UC Berkeley experienced a massive explosion late on the evening of Monday, Sept. 30, 2013, and it resulted in at least one injury, a power outage, and a campus evacuation. The Washington Post reported that the evacuation was campuswide and that a huge fireball shot into the air.
The explosion was reported near Sather Tower shortly before 7:00 pm on Monday evening. Some witnesses were nearby and said the blast had a fireball that shot at least two stories into the air.
"The explosion was about two stories high and as wide as a two-lane street," UC Berkeley spokesman Dan Mogulof told the Associated Press. "We're very fortunate there were no serious injuries."
The cause of the power outage was being investigated, but campus emergency officials did have the entire UC Berkeley campus evacuated due to the explosion. Power has since been restored to most of campus, but one person was hospitalized for minor burns.
Three others received minor burns, but they refused treatment.
About 20 people were trapped in dormitory elevators across campus due to the power outage. They had to be rescued by fire crews.
The Twitter account for the University of California, Berkeley, said that most of Tuesday's classes would be held as scheduled.
It is believed that the explosion may have been caused by an attempted underground copper wire theft on campus last week. There is no word though if all the incidents were related.
