DOE Non-Proliferation Experiment includes seismic data



The U.S. Department of Energy detonated approximately 1.29 million kg of a commercial blasting agent, based on ammonium nitrate and fuel oil (ANFO), at the Nevada Test Site (NTS) on September 22, 1993, at 00:01.080 a.m. Pacific Daylight Time. The blasting agent was emplaced in a cylindrical chamber, approximately 15.2 m in diameter × 5.5 m high, located at 37.20193°N and 116.20986°E in a Rainier Mesa tunnel, 390 m underground. Code-named the Non-Proliferation Experiment (NPE), the explosion had an energy release of approximately 1 kt (1 kiloton = 4.186×1012 joules).
