Earthquakes can be deadly - especially to those who don't know how to behave when the shaking starts.

Here are 9 dumb mistakes that increase the risk of injury or death - and what to do instead, according to the Federal Emergency Management Agency (FEMA).

What's going on outside? Best to leave that to your imagination. During an earthquake it's a big mistake to stand next to a window, under a big mirror or a heavy lighting fixture, or next to a wall.

Anything heavy or sharp that could fall on you could be deadly.

Outside isn't safer than inside, if you stand next to power lines, streetlights, buildings, etc. The greatest danger exists directly outside buildings.

Many of the 120 fatalities resulting from a major quake in 1933 occurred when people ran outside only to be killed by falling debris from collapsing walls.

Research has shown that most injuries occur when people inside buildings rush to move to another location inside the building or outside. Better to stay put until the shaking stops.

If you're in bed when the shaking starts, stay there, say experts. Hold on, and protect your head with a pillow. Only exception? If your bed is under a heavy light fixture that might fall, move someplace safe.

If you need to get out of the building, take the stairs. If the quake KO's the power in your area, you might get trapped inside the building.

If you're in your car when the quake hits, the last thing you want to do is drive over a bridge or ramp that might have been damaged. Stop your car, and stay inside - making sure not to stop under a tree, overpass, or utility wires - or near a building.

Trapped in debris? Maybe you could use a smoke. But hold off. If there's a gas leak, lighting a match could cause an explosion.

Think yelling is the best way to attract rescuers' attention if you're trapped inside a building? Think again. Shouting can cause you to inhale dangerous amounts of dust. Better to tap on a pipe or wall - or blow a whistle, if one happens to be handy.
