Surface ruptures associated with these earthquakes are in a variety of geologic media ranging from valley alluvium to colluvium to bedrock, and occur at various positions relative to mountain fronts, all along the same rupture segments. Ruptures occurred both as continuous, interconnected segments and as discrete separated segments. Such characteristics indicate several pitfalls in the use of empirical fault-length data to estimate earthquake magnitudes for seismic-design purposes. The common practice of using well-defined surface fault segments instead of the entire length of the fault zone or fault system for estimating maximum earthquakes can lead to underestimating earthquake potential.
