Reducing Hazards in the Central and Eastern U.S.

Geological Hazards Research and products for loss reduction in the Central and Eastern U.S. is accomplished through partnerships among USGS and academic, government, and private partners. USGS staff are located in the Memphis, Tennessee, field office at the Center for Earthquake Research and Information (CERI), in Golden, Colorado, and in Menlo Park, California. The map to the right shows earthquakes (circles) of the New Madrid and Wabash Valley seismic zones (orange patches). Red circles indicate earthquakes that occurred from 1974 to 2002 with magnitudes larger than 2.5 located using modern instruments (University of Memphis). Green circles denote earthquakes that occurred prior to 1974 (USGS Professional Paper 1527). Larger earthquakes are represented by larger circles. more info : Geological Hazards, reducing hazards Geological Hazards, instability Geological Hazards
