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.
