Seismic evaluation criteria

A guideline for determining which faults or seismic sources need to be assigned MCE's. For high hazard structures, faults with Holocene or latest Pleistocene displacement are included and probabilistic assessments are based on an annual probability of occurrence of 2 x 10-5. For significant hazard structures, faults with Holocene displacement are included and probabilistic assessments are based on an annual probability of occurrence of 1 x 10-4.
