Here in the Pacific Northwest our biggest natural disaster concern may very well be earthquakes. As part of our preparation in the event of an earthquake, it would be wise to do a walk-through of our homes. Are large and heavy bookshelves strapped or bolted to the wall? Is the water heater strapped in to prevent not only damage to it but also water damage to other things? Hardware kits for this are readily available at any hardware store. For the water heater they average just under $15. For bookshelves you can get a kit that will secure 2 or 3 pieces of furniture for around $5. For just a little money and a few minutes of your time you can make your home more secure for yourself and your loved ones in the event of an emergency.
