and the very real desire to double check stuff....here's a list of things off the top of my head to check.

- Make sure the water heater is ok (no leaks- water or gas)
- Make sure you can't smell the natural gas in your kitchen, laundry room/facility, or outside where the gas comes into your home (assuming that you have gas)
- Check under all your water faucets (kitchen, bathroom, laundry room) for water drips
- Check the toilet(s) to see if there are any leaks or anything. Ensure that the tank has the "correct" amount of water in it (basically make sure it doesn't have a crack)
- Check to see if you have a dramatic loss in water pressure. Also see if the ground outside is boggy or whatever (basically ensuring no water pipe break underground).
-Check to see if there are any cracks in walls/pillars big enough to put your pinky finger in...especially if they are deep enough to fit into the first knuckle. One or two spiderweb cracks are completely different from finger width cracks.
-Check for downed power lines.

Of course, the solution to those are all dramaticaly different. For gas/electrical...you call immediately. Leaks you call a plumber before something's damaged. Broken toilet tank gets you a trip to Home Depot. Cracked pillars gets you a call to a structural guy.

You'll be ok.
