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.

LP&L crews restored power to most on-campus buildings after multiple explosions and power outages on the Texas Tech University campus, but about 40% of on-campus buildings still don't have power as the investigation into the cause continues.

Texas Tech and Lubbock Fire Rescue officials were confirming an ongoing evacuation near the campus' engineering key as well as outages across the Tech and Texas Tech Health Sciences Center campuses following several fires and a power substation explosion Wednesday evening.
