Effects of Radiation Patterns on Spectra and Magnitude Estimates.
Abstract
According to surface-wave radiation pattern theory, amplitude at any given period is a function of azimuth for a given tectonic source at a given depth. Also the shape of the observed spectra is dependent upon azimuth as well as depth and source type. For a source with a constant magnitude force system, a uniform far-field measurement of its strength, namely Ms, can vary by up to one unit of magnitude depending on angles of dip and slip. Body-wave radiation pattern theory predicts that amplitude will be dependent on take-off angle as well as azimuth. (Author)
