Summary

About 280 kilometers of multichannel (common-depth-point) seismic reflection profiles were obtained in the central Mississippi River Valley by Geophysical Service Inc. and Western Geophysical Company under contracts with the U.S. Geological Survey. The specific area of the profiles is southeastern Missouri, northeastern Arkansas, and northwestern Tennessee. Geologically, the area is located in the northern part of the Mississippi Embayment.

Purpose

Three large earthquakes with magnitudes (mb) in the range 7 to 7.5 occurred in the area in the Winter of 1811-12, damaging the town of New Madrid, Missouri, and profoundly affecting the land surface over a large area. Seismicity has continued at a relatively high level compared with elsewhere in the central and eastern U.S. The profiling was done to improve knowledge of regional geologic structure and to investigate tectonic features associated with the seismicity.
