Although it is generally accepted that tectonic activity in the Basin and Range province (BRP) is highest along the region's eastern and western margins, significant Holocene and latest Pleistocene activity has occurred in the central BRP as well, including northern and eastern Nevada. Some such faults are depicted in the few existing active fault compilations, but detailed studies are generally lacking and the actual levels of activity are often misrepresented. Examples of Holocene or latest Pleistocene faulting in northern and eastern Nevada include the Black Rock, Tuscarora, Thousand Springs Valley, and Railroad Valley fault zones. The Black Rock ault zone has hosted two or more Holocene events, including an event within the past 1.1 ka and resulting in a prominent fault scarp about 2.2 m high crossing the playa floor of the Black Rock Desert. The Tuscarora fault zone cuts an alluvial/pediment surface in southwestern Independence Valley, north-central Nevada, forming a complex graben at least 15 km long and 3.5 km wide, and has probable late Holocene activity. Single- and multiple-event scarps along the Thousand Springs Valley fault zone in northeastern Nevada suggest a 2 m Holocene/latest Pleistocene event and a minimum 17 m displacement of an early- to mid-Quaternary surface. Fault scarp profiles from the Railroad Valley fault zone in east-central Nevada, which has an overall length of about 120 km suggest an early Holocene or latest Pleistocene event, single event displacements of 1.5 to 2.5 m, and a late Quaternary slip rate of 0.1 to 0.2 mm/yr.
