boom noise traveled around the county, making everyone think there was a San Diego earthquake.
