Mississippi pipeline explosions linked to unrepaired gas leaks
(UI) — Two natural gas explosions in Jackson, Mississippi, were caused by leaks that had been previously identified but not repaired, according to findings from the National Transportation Safety Board.
The explosions, which occurred days apart in January 2024, destroyed multiple homes, killed one person and injured another.
Investigators found that soil movement loosened underground pipe connections, allowing gas to escape and migrate into nearby homes where it accumulated and ignited.
Atmos Energy had detected the leaks at least eight weeks before the explosions but classified them as “nonhazardous” and did not repair them.
The NTSB said the company also lacked procedures to re-evaluate known leaks in areas with shifting soil conditions, allowing the risk to escalate over time.
The investigation found additional gaps in safety practices, including incomplete service line records and limited risk identification for aging infrastructure.
Residents had reported smelling gas prior to the explosions, but investigators said clearer public guidance could have prompted faster evacuation and emergency response.
The NTSB issued eight safety recommendations to Atmos, including replacing vulnerable pipe connections, improving leak monitoring and strengthening public safety communication.
