First Map Product 1:2 Million of Seven States

State and Federal Emergency Management Agency representatives supported the approach of first, preparing small-scale regional hazard maps (1:2,000,000-scale) to link State Emergency Management Agency (SEMA) groups with CUSEC Geologists and to compile and assemble geologic information on near surface sediments from CUSEC states into a common Geographic Information System (GIS) through coordination of all states' efforts. This first product, completed in 1995, was a 1:2,000,000-scale or 1 inch equals about 32 miles, general seismic hazard map for the CUSEC seven-state region. A later version was producted in 1999 with the U.S. Geological Survey (right).

One to 250,000 Scale (1×2 degree quadrangles) in Eight States

The second map products were intermediate-scale (1:250,000-scale or 1 inch equals about 4 miles), soil site classification maps which were used by the state emergency exercise planners to produce detailed earthquake damage scenarios used in State earthquake exercises. These maps are eleven 1×2 degree quadrangles (and parts of 2 others) which  encompass the entire high risk area of the New Madrid Seismic Zone (Belleville, Paducah, Rolla, Vincennes, Evansville, Dyersburg, St. Louis, Poplar Bluff, Blytheville, Cincinnati, and Memphis quadrangles and parts of Hellina and Tupelo). Each map covers an area of about 7,600 square miles. These maps of soil amplification are critical in producing realistic estimates of damage when using the Federal Emergency Management Agency's Earthquake Loss Estimation Program, HAZUS.

One to 24,000 Scale Maps of City Areas

These soil amplification maps, at a scale of 1:24,000 (1 inch = 2,000 feet), were produced for FEMA's Earthquake Loss Estimation Program (HAZUS) for use by the communities to estimate and mitigate their earthquake losses. The soil amplification maps were based on geologic maps, at a scale of 1:24,000, that were specifically made for this project or used existing maps that were modified with new data.
