Abstract : Seismic noise is the ambient ground motion within which signals of interest are to be detected. Because the distinction between seismic noise and seismic signature is application dependent, the ground motion representations presented in this report serve both as characterization of seismic noise that, for example, might interfere with the detection of walking people at the sites studied, and also as seismic signatures of the cultural activity at the three sites. The sites are: a wind farm on a remote moor in Scotland, an approx. 13 acre field bounded by woods in a rural Enfield, NH neighborhood, and a site transitional from developed to farmland within 1 km of the 6-lane M6 motorway near Keele, England. This report documents the variability in seismic noise at the three sites with site activity (wind farm), time of day (Enfield) and both time of day and day of the week (highway).
