Loud ‘booms’ heard in East County

SAN DIEGO — Residents are reporting a series of loud “booms” in the East County Wednesday afternoon.

FOX 5 started receiving a flood of tweets and Facebook messages about the explosion sounds starting around 3:30 p.m. Most residents said they heard the sounds from Santee, though others reported the booms in El Cajon and as far west as Tierrasanta.

The booms can likely be attributed to Camp Pendleton. The base’s noise advisory site┬álists two different “high explosive munitions” exercises involving mortar and artillery fire for June 20.

The San Diego County Sheriff’s Department said they weren’t aware of anything that would have caused the booms. FOX 5 also placed a call to Marine Corps Air Station Miramar, but so far have not heard back.
