Areal sources are based on historical [[seismicity]] and are most commonly used in areas that do not have known faults or to account for background seismicity. Areal sources are used to model the spatial distribution of seismicity in three dimensions, an area in map view and a depth. Subduction zones can also be modeled as areal sources by dividing out those earthquakes that occurred on the interface or the intraslab.

Areal sources are based on historical seismicity and are most commonly used in areas that do not have known faults or to account for background seismicity. Areal sources are used to model the spatial distribution of seismicity in three dimensions, an area in map view and a depth. Subduction zones can also be modeled as areal sources by dividing out those earthquakes that occurred on the interface or the intraslab.
