Dive Brief:

• An explosion followed a power outage on UC Berkeley's campus and one person was hospitalized.
• The explosion occurred in an electrical vault as crews attempted to restore power and may have been caused by an attempted underground copper wire theft last week.
• Officials said the cause of the incidents had not been officially determined.

Dive Insight:

At least one person was injured in the explosion, which also prompted a mandatory evacuation. Theft of copper is estimated to cost about $1 billion a year. The metal is worth about $3 per pound and makes a tempting target for thieves.
