Document Summary
Earthquake- motion or trembling of the ground caused by the sudden displacement of a rock. The toll of earthquakes: the consequences of an earthquake depend on, magnitude, depth, direction of fault, distance from populated areas, nature of the local earth materials, engineering and construction practices. Earthquake introduction: result from the rupture of rocks along a fault, energy is released in the form of seismic waves, mapped according to the epicenter, the is directly below the epicenter, measured by seismographs, compared based on, magnitude. Earthquake processes: earthquakes commonly occur at or near plate boundaries, plate boundaries may contain faults.
