Frankel Fault Surface

A Frankel Fault Surface is one representation of a Gridded Surface that was created by Arthur Frankel for use in the 1996 and 2002 USGS National Seismic Hazard Maps. See also Earthquake Rupture.

In OpenSHA, the trace and average dip of a Simple Fault are used to create rectangular surfaces where the dip direction of each rectangle is perpendicular to the strike of its local segment. The resulting surface is then gridded (discretized) according to whatever interval is specified.

Compare to a Stirling Fault Surface.
