Memphis has a dense urban population near faults capable of producing major earthquakes.
A high probability of a moderate earthquake in the near future (e.g., a 25-40% probability of a magnitude 6.0 or greater in the next 50 years), and relatively low regional attenuation (in other words, seismic waves do damage over a greater area in this region than for the same magnitude earthquake in the west) lead to significant earthquake hazard in the Memphis metropolitan area. Memphis lies within the New Madrid seismic zone, which is the most seismically active and well-studied region in the Central and Eastern U.S.
These datasets include probabilistic and deterministic maps and data, as well as liquefaction potential maps, data, and documentation.
