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.

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

An underground explosion on the Texas Tech campus, with neon green substance, has forced Texas Tech University to close campus ahead of spring break.
