Abstract:

The MINE DUST HE shot of May 10, 1972 was recorded at a number of seismograph stations operated by the University of Michigan, the U. S. Geological Survey, and by the NOAA Special Projects Group. The recordings obtained at the close-in University of Michigan stations disclosed that this shot was a factor of 1.30 larger than the previous HE shot of this series, based on particle velocity measurements. The geometric means of an energy ratio measure indicated that MINE DUST HE was 1.23 times larger than DIAMOND MINE HE that DIAMOND DUST was 5.67 times larger than MINE DUST HE that DIAMOND MINE was 6.32 times larger than DIAMOND DUST.
