I discovered a leak coming from the plastic drain valve at the bottom
of the gas water heater. I tightened the valve up but it keeps
dripping. Can that fitting be replaced? I think this happened from an
earthquake last week. It was a sudden jolt and may have broken
something internally.

I've never seen a plastic drain valve on a water heater. However, all
drain valves should be replaceable; it should just unscrew from a threaded
hole. You'll need to shut off the gas to it, attach a hose, and drain it
first. Use care when unscrewing the valve; it's probably cracked.

Take it to a plumbing supply store or home center and get a replacement.
Use teflon tape on the replacement to help it seal.
