...J. C. Savage; W. T. Kinoshita; W. H. Prescott abstract Repeated surveys of a trilateration network (aperture greater than 20 km) centered on ground zero for the HANDLEY event, a nuclear explosion at the Nevada Test Site with yield in excess of 1 megaton, suggest that the explosion induced an east...

... strain meter installation at Round Mountain, Nevada (38°42.1'N, 117°04.61W) has recorded a number of underground nuclear explosions at the Nevada Test Site, beginning with the mega- ton-sized JORUM event September 16 1969. Both that explosion and the larger HANDLEY event on March 26 1970 produced static...

.... A multipole source model is derived for the strain-step field associated with the nuclear blast HANDLEY set off at the Nevada Test Site on March 26, 1970. The results suggest that there was significant fault movement associated with the detonation. 19 6 1972 Copyright © 1973, by the Seismological...

PAPANEK ABSTRACT The underground nuclear explosions BENHAM, PURSE, JORUM, and HANDLEY, detonated on Pahute Mesa, initiated earthquake sequences lasting approximately 70, 10, 20, and 60 days, respectively. Earthquakes...

... EVENTS JORUM AND HANDLEY BY DONALD V. HELMBERGER AND DAVID M. HADLEY ABSTRACT Several strong-motion seismograms recorded at 8 km from a large nuclear test at Pahute Mesa, Nevada Test Site, are modeled using the Cagniard-de Hoop technique. The ratio of vertical to radial motions suggest that the peak...

... period) sand, which is largely productive in southeastern Ohio. The main net result of all these efforts has been failure, as the “Clinton” has not yet been reached, owing to regrettable accidents that have caused most of these tests to be abandoned. Drilling has, however, been carried to greater depths...

... provides a useful means for summarizing the data. Note that the amplitude of the curve fit to the GREELEY data is larger than that for HANDLEY, as well as being slightly rotated. The sine curve amplitude, a, is a measure of the sinusoidal variation about the mean. In order to provide a statistical test...
