Abstract

This report describes construction of a list of Central U.S. earthquakes to be shown on a large-format map that is targeted for a non-technical audience. The map shows the locations and sizes of historical earthquakes of magnitude 3.0 or larger over the most seismically active part of the central U.S., including the New Madrid seismic zone. The map shows more than one-half million square kilometers and parts or all of ten States. No existing earthquake catalog had provided current, uniform coverage down to magnitude 3.0, so one had to be made. Consultation with State geological surveys insured compatibility with earthquake lists maintained by them, thereby allowing the surveys and the map to present consistent information to the public.
