An understanding of the rock units, stratigraphy, and geologic structure of a region, consistent with the global tectonic setting, needs to be developed to characterize the nature of the existing faults and potential seismic sources of a region. An experienced geologist should assess and summarize the known geologic and faulting conditions found in an available geologic literature, maps, and imagery. When geologic documentation is sparse or requires clarification, detailed surface and aerial reconnaissance of the region should be conducted.
