Abstract:

Partial contents Nuclear test verification The curious case of the missing explosion Analysis of teleseismic P wave coda using multichannel deconvolution methods and comparison to finite difference calculations Salt dome-related seismicity near Kulyab, Tadjikistan, USSR Focal depths of shallow local earthquakes from comparison of polarization filtered data with synthetics Observations of first order mantle reverberations Yield estimates from vertical-and transverse-component Lg spectra and polarization filtering to enhance regional phases Numerical investigation of topographic effects on 2-D explosive line sources Estimates of seismic coupling and nuclear explosion yields using seismic magnitude and moment data.
