Long-Period Rayleigh Wave Spectra from Earthquakes and Explosions
Abstract
Comparisons are made of Rayleigh wave spectra for Nevada Test Site explosions and Nevada earthquakes and for a limited number of teleseismic explosions and earthquakes recorded in North America. For a given combination of source and receiver location, the explosions consistently exhibit the same spectral shape over a significant range of magnitudes while spectral shapes for earthquakes commonly vary in a manner that appears independent of magnitude, with some earthquake shapes closely matching those of explosions. The spectral shapes for explosions were commonly observed to vary significantly from station to station at comparable distance ranges, probably because of path and receiver site effects. Neither Rayleigh spectral shape nor symmetry of raw surface wave radiation patterns is likely to be a reliable discriminant in general.
