Overview of Seismic Noise and it's Relevance to Personnel Detection

Abstract

Seismic noise refers to the ambient ground motion within which signals of interest are to be detected. Four categories of seismic noise identified by source-road (vehicle), train, wind, and ocean micro-seisms-are reviewed. Examples are given of the variation in seismic noise by geographic location and by season and time of day, and of a technique to characterize seismic site effects from local seismic noise. Noise impact on seismic detection of personnel is discussed, and ground motion induced by a walking person is compared with noise at a rural site when cultural activity is minimal and when a moving vehicle is present.
