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.

The explosion came from a manhole on campus near a substation, causing power outages in the area and at the Texas Tech Health Sciences Center, officials said.

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