Non-Destructive Testing for Earthquake Hazards Mapping, Southeast Missouri, USA

Abstract

Multi-Channel Analysis of Surface Waves (MASW), Seismic Cone Penetrometer Test, Cross-hole and Ultrasonic Pulse Velocity shear wave velocity (Vs) data were acquired at 40 sites in the Poplar Bluff study area, southeast Missouri, USA. Poplar Bluff is located near the New Madrid Seismic Zone of southeast Missouri and adjacent states, the scene of three magnitude 7.5 to 8.0 earthquakes in 1811-1812. The Poplar Bluff area includes terrain in two very different physiographic provinces, the alluvial soil lowlands of the Mississippi Embayment and the residual soil uplands of the Ozarks. Shear wave velocity data along with databases of soil stratigraphy were used to characterize the geomaterials and generate a suite of 3-D maps depicting spatial variations in thickness, stratigraphy and Vs of soils in the Poplar Bluff area. A 3-D shallow subsurface materials model, complete with Vs test data, and an earthquake soil amplification map were prepared as well. These maps depict the lateral variability of the shallow subsurface geomaterials' Vs and stratigraphy,' and their range of values or properties. The MASW technique for determining Vs was found to be the most useful and economical.
