Surficial geologic map of the Northwest Memphis quadrangle, Shelby County, Tennessee, and Crittenden County, Arkansas
The depiction of geology on this map is designed to aid in urban planning and analysis of potential damage in the event of strong earthquake motion. The geologic map by itself does not analyze potential earthquake damage, but is designed to be used by seismologists who perform such analyses. The nature of geologic materials to a degree determines the severity of damage to infrastructure sustained during a strong earthquake.
