Earthquakes

Earthquake overview

During a major earthquake, you may experience a shaking that starts out to be gentle and within a second or two grows violent and knocks you off your feet. You may be jarred first by a violent jolt -- as though your building was hit by a truck. A second or two later you’ll feel the shaking and, as in the first example, you will find it very difficult (if not impossible) to move from one room to another.
