Abstract:

Infrasonic monitoring is a relatively low cost and robust means of monitoring for atmospheric explosions, which was used from the early 195Os through the mid 1970s by the US for monitoring purposes. Source yields anticipated under a Comprehensive Test Ban Treaty monitoring regime are lower than they were during the years of atmospheric testing, with the result that the frequency range of interest is moved to higher values. We present a brief review of infrasound physics and propagation and review the results of recent DOE supported research at Los Alamos National Laboratory. Recent data from large surface explosions is discussed with regard to current monitoring interest. Considerations of synergy among infrasound and other monitoring technologies are presented. Results from earlier work are in good agreement with more recent measurements for kiloton sized explosions. Infrasound continues to be an excellent technology for inclusion in the International Monitoring System for a Comprehensive Test Ban Treaty.
