Abstract: This report presents comparisons between four new fault displacement amplitude prediction models that were developed through the Fault Displacement Hazard Initiative (FDHI) Project. The comparisons focus on displacements occurring on principal surface ruptures. Three previously published principal fault displacement models commonly used in engineering practice are also included in the comparison with the new models. The new Fault Displacement Models (FDMs) are a significant improvement over existing models in several ways.
