EXECUTIVE SUIVEVIARY <br /> A probabilistic seismic hazard analysis of the Tenmile dam at the Climax mine, in north- <br /> central Colorado, has been performed. Seismic sources considered in the analysis included <br /> nine faults such as the Mosquito fault near the Tenmile dam and a background areal source <br /> (Colorado Rocky Mountains seismic source zone). Empirical peak acceleration attenuation <br /> relationships for stiff soil sites were used in the analysis. For typical return periods of 500 <br /> and 1,000 years, the probabilistic peak accelerations were 0.09 g and 0.14 g, respectively, <br /> for Tenmile dam. <br /> H:\CONTRACT\TENM1LE\iv iv M0412951500 <br />
