Shallow sediments can respond non‐linearly to large dynamic strains and undergo a
subsequent healing phase as the material gradually recovers following the passing of …

The Dry Alluvium Geology (DAG) project was Phase II of the Source Physics Experiment and
consisted of a series of four chemical explosive tests conducted in the same source hole on …

Underground explosions are observed to produce fewer and smaller aftershocks than
similar size earthquakes. The seismic magnitude difference Δ mx between an explosion and …

As a chemical explosion is buried, the mechanism for acoustic wave generation transitions
from fully gas‐generated at the surface to completely spall‐induced at full containment …

Discrimination of underground explosions from naturally occurring earthquakes and other
anthropogenic sources is one of the fundamental challenges of nuclear explosion …

Understanding the surface topographic change that results from underground explosions is
important for global security. Current techniques to relate the surface change to …

Seismoacoustic wave generation for two consecutive surface chemical explosions of the
same yield (approximately 1 ton TNT-equivalent) was studied during the Large Surface …

Correlation detectors are now used routinely in seismology to detect occurrences of signals
bearing close resemblance to a reference waveform. They facilitate the detection of low …

For fans of Oppenheimer, a riveting investigation into the modern nuclear weapons
landscape. Nuclear weapons are, today, as important as they were during the Cold War, and …

Two balls were dropped approximately 150 m down an open borehole as part of an
investigation into the aftershocks from a 51 ton TNT-equivalent chemical explosion. The ball …
