How to measure an earthquake

rebecca's picture
the key is this:
anything less than a 4, you're not going to feel unless you are standing pretty much on top of the epicenter and there is nothing going on around you.
4's - sometimes, but you need to be fairly close, and you can easily mistake them for something else - train going by, big trucks, etc;
5's - you can definitely feel, but they don't cause much damage;
6's - you really feel, and they cause some property damage, but not enough to have a lot of people getting hurt;
7's - you're ducking for cover, strong enough that roads and bridges start falling apart, houses come off their foundations, and lots of people end up hurt.
