A day after the incident in which green flames could be seen coming out of manholes, 40% of the university in Lubbock remains without power.

An explosion on the Texas Tech University campus in Lubbock set off fires and power outages Wednesday, leading school officials to issue evacuation orders for several buildings and cancel classes for the rest of the week.

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