“…Horizontal component instruments were deployed at selected stations in 1984. This network, called the southern Great Basin seismograph network (SGBSN) (Rogers et al, 1981(Rogers et al, , 1983Mermonte and Rogers, 1987;Gomberg, 1991aGomberg, , 1991bHarmsen and Bufe, 1992), was designed to locate and study properties of earthquakes for a region containing tectonic features of possible significance to seismic risk assessment for the YMR. Tectonic features of regional interest (not all of which are significant for seismic risk assessment for Yucca Mountain) were reviewed by .…”
