Engineering Seismology
Prepared by the Case Histories Committee for the Engineering Geology Division of the Geological Society of America, these histories are intended as reference material for the practicing geologist and for the college student. This volume, the eighth in the Case History series, presents the seismological aspects of the works of man—the civil engineer or engineering geologist interacting with the environment. Topics are in two categories—changes at a point (nuclear or chemical explosions and well injection or withdrawal) and changes on a line (damming a river or construction along a coastline).
Quasi-Permanent Deformation in the Elastic Zone Near Explosions

Abstract
The low frequency (<10 cycles per second) content of body waves from chemical explosions has been studied. The traces recorded on an FM magnetic tape recording system have been reduced for instrumental effects. The corrected data have a coherent but peculiar distribution. The shape of the distribution suggests an hypothesis about the nature and behavior of the medium. Not all facts are consistent with the proposed hypothesis. This may be due to low level of the energy spectrum considered and the nature of the FM recording system used. Digital recording, permitting greater accuracy, is suggested.
