Discrimination between underground nuclear explosions and shallow earthquakes using the vertical component of the Rayleigh wave is achieved using several techniques. This analysis includes the previous developed area under the Rayleigh wave ARZ, the newly applied total energy ERZ and the total energy transported across a unit width of the waveguide by the Rayleigh wave REF. Results for several explosions and earthquakes of varying magnitudes are presented. Evaluation of these techniques and their applicability in an automated discrimination program is discussed. An attempt is made to incorporate a matched filter approach for weak signals.
