The New Madrid Seismic Zone (NMSZ) lies within the interior of the North American plate and is approximately 2000 km from the nearest active plate boundary. Yet, it has produced sequences of large earthquakes with widespread and coincident areas of paleoliquefaction features: A.D. 900±100, A.D. 1450±150, and 1811, 1812 (Tuttle et al., 2002). Several theoretical driving mechanisms of NMSZ intraplate earthquakes have been proposed (e.g., Grana and Richardson, 1996; Liu and Zoback, 1997; Kenner and Segall, 2000; Grollimund and Zoback, 2001; Pollitz et...
