Data Release Report for Source Physics Experiment 4Prime (SPE-4Prime) Nevada National Security Site
- National Security Technologies, LLC. (NSTec), Mercury, NV (United States)
The fourth test in the Source Physics Experiment series (SPE-4Prime) was conducted at a granite site in Nevada on May 21, 2015, at 18:35:44.000,003,989 ± 20 nanoseconds Coordinated Universal Time. The explosive source was 69.1 kilograms (kg) (including detonator assembly) of Composition C4 plastic explosive (89.14 kg TNT equivalent) detonated at a depth of 87.2 meters (m). The explosion was recorded by an extensive set of instrumentation that includes sensors both at near-field (less than 100 m) and far-field (100 m or greater) distances. The near-field instruments consisted of three-component accelerometers installed at various depths from 7 to 99 m in boreholes positioned around the source hole, and a set of single-component vertical accelerometers on the surface. The far-field network was composed of a variety of seismic and acoustic sensors, including short-period geophones, broadband seismometers, and three-component accelerometers at distances of 100 m to 25 kilometers. Infrasound data were collected from ground-based sensor arrays at distances out to 5 kilometers.
