Campus officials say power has been restored to most of the University of California, Berkeley, the morning after an explosion left one person hospitalized for minor burns.
The school's Twitter feed announced early Tuesday that most classes would meet as scheduled.
Eleven buildings remain without power and classes in those buildings are canceled.
The explosion occurred in an underground utility vault outside California Hall as crews were trying to restore power following an outage before 7 p.m. Monday. Officials say in addition to the one person hospitalized, three others also received minor burns but refused treatment.
Spokesman Dan Mogulof says the blast may have been caused by an underground copper wire theft at a campus substation last week.
Video uploaded on YouTube showed what the explosion looked like.
