Omega 3 Rock Motion Results

摘要

On July 29, 2000, a 100-metric ton high-explosive test, denoted Omega 3, was conducted inKazakhstan at the Degelen Mountain Test Site. The test was conducted by the Defense ThreatReduction Agency with the fielding support of the National Nuclear Center of the Republic ofKazakhstan. The explosive was granuatol (a common form of flaked TNT used for mining inKazakhstan). These tests were recorded by regional and some teleseismic stations. The purpose ofthese ground motion measurements was to provide new benchmark data on the seismic source regionin hard rock that had been previously damaged by an earlier high-explosive test, conducted onSeptember 25, 1999 (Omega 2). These tests were done in support of the Comprehensive Test BanTreaty Verification program. The measurements were made using two velocity measuring techniques.The gages were placed at ranges that varied from 13.5 m to 75 m from the center of the charge. Allthe gages registered data, albeit the accelerometers sometimes only gave time of arrival.
