Earthquakes of the Central United States, 1795-2002 Construction of the earthquake catalog for an outreach map

By Russell L. Wheeler

U.S. Geological Survey Open-File Report 03-232

 

Version 1.0

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. 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. The large-format outreach map will be published as an I-Map in a few months.
