Abstract : Work in four areas is reported. The first deals with the design and implementation small scale chemical explosions for the purposes of constraining the physical characteristics of the equivalent elastic source. The second major area of work is the experimental quantification of the effect of source depth in generating body and surface waves in the near-field. The third contribution reports attempts to determine the effect of scattering on near-field waveforms. A geological site characterization procedure is proposed. Finally, superposition experiments for two identical explosive sources are described. Keywords: Seismology; Scattering; Moment sensors.
