The basic results from the U.S. Department of Energy's (DOE's) Non-
Proliferation Experiment (NPE) for seismic signal generation are that the
source function for a chemical explosion is equivalent to that of a nuclear
explosion of about twice the yield and that the seismic moment measurements
are consistent between freefield, local, and regional measurements. In addition,
evidence was found that Pn in the Basin and Range province of the western
United States is a turning ray and is simply proportional to the source function
while the transfer functions for Pg and Lg are low-pass in nature.
The NPE was a comprehensive end-to-end experiment involving two
chemical explosions with measurements taken at all stages. The first explosion
was 300 lb of a very efficient military compound called C4. The second was
2,846,000 lb of an ammonium nitrate and fuel oil (ANFO) mixture, a relatively
inefficient explosive requiring more than a kiloton of it to produce an explosion
with an energy release of 1 kiloton. The small explosion was detonated first,
after which the emplacement chamber for the large one was excavated so
that the center of the large shot was co-located with that of the small one
(Figure 1). Seismic recordings of the small explosion provided empirical
Green's functions for later use in analyzing the kiloton explosion. Measurements
were made of the second explosion in the free field, on the mesa surface, and
locally off the mesa.
The NPE comprised extensive measurements of the all associated
phenomenology by many different groups. For explosion phenomenology
research, measurements were made of (1) the hydrodynamic motion within the
explosive, (2) the particle velocity and acceleration within and outside of the
