The Wichita Mountains Seismological Observatory was engineered and is now being operated under the technical supervision of the Air Force Technical Applications Center (AFTAC) by The Geotechnical Corporation of Garland, Texas. The work is being performed as a part of Project VELA Uniform, under the overall direction of the Advanced Research Projects Agency (ARPA). The seismological equipment used is identical to that recommended in 1958 by the Conference of Experts for detecting violations of a possible agreement on the suspension of nuclear tests. The equipment recommended is quoted in Appendix I attached to this report. This is the first station to be built employing the recommended instrumentation and the capabilities of a control system using such instrumentation have not been determined. The observatory's performance should be of great interest to delegates of the United States, United Kingdom, and U.S.S.R. who are currently negotiating in Geneva for a ban on nuclear testing.
