Authorities at Texas Tech University say 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

An underground explosion on the Texas Tech campus, with neon green substance, has forced Texas Tech University to close campus ahead of spring break.

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.
