Texas Tech University's campus will be closed the rest of this week after a manhole explosion apparently triggered a series of fires around campus.

A series of fires and a manhole explosion led officials to shut down the campus and send students home early for spring break.

Texas Tech University sent students on an early spring break after spurts of green flames shot out from manholes on campus on Wednesday night. The source was an explosion at a substation that caused widespread outages across campus and the university's Health Sciences Center.
