Short answer
To earthquake-proof your plumbing, strap your water heater with two seismic straps, use flexible gas and water connectors, know how to shut off your water and gas, and store drinking water. After a quake, check for leaks, and do not use water from a cracked line until it is inspected.

Water heater
California requires seismic straps. A falling heater can break gas and water lines.
Connectors
Flexible connectors handle movement better than rigid pipe.
