ABSTRACT
Carson City has the highest earthquake hazard in Nevada and, perhaps, in the entire Basin and Range Province. Several historical earthquakes have shaken the city, including one of the most damaging earthquakes in Nevada, the 1887 Carson City earthquake. Background earthquakes, magnitude 3 and smaller, are frequent. Areas of persistent background seismicity include the northern part of Carson City, south of Prison Hill, and the northern Pine Nut Mountains. Several young earthquake faults exist in and around Carson City. Larger faults bound the mountains and smaller faults are within the mountains and/or basins. There is evidence in the geologic record of local paleoearthquakes with magnitudes in the upper 6 to 7 range, some of which were ~200 years apart along a single fault. Probability calculations indicate it is likely (78–79%) Carson City will experience Modified Mercalli Intensity (MMI) VI shaking levels over a 50-year time period. The probability of damaging MMI VII shaking over a 50-year time period the probability is 55–57%. Carson City also faces potential surface ruptures, earthquake-induced liquefaction, and earthquake-induced landslides and rock falls.
