What is a seismic zone, or seismic hazard zone?

A seismic zone could be one of three things:

  1. A region on a map in which a common level of seismic design is required. This concept is becoming obsolete.
  2. An area of seismicity probably sharing a common cause. Example: "The New Madrid Seismic Zone."
  3. A region on a map for which a common areal rate of seismicity is assumed for the purpose of calculating probabilistic ground motions.
