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 attenuation (in other words, seismic waves have the potential to do damage and propagate over a greater geographic area in this region than for the same magnitude earthquake in the western U.S.) necessitates being prepared for earthquake hazards. This dataset provides maps of probabilistic and deterministic earthquake ground motions and liquefaction hazard for the Evansville, Indiana metropolitan area. The following tables are available (see DATA_README.txt for additional information): Liquefaction potential measurements: lpi-cpt_evansville_pu-jhaase_2010-07-22.csv Liquefaction potential grid: lpi-grid_evansville_pu-jhaase_2010-07-22.csv Earthquake scenario ground motions for a New Madrid event: scenario-nm7-7_evansville_pu-jhaase_2010-06-06.csv Earthquake scenario ground motions for a Wabash Valley event: scenario-wv6-8_evansville_pu-jhaase_2010-06-06.csv Probabilistic earthquake ground motions: psha_evans_pu-jhaase_2010-06-06.csv
