Spectral modulation is used as a criterion for discriminating multiple mining explosions from earthquakes and single blasts. Features in the spectra of regional arrivals from quarry blasts may be explained by the spatio-temporal configuration of shot

A simple approach for the estimation of onset times of regional arrivals was tested. The method consists of the computation of the cumulative sum (CUSUM) of a test statistic, in this case, the absolute value of the trace amplitude, addition of a line

On September 10, 1996, The United Nations General Assembly adopted the Copmprehensive Nuclear-Test-Ban Treaty (CTBT), prohibiting nuclear explosions worldwide, in all environments. The treaty calls for a global verification system, including a networ

Seismic events located in the Gulf of Bothnia, the Baltic Sea, and the North Sea, recorded at the regional seismic arrays NORESS and FINESA, have characteristics of underwater blasts observed hydroacoustically. Spectral analysis of regional phases as

SUMMARY The particle motion of regional arrivals is frequently treated in automatic phaserecognition schemes as that appropriate to simple P or S waves incident on an elastic, laterally homogeneous half-space. This model implies that the motion in

Waveform modeling in the time domain matches the various frequency components of seismic signals unevenly; the agreement is better at low frequencies and becomes progressively worse towards higher frequencies. The net effect of this kind of time-doma

Regional arrivals, similarly to short-period teleseismic P waves, have a spectral structure that the Fourier transforms of individual sensors at arrays for events located in limited source regions can be decomposed into source and site spectral facto

The research under this program has investigated problems associated with transporting regional-phase amplitude ratios, such as Pn/Sn or Pn/Lg ratios. The first study investigated the effect of sensor site effects on the variance of P/S ratios. Using
