A significant rupture in a gas pipeline occurred in California’s valley late Saturday, compelling locals to remain indoors and leading to the closure of a major highway during a peak holiday travel period.
The Los Angeles County Fire Department was alerted to the incident on Old Ridge Route in Castaic shortly after 4:20 p.m. PST. This prompted a shelter-in-place directive impacting approximately 14,000 residents.
Footage captured the dramatic scene, showing thick clouds of smoke and visible ground disturbance from the pipeline burst.
Initial concerns suggested that the leak might have been triggered by a landslide or storm-related soil instability. However, LA Fire officials later indicated that excessive pressure within the pipeline was likely responsible, although investigations are ongoing to determine the precise cause.
LAFD Captain Brian Knight informed local ABC station KABC that while a landslide has been ruled out, any tremors felt by residents were due to the intense pressure from the leak.
Los Angeles Mayor Karen Bass addressed the situation, noting, “We are closely monitoring a gas leak in Castaic, Los Angeles County. Some residents may notice the natural gas odor in the air.”
‘LAFD and L.A. County report that this is not harmful and poses no immediate danger to City residents.’
Bass added that LAFD Hazardous Materials personnel were monitoring air quality in the impacted areas.
