By: , and 



A 50‐km aperture geodetic network centered on the proposed high‐level radioactive waste disposal site at Yucca Mountain, Nevada, was surveyed with GPS in 1993 and 1998. The average deformation rate across the area is described by the principal strain rates 22.8±8.8 nstrain yr N77.6°W±13.5° and −8.8±11.9 nstrain yr N12.5°E±13.5° (extension reckoned positive) and a clockwise rotation rate about a vertical axis of 9.6±7.4 nrad yr relative to fixed North America. Quoted uncertainties are standard deviations. Those strain rates are consistent with the geodetic strain rates (2±12 nstrain yr N87°±12°W and −22±12 nstrain yr N03°±12°E) previously reported by . [1999] for the 1983–1998 interval and with the low extension rate (5–20 nstrain yr) [., 1998] inferred from the geologic record. None of those strain rates is consistent with the 50±9 nstrain yr N65°W extension rate for the area reported by Wernicke et al.
