We introduce a transportable technique to determine the yield and depth of burial (DOB)
from seismic source spectra of underground nuclear explosions. We demonstrate this …

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 …

Earthquakes have repeatedly been shown to produce inaudible acoustic signals (< 20 Hz),
otherwise known as infrasound. These signals can propagate hundreds to thousands of …

Abstract The Source Physics Experiment (SPE) Phase I consisted of a series of over‐buried,
horizontally colocated chemical explosions at the Nevada National Security Site. Seismic …

Explosion sources have been observed to generate significant shear‐wave energy despite
their isotropic nature. To investigate this phenomenon, we conduct an analysis of the …

ABSTRACT The Source Physics Experiment (SPE) aims at improving explosion monitoring
techniques by investigating source characteristics of chemical explosions in geologic …

Distributed Acoustic Sensing (DAS) can record acoustic wavefields at high sampling rates
and with dense spatial resolution difficult to achieve with seismometers. Using optical …

Distributed Acoustic Sensing (DAS) is a rapidly develo** technology that can record
acoustic wavefields at high sampling rates and with dense spatial spacing difficult to achieve …

In this brief report we document algorithmic choices and updates to our code related to the
earthquake relocation portion of our tomographic imaging algorithm. We show results of …

The six declared nuclear tests of the Democratic Peoples' Republic of Korea defy current
earthquake/explosion discrimination methods that rely on relative energy contained in body …
