Abstract
This is one in a series of five seismotectonic maps of the seismically active New Madrid area in southeast Missouri and adjacent parts of Arkansas, Kentucky, and Tennessee (table 1). ). We cannot legibly show all the seismotectonic data on a single map, therefore each of the five maps in this series groups a different type of related information. Rhea and others (1994) summarized the background and purpose of the seismotectonic map folio. To aid in locating small features mentioned in the text and tables we have divided the map area into 16 tracts (fig. 1); some of the small features are identified by tract number.
The focus of this map is earthquake effects in the New Madrid area. The first part of the discussion is a description of some superficial effects of three great earthquakes that struck the map area during the winter of 1811-12 (Nuttli, 1973). Next, we discuss other possible records of recent deformation that may have bearing on the assessment of seismic hazards. Finally, some features of uncertain origins are discussed; these have unknown bearing on hazard assessment. Some swampy or flooded areas, locally called sunklands, are discussed in two places because two of the sunklands formed or enlarged during the 1811-12 earthquakes, whereas the others are of uncertain origins.
