Abstract
An updated version of the catalog that was used for the current national probabilistic seismic-hazard maps would suffice for preduction of large-scale hazard maps of the Memphis urban area. Deaggregation maps provide guidance as to the area that a catalog for calculating Memphis hazard should cover. For the future, the Nuttli and local netword catalogs could be examined for earthquakes nor presenly included in the cataloge. Additional work on the aftershock removal might reduce hazard uncertainty. Graphs of decadal and annual earthquake rates suggest completeness at and above magnitude 3 for the last three or four decades. Any additional work on completeness should consider the effects of rapid, local population changes during the Nation's westward expansion.
