SAN DIEGO – Some sort of loud boom was heard — and felt — around San Diego County Monday. Many people took to social media wondering what happened.
Several people told Fox 5 they heard the boom and also felt their homes shake around 12:30 p.m. Monday.
US Geological Survey did not have any records of a major earthquake in the county around the time of the “boom.”
According to the Times of San Diego, a quarry blast in Bonita felt like a “small earthquake.” The epicenter was listed as 4 miles southeast of Bonita and 6 miles east of Chula Vista.
