While most earthquakes are so small they are rarely felt, modern technology records between 12,000 to 14,000 earthquakes each year, the larger ones claiming thousands of lives in a matter of seconds. Amazingly, earthquakes are also occurring in such unlikely places as the Texas Panhandle, Idaho, Colorado, New York and the Mississippi Valley. We can't prevent them, but with a little forward thinking, we can do everything possible to survive them.
The first sign: Earthquakes often begin with a short, quick pre-shock that rattles windows and feels like someone just bumped into your chair. Normal reaction is to stop, look around and see what's happening. But what you do or don't do in those few seconds could save your life.
Do -- train yourself to be sensitive to movement under your feet. If the floor moves, it's a pre-shock. Plan the safest place to be during the quake, (preferably an area with close walls like the bathroom or a stairwell) and your escape route out of the building. Always keep hallways and doorways clear of boxes, suitcases, toys, etc. As soon as you are outside, immediately turn the gas off to prevent fires.
Don't -- get in an elevator! Earthquakes cut power as well as change the door alignment and you may not be able to get out.
Don't -- go back inside damaged buildings after the quake. It's not over! Aftershocks begin in as little as thirty seconds and can be as strong or stronger than the initial quake.
