SAN DIEGO (KGTV) -- People throughout San Diego County are searching for answers after hearing a mysterious boom Wednesday afternoon.

Dozens of San Diego Residents in La Jolla and Del Mar took to Twitter after hearing the noise before 12:45 p.m.

"Felt it in La Jolla / Windansea - even my dogs started barking," one Twitter user said, referring to the noise.

10News also received calls from people in Ocean Beach and Pacific Beach.

Several people wondered whether or not an earthquake could be to blame, but according to the United States Geological Survey, the nearest earthquake was a 2.9 magnitude near Corona reported at 4:16 a.m. Wednesday.

USGS' website states that, "reports of a bang are a clue that it's a sonic boom, but not an ironclad indicator since shallow earthquakes often sound like booms or bangs."

10News has reached out to military officials to see whether or not military exercises may have caused the boom.

The Marine Corps, however, did send a statement that reads, in part: "While we are aware of media reports of a possible sonic boom, no 3rd MAW units have reported one in San Diego air space. We will notify you if we receive any further information."
