     A mysterious boom that sent worried reverberations across San Diego County almost exactly two years ago was caused by a military aircraft, U.S. Navy officials told the Los Angeles Times.

    On Wednesday, Navy Cmdr. Kevin Stephens said in 2012, an aircraft flew faster than the speed of sound, causing a sonic boom so powerful that “pretty much all of San Diego felt it,” the Times reported.

    The explanation comes after similar rumblings were felt throughout Long Beach and north Orange County Wednesday afternoon.

    Navy officials said the boom was a part of an exercise with USS Ronald Reagan aircraft carrier, which is training about 50 miles off the coast.

    Like in 2012, many people took to social media to ask if what they felt was an earthquake. The U.S. Geological Survey reported no tectonic activity in both situations.

    In the case of the mysterious San Diego sonic boom, reports of shaking came from La Mesa, University City, Point Loma, Paradise Hills and La Jolla.
