Land Movement Likely Triggered Castaic Gas Line Break: SoCalGas Reports
Recent investigations indicate that significant land movement may have caused a natural gas pipeline rupture in Castaic, California. This incident occurred on Saturday, just before 4:30 p.m., affecting a major 34-inch transmission line near Ridge Route Road and the 5 Freeway.
Details of the Castaic Gas Line Break
SoCalGas confirmed that the rupture resulted in a substantial leak of natural gas. Eyewitness accounts noted visible dirt and debris being kicked up as the gas was released under extreme pressure. Although emergency crews managed to isolate the damaged section and stop the leak that same night, many residents in nearby communities reported smelling gas.
Impact on Local Communities

- Less than five non-residential customers experienced natural gas outages due to the rupture.
- Fire officials declared no immediate health risk to the surrounding area.
Previous Incidents of Land Movement
The region around Castaic is known for its susceptibility to landslides, which has previously affected traffic on the 5 Freeway. Notable incidents include:
| Date | Incident Details |
|---|---|
| January 14, 2023 | A severe slide at the top of the Castaic Grade prompted a long-term stabilization project, reducing northbound lanes. |
| March 30, 2023 | A landslide beneath the southbound lanes caused several traffic lanes to collapse, necessitating stabilization with metal girders. |
Future Precautions
