Mid-Continent Geographic Science CenterPromises and challenges of data collected to aid the St. Louis Area Earthquake Hazards Mapping ProjectThe St. Louis Area Earthquake Hazards Mapping Project is a study of the U.S. Geological Survey. The study includes collection of geotechnical data from other sources to assist with subsurface characterization in the project area, which encompasses approximately 1,711 square miles (4,432 square kilometers) of Missouri and Illinois (fig. 1) within the St. Louis Metro area. Data sources include the U.S. Army Corps of Engineers, the Missouri Department of Transportation, and engineering firms. Interpretation of these data will aid the prediction of site response at various localities throughout the project area and the production of seismic hazards maps based on scenario earthquakes affecting the region.

Lead and zinc mining operations along the Viburnum Trend Subdistrict began in the Black River Basin in 1966. Arsenic, cadmium, cobalt, copper, lead, nickel, and zinc are the major trace elements associated with the sulfide minerals of this Mississippi Valley Type ore deposit. Clearwater Lake may be a sink where these mining-related trace elements accumulate and are stored. Sediment cores were collected from six sites in Clearwater Lake to spatially and temporally characterize the concentration of trace elements in the bed sediment. The Clearwater Dam site core is the only core that is known, with certainty, to have penetrated to the pre-impoundment (pre-1948) surface. The core from Logan Creek probably penetrated the pre-mining (pre-1966) surface; the lower Black River core penetrated the pre-mining surface based on lead-210 isotopic analysis. More information... Mid-Continent Geographic Science Center Mission Statement The mission of the Mid-Continent Geographic Science Center (MCGSC) is to conduct geographic research for the prediction, assessment, and mitigation of natural and manmade hazards, to monitor land use change, and to relate land cover dynamics to population, disease, and ecosystem change so policy makers at all levels of government can make informed decisions regarding current and future issues affecting their geographic regions. Rolla, MissouriThe Mid-Continent Geographic Science Center is located in Rolla, Missouri. Rolla, the county seat of Phelps County, is an attractive mixture of rural and urban life. It is the home of several high-technology businesses and Federal agencies, including the U.S. Geological Survey and the U.S. Forest Service. The University of Missouri at Rolla, which is a nationally recognized leader in science and technology, has educated students in Rolla for more than 125 years.Rolla is located at the crossroads of I-44, US 63 and Missouri Highway 72. Jefferson City, the state capital, is 62 miles to the north, St. Louis lies 106 miles northeast and Springfield is 110 miles southwest. |
