The Mississippi Embayment regional seismic hazard (Fuller, 1912; Nuttli, 1973, 1982, 1983), associated with the New Madrid seismic zone (NMSZ) is attributed to displacement on seismogenic structures primarily within the failed Reelfoot rift (Burke and Dewey, 1973; Ervin and McGinnis, 1975; Hildenbrand, 1977; Johnston and Shedlock, 1992).
