Equipment to Support the Development of High Resolution Geophysical Site Characterization Procedures

Abstract

An important application of high resolution geophysical exploration is the interpretation of strong ground motions from chemical and nuclear explosions. High dynamic range data acquisition systems which are capable of acquiring multiple channels of data are necessary. Ground motion sensors, data analysis microsystem, and field enclosures were supported under this grant. Spanning ground motions from the low level exploration environment to the strong levels next to explosive sources was done with a collection of geophones, seismometers, and accelerometers. Four applications of the new system are given, in a range of experiments from quantification of near-source ground motions from a contained nuclear explosion to the characterization of a new AFOSR supported shear wave generator. Keywords: Seismic detection; Seismology; Compressional waves; Shear waves; Geophone; Accelerometer; Geophysical site characterization.
