Abstract : The simulation and prediction capability discussed is presently being used in the design of military seismic sensors. Specifically, the modeling techniques can be used to: Provide engineering data for the design or modification of seismic sensor components; Separate the various seismic generation mechanisms for further detailed study; Estimate performance of new seismic sensor devices in restricted areas throughout the world; Produce data for the design of sensor fields; Produce data for sensor maps which can be interpreted from other site characteristics. The accuracy of the model is only as good as the accuracy of the input data fed to it. Thus, for situations where site data are poor, measured and predicted results can vary significantly. However, ranges of values can be examined by using site data at maximum and minimum levels, which, in turn, will provide the military planner with significant background information.
