Definition
Programs that issue bulletins when conditions are such that an earthquake is thought possible in a particular area during a particular time frame. Earthquake advisories may also be issued following an earthquake that inform the public of the epicenter and magnitude of the quake, areas that have been affected and the extent of the damage as currently understood; warn people of the probability of aftershocks; remind people of the steps they can take to evaluate the safety of their current surroundings; and suggest precautions that people should take when leaving their homes. An earthquake is the sudden motion or trembling of the ground produced by abrupt displacement of rock masses, usually within the upper 10 to 20 miles of the earth.
