Preliminary Report on Long Range Seismic Measurements Participation in Project Miracle Play-Diode Tube.

摘要

The MIRACLE PLAY - DIODE TUBE gas explosion in a cavity in Tatum Dome, Mississippi, was monitored by eight LRSM teams operating 3-component short-period and long-period seismographs. Four teams encircled the salt dome and occupied approximately the same sites as were occupied during the STERLING experiment. Four more teams encircled the Lucedale, Mississippi (LD-MS) site where an anomalous signal was recorded from the STERLING shot. High winds during the time of the arrival of the DIODE TUBE signal at LD-MS resulted in a record with a low signal-to-noise ratio. Spectrum analysis and coherence measurements indicate that the DIODE TUBE signal was recorded at LD-MS by the radial seismograph. The DIODE TUBE signal amplitude was about one-third the STERLING amplitude according to measurements of the largest waves in the STERLING and DIODE TUBE recordings of the radial seismographs. (Author)
