SEISMICITY, MECHANICS OF FAULTING AND CRUSTAL STRUCTURE WITHIN THE BASIN AND RANGE AND ADJOINING PROVINCES

Abstract

The University of Nevada's 3 component quartz-rod strainmeter installation at Round Mountain, Nevada has recorded a number of underground nuclear explosions at the Nevada Test Site, beginning with the megation-sized JORUM event September 16, 1969. That explosion, and the larger HANDLEY event on March 26, 1970 both produced static strain offsets of a few parts in 10 to the 9th power at Round Mountain. These offsets did not decay within the first few hours after the explosions. In both cases the strain offsets were in the sense of ground extension radial to the shot point, which is inconsistent with the assumption of a pure compressive source of strain.
