ShakeAlert is the USGS earthquake early-warning system for California — it can give you seconds of warning before the shaking reaches your home. Enable it in your phone's Emergency Alerts, or install the free MyShake app. On your end, Cabrillo makes sure the physical side is ready: a seismic gas-shutoff valve, a strapped water heater, and a main water shutoff you can actually find in the dark.
Ask about seismic gas safetyMany San Francisco homes built before 1960 still don't. An earthquake-actuated valve closes your gas line the moment the ground shakes hard enough — quietly helping prevent fires and leaks while you get everyone to safety.
Ask about gas-line safetyCalifornia requires water heaters to be braced to the wall studs so they can't topple, tear a gas or water line, or cut off your emergency water supply in a quake. Two code-compliant straps are a small, fast upgrade.

Explore leak protectionSan Francisco's older homes often hide galvanized and decades-old piping that fails with little warning. Knowing its condition turns a future emergency into a planned, on-your-terms upgrade.
