Abstract:

The study examines the accidental interference of a teleseism from an earthquake with the seismic signals from an underground nuclear explosion by presenting a compilation of seismograms from thirty-two near-regional stations associated with the explosion. The explosion was detonated by the U.S. on 14 August 1969 at the Nevada Test Site. It had a yield of 3 kt seismic estimate and a depth of burial of 784 feet in alluvium. The interfering earthquake was a principal aftershock of a Kurile Island earthquake sequence, with a magnitude of 6.2 and a distance of 70 degrees from explosion. The explosion waveform was embedded completely in the teleseismic P-wave at all near-regional stations.
