Two firefighters and two civilians suffered minor injuries Saturday after an electric explosion at the Old World Village's Oktoberfest celebration in Huntington Beach, California, authorities said.
About 15-20 minutes before the explosions, someone called the fire department after lights at the event began flickering. A four-person crew responded, Huntington Beach Fire Department Chief Jeff Lopez said, and went to investigate an underground vault.
When they opened the vault, there was a first explosion, the HBFD said. Then, there were two more explosions, sending flames shooting high into the air.
Firefighters called for help from the fire crews at around 8:19 p.m., the HBPD said.
