Applied Research Associates, Inc. (ARA) acquired Weston Geophysical Corporation, a preeminent nuclear test monitoring firm, on Feb. 28, 2019. The press release is available here: https://www.ara.com/news/ara-acquires-weston-geophysical-corp

For the past 20 years, Weston has conducted seismic and geophysical research for government and commercial clients, and has worked with ARA for nearly seven years on a nuclear forensics project managed by the Defense Threat Reduction Agency (DTRA). Weston, which consists of nine seismologists/geophysicists, has expertise in seismic analysis and has performed work for DTRA, the Air Force Research Laboratory (AFRL), the U.S. State Department, and other Government and commercial customers.

In addition to theoretical and computational capabilities related to seismic wave propagation, Weston has developed a specialized capability to conduct active explosive field experiments to address specific nuclear and conventional explosion monitoring problems relating to event discrimination, source mechanics, yield estimation, seismic wave propagation and the diffusion of effluents in the near-surface from explosive events into the atmosphere.

Specific skills that Weston has expertise in:
- Advanced signal processing algorithms for highly accurate seismic event detection, location and characterization
- Field deployments to examine source phenomenology and monitor induced/triggered seismicity
- Coda-based studies of magnitude and other source parameters
- Regional surface-wave magnitudes and discriminants
- Three-dimensional seismic velocity models of the crust and upper mantle

We are sellers of Güralp Systems broadband seismometers and data acquisition equipment in the United States. For sales inquiries, please email: guralp_sales@westongeo.com
