“…A similar conclusion was also drawn by Cramer (2001) and Newman et al (2001). However, Frankel (2004) compared the hazards at the low annual probability of exceedance between San Francisco and the New Madrid using an assumed standard deviation (0.38) for the New Madrid seismic zone and drew his conclusion.…”

“…This approach possesses inherent uncertain- ties in input parameters (Cramer, 2001;Chapman et al, 2006;Cramer et al, 2006), such as (1) input time histories, (2) attenuation relations, and (3) reference V S soil profiles. Of these input parameters, the input time histories and the attenuation relations appear to be the most important parameters for site-response modeling (Newman et al, 2001;Destegul, 2004;Karadeniz, 2008). A detailed sensitivity analysis was beyond the scope of this article.…”

The New Madrid seismic zone lies beneath the upper Mississippi Embayment, straddling the border between southeastern Missouri and northwestern Tennessee. In late 1811 and early 1812, it produced five earthquakes of magnitudes > 6:5, violently shaking the central and eastern United States (CEUS). Its magnitude and recurrence are of concern to today's central United States regions. By considering the effects of local geology, deterministic scenario maps (M w 7.3 and 7.7) were produced for ground motions intended to simulate the 7 February 1812 event (NM3), which was the largest felt. These maps include spatial estimates of peak ground acceleration and of 0.2 s and 1.0 s spectral acceleration (SA). Compared with the isoseismic map of modified Mercalli intensities (MMIs) in southeast Missouri, the MMIs converted from 0.2 s SA suggest that M w 7.7 is a plausible scenario for NM3. To better constrain its magnitude, other CEUS sites shaken during NM3 were also examined. Local site conditions were studied and evaluated before calculating the threshold magnitude for the reported MMIs. These results indicate that the magnitude of NM3 was at least M w 7.6, which validates our estimated size of M w 7.7 for southeastern Missouri.

“…Although none is well-constrained and estimates vary, it is interesting to examine the effect of alternative choices. Two assumptions involve the size and effects of future large earthquakes (Newman et al 2001). The first is the magnitude assumed for the largest future earthquakes, sometimes termed the "characteristic" earthquakes, in the New Madrid and South Carolina areas.…”
