During the week of 15 February 1982, S-CUBED participated in Phase II of the sequence of explosive tests in salt carried out by Physics Applications, Incorporated PAI. Our role in these tests was to monitor the seismic ground motions at distances from 1 to 16 kilometers and to determine the dependence of peak velocity, signal shape, and spectral components on range, azimuth, and explosion type. The tests consisted of two Nirtomethane explosions with yields 200 and 70 pounds and one Pellitol explosion at 200 pounds. These shots, along with a mining blast, were monitored along two azimuths 100 degrees apart at ranges from 1 to 16 kilometers. This report describes our data acquisition procedures and offers preliminary analyses of the data.
