A loud noise was heard across San Diego County Tuesday evening, but it was unclear what caused the boom.

It occurred around 8:15 p.m. and residents, including San Diego Mayor Todd Gloria, took to social media to report hearing the boom.

"Yes, I heard it," Gloria wrote on Twitter. "No, I don't know what it was. I'll share if I get any information."

There were no reports of an earthquake occurring in the region at that time, according to the U.S. Geological Survey.

Camp Pendleton posted on its Facebook page June 3 that artillery units were scheduled to conduct live-fire training from Saturday through Friday and explosive munitions fire was expected between 6 a.m. and midnight each day.

KPBS has created a public safety coverage policy to guide decisions on what stories we prioritize, as well as whose narratives we need to include to tell complete stories that best serve our audiences. This policy was shaped through months of training with the Poynter Institute and feedback from the community. You can read the full policy here.
