Reno Area Seismicity 1980-1994 Color shaded relief image the Reno-Carson City-Lake Tahoe region of the eastern Sierra Nevada. Circles are the locations of earthquakes from 1980-1994. The earthquake locations were determined and provided by Diane dePolo of the University of Nevada Seismological Laboratory. The largest symbol represents an event of M 4 (see M 4 event in the north Reno area) and the symbol size is proportional the the earthquake magnitude. The smallest events are M 1.0 and below. The image is in a UTM projection with coordinate grid spacing at 10 km intervals. Ken Smith ken@seismo.unr.edu
