Abstract:

A 21-element portable seismic array system developed to measure the spatial and temporal characteristics of seismic waves is characterized by ruggedness, flexibility of aperture and channel response, transportability, minimal manpower requirements, operational simplicity, unattended operation, and ability to withstand climatic extremes. The system performance relates to the local environment by delineating signal and noise coherency loss. These qualities are advantageous for monitoring earth motions affecting the performance of motion-sensitive instrumentation, for relating the seismic wave field to geology in teleseismic detection problems, for discriminating between manufactured sources in areas of seismic surveillance, and for subsurface crustal mapping of hardened site areas.
