Abstract: Ground effects resulting from certain HARDTACK II underground
explosions were measured by strong-motion and teleseismic seismographs
from 2000 ft to distances of nearly 100 miles. In addition, many
temporary seismographs were operated by a number of organizations to
distances of nearly 2400 miles, and routine seismographs continued to
operate on a worldwide basis. Some of the results are given in this
report. For safety purposes, predictions of ground effects, using
formulas derived by the Coast and Geodetic Survey from pre-Rainier H.
E. tests and modified slightly as a result of the Rainier tests, hold
with reasonable accuracy. However, it is believed that low frequency
ground displacements in the distance ranges covered in this report
attenuate, with absorption, as the first power of the distance. An
energetic wave believed reflected from the surface near the source was
recorded by some of the strong-motion seismographs. It is out of phase
with the initial wave and follows it by about a quarter second. From
the ground effects standpoint, the Blanca shot was equivalent to a
magnitude 4.8 earthquake. ;
