The University of California at Berkeley campus was evacuated after a power outage cancelled evening classes and an explosion that led to one person being hospitalized for minor burns.
The explosion occurred in an underground utility vault outside California Hall as crews were trying to restore power on campus shortly before 7 p.m. Monday. In addition to the one person hospitalized, three others also received minor burns but refused treatment, said UC Berkeley spokesman Dan Mogulof.
"The explosion was about two stories high and as wide as a two-lane street," Mogulof said. "We're very fortunate there were no serious injuries."
The blast may have been caused by an underground copper wire theft at a campus substation last week, Mogulof said. Officials thought they had repaired the damage Sunday.
"It appears that may have caused far greater damage than initially thought," Mogulof said. "It's more extensive."
With many buildings in the dark, fire crews also freed about 20 people stuck in dormitory elevators as a result of the outage that also led to the mandatory evacuation on campus.
