The power has been restored after authorities at Texas Tech University said an explosion inside a maintenance hole set off fires and power outages on the campus, leading school officials to issue evacuation orders for several buildings and cancel classes for the rest of the week.

At 8:42 p.m., an updated alert said that an explosion at a substation was the cause of the power outages; however, at 9:42 p.m., another alert from the Texas Tech Police Department said that an explosion at a manhole was affecting multiple locations on campus and causing widespread power outages.
