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.

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.
