OSTI ID:4748419

Long range seismic measurements for the analysis of an underground nuclear test, STOAT, are presented. As a measure of the effectiveness of a network of hypothetical control stations having --1000 km spacing, a comparison is made between the actual location of the shot and its computed hypocenter as determined by a digital computer. Best-fit values of latitude, longitude, depth of focus, and time of origin are determined statistically by a least squares method. Short-period signals from the STOAT evert were recorded on film by 22 stations. Included are the P/sub n/ and P arrival times, the maximum amplitudes, and the travel time residuals from the P/sub n/ and P phase. Useful signals from STOAT were recorded to a distance of 1313 km. Following STOAT by approximates 27 minutes, a collapse event was recorded with measurable signals at 16 stations to a distance of 1005 km. (H.G.G.)
