Site-Specific Seismic Hazard Analyses for the Resolution Mining Company Tailings Storage Facilities Options, Southern Arizona
At the request of Resolution Mining Company (RMC), this report presents the results of sitespecific probabilistic seismic hazard analyses (PSHA) and deterministic seismic hazard analyses (DSHA) of four sites for the RMC tailings storage facilities options in southern Arizona. The four sites include two sites within the proposed Far West Tailings Management Area: Far West 1 (on alluvium) (33.216° N latitude and -111.296° W longitude) and Far West 2 (on hard rock) (33.217°N latitude and -111.234°W longitude); one site in the proposed Near West Tailings Management Area (33.313°N latitude and -111.195°W longitude); and one site in the proposed Pinto Valley Operations (PVO) Tailings Management Area (33.405°N latitude and -110.968°W longitude) (Figure 1). Far West sites 1 and 2 are located in northern Pinal County, 80 and 86 km southeast of Phoenix and 117 km and 115 km north of Tucson, respectively (Figures 1 and 2). The Near West site, 14 km northeast of Far West 1 and also in northern Pinal County, is located 85 km southeast of Phoenix and 125 km north of Tucson. The PVO site is located in southwestern Gila County, 23 km northeast of the Near West site, 104 km east of Phoenix and 132 km north of Tucson (Figures 1 and 2).
