The first cycle of seismic waves recorded at distances of 45,
300 and 355 km. from the GNOME nuclear explosion was used to determine
whether the near source wave characteristics at 0.3 km.
could be determined from distance measurements. Both head wave
and body wave propagation were considered. First the recorded signals
at distance were inversely propagated back to the near source
region as head waves, and secondly, the measured source at 0.3 km.
was propagated out to 300 km. from the source as a body wave. In
both cases, restricted comparisons between theory and observation
can be made, but the comparison appears to favor the body wave type
of propagation. More research is needed to make a more conclusive
choice between the two modes of propagation. Methods were developed
which can be used to determine source motion from distance measurements
when the data are sufficient to do so. / Graduation date: 1965
