SAN DIEGO COUNTY, Calif — Did you feel or hear it? Some San Diegans reported they heard a "boom" followed by a sudden jolt Tuesday evening, but it was not an earthquake. According to the U.S. Geological Survey, there was no earthquake in San Diego Tuesday afternoon. In fact, no one knows what it was.
San Diegans across the county posted on social media that they felt the shaking just after 5 p.m.
One woman in the Santee area posted on the Nextdoor app that she was sitting watching television and out of nowhere her house windows rattled.
USGS said sonic booms, which are loud sounds associated with shock waves, are not uncommon in the southern California area.
But there's no word if it had to do with any of the military bases around town either.
