Development Of A Geographic Information System-Based Virtual Geotechnical Database And Assessment Of Liquefaction Potential For The St. Louis Metropolitan Area, Jae-Won Chung
Doctoral Dissertations
"The St. Louis Metropolitan area is the focus the U.S. Geological Survey's Earthquake Hazard Program's plan for assessing and reducing the likely risks of an earthquake likely emanating from New Madrid Seismic Zone (NMSZ), which is the most active seismic zone in the Midwestern United States. The St. Louis Metropolitan area consists of three counties in Missouri and four in Illinois, which are divided by the state boundary along the Mississippi River. Both of the state's respective geological surveys have produced their own geologic maps and datasets, employing dissimilar geodata information and systems, with differing map units, map scales, and …
Pilot Program To Assess Seismic Hazards Of The Granite City, Monks Mound, And Columbia Bottom Quadrangles, St. Louis Metropolitan Area, Missouri And Illinois, Deniz Karadeniz
Doctoral Dissertations
"Three 1:24000 scale quadrangles were selected for a pilot program intended to evaluate seismic site response across the spectrum of geologic conditions underlying the St. Louis Metropolitan area, using the Granite City, Monks Mound and Columbia Bottom quadrangles. These evaluations included assessments of: i) site amplification distributions; ii) probabilistic hazard analysis of PGA, 0.2 second and 1.0 second spectral accelerations for 2%, 5% and 10% probability of exceedance in 50 years; iii) two scenario earthquakes and their associated PGA, 0.2 sec, and 1 sec spectral accelerations; and v) sensitivity and uncertainty analyses. These hazard maps were prepared using a fully-probabilistic …
