The epicenter
is only the point on the surface above the location where the fault
begins the slip which generates the earthquake. The epicenter is not
synonymous with “ground zero.” The fault rupture can be tens of miles
long and waves are generated along the entire length of the fault. Thus,
predictions of ground shaking intensities are not based on distances
from possible epicenters, but on distances from known faults, or segments
of faults, on which large earthquakes are anticipated. For more information
on how distance and directivity affect shaking intensity, click
