Abstract
The 1811-1812 New Madrid earthquakes affected a large area in the Central United States. The seismic hazard is low since large-magnitude earthquakes such as these are infrequent. However, the seismic risk is considerable due to the geology and building codes that do not adequately reflect the seismic hazard. The strong ground motions observed during the 1811-1812 earthquakes are attributed to the soft deposits and the deep soil column encountered in the Mississippi Embayment. This study evaluated the effect of embayment deposits on dynamic site response. Remote sensing imagery was evaluated to identify soils susceptible to ground motion amplification. Regional and local shear wave velocity (Vs) profiles were developed to model conditions at soil sites based on the age of near-surface geologic deposits.
