Summary Amplitudes of Rayleigh waves generated by some southern Nevada nuclear explosions and cavity collapses were analysed. The Rayleigh amplitude radiation patterns of the explosions and collapses were found to be strongly affected by the Earth structure along the travel paths from source to receivers. The effect of any tectonic strain release on the Rayleigh wave amplitude radiation patterns is believed to be small for most of the explosions studied. The corrections to the amplitudes for the effect of the travel path to each recording station were determined. Use of these amplitude corrections can improve the estimate of surface wave magnitude for seismic events in the southern Nevada region.
