San Diegans are once again reporting they heard or felt a mysterious "boom." How about you?
Some are saying it's an earthquake that sent shockwaves through their neighborhood and rattled their homes, but the U.S. Geological Survey said the closest earthquake to San Diego shook 350 miles away in Bishop, CA.
The U.S. Marine Corps confirmed they're conducting explosive munitions training on base Monday between 6 a.m. and midnight, but couldn't say if the "booms" heard and felt between around 3 and 4:30 p.m. were theirs.
Here's some reaction from around town:

San Diegans all over the county also reported a similar shaking Friday, but no one has been able to get to the bottom of that one either. There was one time last year Phil Mickelson got a little carried away testing drivers, according to a tweet from his, so we'll see if he takes credit again.
