The geology and tectonic setting of the New Madrid region in southeastern Missouri has received considerable attention because of the area's high seismic activity. The largest recorded earthquakes in this area occurred in the winter of 1811-1812. These earthquakes has estimated magnitudes as large as 8.0 on the Richter scale (Johnsonton and Kanter, 1990) and affected an area of about 1...

Photogeologic map showing distribution of sinkholes south of Fairplay, Park County, Colorado — A possible geologic hazard Photogeologic map showing distribution of sinkholes south of Fairplay, Park County, Colorado — A possible geologic hazard

A large group of at least 50, and perhaps significantly more, sinkholes partially surrounds Black Mountain 6-10 mi south Fairplay in South Park, Park County, Colorado. The sinkholes occur in bedrock in the evaporite facies of the Middle Pennsylvania Minturn Formation, and in Quaternary soil, alluvium, and glacial outwash gravels that overlie the evaporite beds. Sinkholes range in size...
