Welcome to the DTRA Verification Database operated by SAIC on behalf of the U.S. Department of Defense .
This site provides access to a host of data resources and products supporting research and development in the area of nuclear explosion monitoring and treaty verification.
Resources are organized into four main categories
  Data Retrieval tools provide access to an extensive (>18 Terabytes) and rapidly accessible archive of hydroacoustic, infrasound and seismic waveforms, covering 1994-present, and access to an archive of event bulletins from the Prototype International Data Center (PIDC, 1995-September 2001) and the International Data Centre (IDC, 2000-2004).
  Infrasound Stations pages provide access to the data availability statistics and infrasound station metadata from stations that are part of the International Monitoring System (IMS) network and a few selected non-IMS sites.
  Research Databases are a collection of unique databases that provide access to waveforms, signal measurements and source information drawn from a wide variety of official and unofficial sources for nuclear explosions, "ground truth" locations and infrasound events.
  Library provides access to a digital repository of documents related to nuclear explosion monitoring research and development.
