Online_Linkage: http://quake.geo.berkeley.edu/anss/catalog-search.html Process_Step: Process_Description: The second method employed polynomial splines of weighted control points to calculate the location of the slab surface. A 10-minute grid was constructed from the geo-referenced control points and contoured using the GMT Surface script (Wessel and Smith, 1998) which interpolates and grids clustered noisy 3D data using Green's functions for splines in tension to reduce artifacts (Wessel and Bercovici, 1998). The computer-generated version was partly intended to serve as a check for bias in the hand-generated version. Although it replicates the general shape of the hand-contoured version, it also generates obvious distortions owing primarily to the uneven distribution of data points. Therefore, we constructed a third version derived from the GMT contours that smoothes out these distortions to provide a simplified contour map of the slab suitable for investigations of strain, stress, ETS, and other processes associated with the subduction boundary which require a simpler surface to model such phenomena.
