Evansville Area Earthquake Hazards Mapping Project Completed
On February 7th, 2012, the U.S. Geological Survey and local and regional partners unveiled a new series of seismic hazard maps that outline the effects from quakes occurring in the Evansville area.
These earthquake hazard maps are critical tools to business leaders, city planners, emergency management and homeowners since the Evansville area is at risk from both the New Madrid and the Wabash Valley seismic zones.
The Evansville Area Earthquake Hazards Mapping Project is being led by representatives from Purdue University, the Center for Earthquake Research and Information at the University of Memphis, the State Geologic Surveys of Kentucky, Illinois, and Indiana, the Southwest Indiana Disaster Resistant Community Corp., the Central U.S. Earthquake Consortium State Geologists, and the USGS.

Evansville Urban Seismic Hazard Maps, v2010
Evansville, Indiana has a dense urban population near faults capable of producing major earthquakes. A high probability of a moderate earthquake in the near future (e.g., a 25–40% probability of a magnitude 6.0 or greater in the next 50 years) from the New Madrid seismic zone, and more moderate probability of a similar-sized earthquake in the Wabash Valley, coupled with relatively low regional att - Maps
Surficial geologic map of the Evansville, Indiana, and Henderson, Kentucky, area
The geologic map of the Evansville, Indiana, and Henderson, Kentucky, area depicts and describes surficial deposits according to their origin and age. Unconsolidated alluvium and outwash fill the Ohio River bedrock valley and attain maximum thickness of 33-39 m under Diamond Island, Kentucky, and Griffith Slough, south of Newburgh, Indiana. The fill is chiefly unconsolidated, fine- to medium-grain - Publications

The Evansville (Indiana) Area Earthquake Hazards Mapping Project was completed in February 2012.

Evansville, Indiana, has experienced minor damage from earthquakes several times in the past 200 years. Because of this history and the fact that Evansville is close to the Wabash Valley and New Madrid seismic zones, there is concern about the hazards from earthquakes. Earthquakes currently cannot be predicted, but scientists can estimate how strongly the ground is likely to shake as a result of aAuthorsChris Cramer, Jennifer Haase, Oliver BoydUnderstanding earthquake hazards in urban areas - Evansville Area Earthquake Hazards Mapping Project
The region surrounding Evansville, Indiana, has experienced minor damage from earthquakes several times in the past 200 years. Because of this history and the proximity of Evansville to the Wabash Valley and New Madrid seismic zones, there is concern among nearby communities about hazards from earthquakes. Earthquakes currently cannot be predicted, but scientists can estimate how strongly the grouAuthorsOliver S. BoydProbabilistic seismic hazard assessment including site effects for Evansville, Indiana, and the surrounding region
We provide a probabilistic seismic hazard assessment for the Evansville, Indiana region incorporating information from new surficial geologic mapping efforts on the part of the U.S. Geological Survey (USGS) and the Kentucky and Indiana State Geological Surveys, as well as information on the thickness and properties of near surface soils and their associated uncertainties. The subsurface informatioAuthorsJennifer S. Haase, Tim Bowling, Robert L. Nowack, Yoon S. Choi, Chris H. Cramer, Oliver S. Boyd, Robert A. BauerEarthquake scenario ground motions for the urban area of Evansville, Indiana
The Wabash Valley seismic zone and the New Madrid seismic zone are the closest large earthquake source zones to Evansville, Indiana. The New Madrid earthquakes of 1811-1812, over 180 kilometers (km) from Evansville, produced ground motions with a Modified Mercalli Intensity of VII near Evansville, the highest intensity observed in Indiana. Liquefaction evidence has been documented less than 40 kmAuthorsJennifer S. Haase, Robert L. Nowack, Chris H. Cramer, Oliver S. Boyd, Robert A. BauerLiquefaction hazard for the region of Evansville, Indiana
We calculated liquefaction potential index for a grid of sites in the Evansville, Indiana area for two scenario earthquakes-a magnitude 7.7 in the New Madrid seismic zone and a M6.8 in the Wabash Valley seismic zone. For the latter event, peak ground accelerations range from 0.13 gravity to 0.81 gravity, sufficiently high to be of concern for liquefaction.

Maps of surficial geology, deterministic and probabilistic seismic hazard, and liquefaction potential index have been prepared by various members of the Evansville Area Earthquake Hazard Mapping Project for seven quadrangles in the Evansville, Indiana, and Henderson, Kentucky, metropolitan areas. The surficial geologic maps feature 23 types of surficial geologic deposits, artificial fill, and undiAuthorsOliver S. Boyd, Jennifer L. Haase, David W. MooreSpatial earthquake hazard assessment of Evansville, Indiana
The earthquake hazard has been evaluated for a 150-square-kilometer area around Evansville, Indiana. GIS-QUAKE, a system that combines liquefaction and ground motion analysis routines with site-specific geological, geotechnical, and seismological information, was used for the analysis. The hazard potential was determined by using 586 SPT borings, 27 CPT sounding, 39 shear-wave velocity profiles anAuthorsT.D. Rockaway, J.D. Frost, Donald L. Eggert, R. Luna
