Taylor, S R

The general characteristics of seismic noise are reviewed in terms of its source, mode of propagation, seasonal variations, and variation with depth. The characteristics of the noise spectrum as a function of depth are important for extrapolating surface noise surveys to the expected noise in a borehole. A literature review of measured noise spectra in the vicinity of the five proposed Regional Seismic Test Network sites is combined with direct noise measurements from the National Seismic Station at the Cumberland Plateau Observatory and the LRSM station at Red Lake, Ontario. Results from a recent noise survey in the Adirondacks and Black Hills are also reviewed. Minimum noise values at all five Regional Seismic Test Network sites are tabulated at 1 Hz and appear to be higher than those of the low noise model of Brune and Oliver (1959).
