Long-Range Seismic Recording of the MISTY PICTURE High Explosive Test, White Sands Missile Range, New Mexico

摘要

The Solid Earth Geophysics Branch of the Air Force Geophysics Laboratory recorded the MISTY PICTURE high explosive test at nine sites in the Tularosa Basin of southern New Mexico. Each site consisted of a three component seismometer set and a digital event recorder. The stations were due south of the explosion between 95 and 127 km. Analysis of P-wave travel times indicates that the crust is 30-32 km thick beneath the Tularosa Basin, a side graben of the Rio Grande Rift. S-wave travel times are consistent with earlier surface wave results. Polarization analysis indicates complex scattered and converted energy between the P- and S-wave groups.
