Beginning in 1998, the USGS initiated projects to address
high-resolution seismic hazard assessments in at-risk urban areas of
the U.S. This urban hazard mapping effort has been expanded in 2003 to
include the Tri-state Evansville area of Indiana, Kentucky, and
Illinois, as well as the St. Louis urban area of Missouri and Illinois.
In these new areas the USGS is serving more as a catalyst and
partner with local working groups.

In the Evansville area, the project is being lead by representatives
from the State Geologic Surveys of Kentucky, Illinois, and Indiana, the Southwest Indiana Disaster Resistant
Community Corp., the Central
U.S. Earthquake Consortium (CUSEC) emergency managers, CUSEC State Geologists, and the USGS.
