Abstract:

In the context of nuclear explosion seismology, surface wave magnitudes, MS, derived from measurements of Love or Rayleigh waves, have assumed particular importance since they are utilized in two areas, namely Discrimination - where the discrimination between explosions and earthquakes relies heavily on the contrast in surface wave generation by the two event types. This contrast is normally measured by MS vs body wave magnitude, mb, criteria. Determination of explosion yield using MS. In this paper, the background of surface wave magnitude determination is outlined, followed by discussions of present practice in surface wave measurements at both teleseismic and regional distances. A final section outlines recommended studies related to improving determination of surface wave magnitudes and other, more sophisticated, methods of evaluating long period energy content in the seismic surface wave train.
