An earthquake or seismic shut-off valve automatically shuts off your natural gas service when an earthquake of a sufficient magnitude occurs at your home’s location. These valves can be purchased and installed through independent suppliers and contractors.

If an earthquake or other significant event causes your seismic shut-off valve to close, contact a licensed, qualified contractor to reset the valve, verify that no gas leaks exist, and perform a safety check of your gas appliances before they’re placed back into operation.
