Earthquake Loss Reduction in the Central and Eastern U.S.


To understand geologic controls on earthquakes in the central and eastern U.S.


After conducting geological mapping in the St. Louis and Evansville-Henderson (Kentucky) areas through collaboration with the states and universities in the region, this project will generate much-needed earthquake hazard maps. USGS geologists will assist geologists of the Kentucky, Indiana, and Illinois State Geological Surveys to map surficial geology at 1:24,000 scale, to compile existing subsurface data, to acquire new subsurface data by drilling and cone penetrometer testing, and to construct geologic cross sections. This work and these products will elucidate the thickness and nature of shaking- and liquefaction-prone sediments upon which infrastructure may be founded in and around the three cities.
