The main objective of our study is to update the FDMs that were developed over a decade ago by the U.S. Geological Survey and California Geological Survey, in which a reference trace was drawn manually, FDMs are fixed-effect models for lateral displacement, displacement on multiple subparallel ruptures is not aggregated, magnitude (M) scaling is linear, and natural logarithm of displacement is assumed to be normally distributed.
