Firefighters investigate reports of explosion near Scripps Pier

LA JOLLA, Calif. – An explosion was heard in La Jolla near Scripps Institution of Oceanography buildings Monday evening.

San Diego firefighters went to the 8300 block of Discovery Way in La Jolla just before 9 p.m. They received calls about smoke after hearing an explosion.

The battery for an acoustic sonar sensor used for studying whales short-circuited, releasing some smoke and set off alarms, a fire official told FOX 5. They called HAZMAT crews to investigate as an abundance of caution.

No injuries were reported.
