Hayward residents experienced a shocking incident on the morning of December 11, 2025, when a natural gas explosion jolted the community on East Lewelling Boulevard near I-238. A Pacific Gas and Electric Company (PG&E) natural gas pipeline leak led to a fire and the destruction of a single-family residence, causing serious injuries to three occupants. This calamity unfolded as PG&E responded to the leak, resulting in additional injuries to three PG&E workers on-site addressing the situation.
According to the National Transportation Safety Board's (NTSB) preliminary report, the PG&E distribution system was operating at approximately 49 pounds per square inch gauge when the explosion occurred. The gas main on East Lewelling Boulevard, which had been installed in 1942, sustained damage during roadwork by Mayo Asphalt Milling, which was the catalyst for the subsequent events. A PG&E crew had successfully stopped the flow of gas in the line, but shortly afterward, the explosion razed the residence at the focal point of the disaster.
Aerial coverage by CBS News showed the extensive destruction with debris scattered across the neighborhood as firefighters tackled the blaze and attended to victims. Hoodline's report highlighted the chaos, detailing the smoke and wreckage as "a thick column of smoke towered over the neighborhood" and "Live television footage showed residents being carried from damaged homes." Emergency personnel responded with a three-alarm operation, mobilizing resources to conduct search-and-rescue efforts while preventing the fire from spreading to adjacent properties.
Uncertainty lingered in the immediate aftermath, as officials had not yet confirmed the specific cause of the blast. In the spirit of public safety, local authorities urged residents to exercise caution while the area was being secured and assessed. The Alameda County Fire Department was prompt in issuing updates to the public, as per Hoodline.
