Context

Background

On the evening of March 12, 2025, an underground fire and explosion at a power substation rocked the Engineering Key area of Texas Tech University's campus in Lubbock. CNN reported that students saw green flames erupting from manholes and heard three loud booms; officials later attributed the unusual green color to burning copper wiring. Lubbock Fire Rescue had first been called for a reported gas leak just after 7 p.m. CDT before flames were found shooting from manholes. KCBD reported that approximately 7,300 students were displaced by the power outage, with 40% of campus losing electricity. The university closed for Thursday and Friday (March 13-14), with CBS Texas confirming that spring break was moved up. The State Fire Marshal's Office took over the investigation. No injuries were reported. KCBD interviewed students who described the confusion during the evacuation. TPR and Houston Public Media provided statewide coverage of the dramatic incident.
Analysis

Key Findings

7,300 students were displaced by the power outage caused by a single substation explosion, illustrating the vulnerability of aging campus electrical infrastructure
Emergency crews were first called for a reported gas leak just after 7 p.m. CDT; the cause was reclassified across the evening (an early campus alert referenced a substation, a later update a manhole explosion), showing how rapidly evolving situations complicate alert accuracy
Green flames from manholes and loud explosions created a dramatic scene that students documented on social media
Outcome
No injuries were reported. The State Fire Marshal's Office investigated. The campus closed Thursday-Friday, March 13-14, with spring break starting early. Power was restored after 50 meters of electrical infrastructure were repaired.
