Abstract : Work in the past reporting period has been focused in four areas all related to our task of shallow geological site characterization using seismic waves. The first area of emphasis is documented in, Comparison of Sources for Shallow Seismic Imaging: Radiation, Energy and Bandwidth by Hayward and Pearson. This paper contrasts a variety of shallow seismic sources for P and S waves. The second paper, Characterization of the Shallow Weathered Zone with Complete Seismograms is by Bogaards and Stump. This work documents the separation of stochastic and deterministic wave propagation effects in the shallow weathered zone. The status of a parallel investigation designed to use the surface wave arrivals in constraining near-surface Q's and velocities is discussed in the third contribution by Mike Craven. Finally, the comparison of site characterization information is made to waveform variability observed from high explosive testing in Experimental Studies of Stochastic Geologic Influences on Near-Source Ground Motions by Reinke and Stump.
