Earthquakes

Photograph of the Quaternary fault at the base of the Argenta Rim, Lander County. Chet Wrucke, USGS geologist, stands at the fault surface. Striations on the fault plane are slickensides that indicate oblique slip along the fault, with both normal (hanging wall down, footwall up) and left-lateral strike slip displacement.

Backhoe trench along the Genoa fault near Walley's Hot Springs, south of the town of Genoa, Douglas County. The maximum displacement along the fault during its last event, about 550 to 650 years ago, was 5.5 meters. NBMG geologist John Bell points at the fault plane.
