Residents of San Diego are attempting to figure out just what shook them and made a loud noise Thursday, particularly after the U.S. Geological Survey said there weren't any earthquakes registered in the area.
The event happened at 11:33 a.m. PDT Thursday. Emergency dispatch centers received thousands of phone calls reporting the event, but it remains a mystery.
The USGS tracks earthquakes around the world; but on Thursday, there hadn't been any temblors recorded anywhere near San Diego. The day was fairly calm for Southern Californians, seismically speaking. Only three events were recorded in the central part of the state.
Some scientists have suggested the boom could have been the result of a meteorite that hit the atmosphere and disintegrated above the city, similar—but not nearly as destructive—to what happened over Cheylabinsk, Russia, in February of 2013.
Earth is currently exiting a period of heightened meteor activity caused by passing through the leftover debris field from Halley's Comet.
