<p><span>We have derived a new three-dimensional model of the lithologic structure beneath the city of </span>Memphis<span>, </span>Tennessee<span>, and examined its correlation with measured </span>shear<span>-</span>wave<span> </span>velocity<span> profiles. The correlation is sufficiently high that the better-constrained lithologic model may be used as a proxy for </span>shear<span>-</span>wave<span> velocities, which are required to calculate site-amplification for new seismic hazard maps for </span>Memphis<span>. The lithologic model and its uncertainties are derived from over 1200 newly compiled well and boring logs, some sampling to 500 m depth, and a moving-least-squares algorithm. Seventy-six new </span>shear<span>-</span>wave<span> </span>velocity<span> profiles have been measured and used for this study, most sampling to 30 m depth or less. All log and </span>velocity<span> observations are publicly available via new web sites.</span></p>
