Firefighters were deployed through Highland Park tonight after residents reported hearing what sound liked a large explosion that sent car alarms blaring and was felt at a nearby fire station. There have been no reports of injuries or signs of damage in connection with the large boom, which was reported shortly after 8 PM, said Brian Humphrey, a spokeswoman with the Los Angeles Fire Department. The initial reports indicated that the source of the sound came from Avenue 52 and Monte Vista Street, he said. “The firefighters [at station No. 12] felt it – and they are six-tenths of a mile a way,” he said.
Firefighters searching the neighborhood for possible damage were approached by residents curious as to what was the source of the boom. On Twitter, meanwhile, Highland Park residents were also trying to figure out what happened. “The BOOM remains a mystery,” said HLP90042 “Glad it wasn’t a gas explosion. Centralized around 5200 block 90042 rules out sonic boom. But it WAS crazy loud.“
