Reinhard, earth quakes really don't effect whether there are gas lines or not. Virtually all cities have utilities run through piping in tunnels built under the streets. The propane or natural gas tanks you would see out in the country are due to a house being too rural to have the underground utilities run. Typically electrical and phone lines will be run on power lines first. Often gas will be delivered to a tank in the yard and sewage will be handled by a septic tank system.
