Response to Action Item GS-16 and Follow-up from FMEA Workshop: Induced Earthquakes at the Resolution Copper Mine and TSF

In response to GS-16, I have evaluated two potential issues that have been raised as part of the EIS process and risk assessment for the proposed Resolution Copper Mine and tailings storage facility (TSF).

Tectonic Stresses in Mine Seismicity: Are They Significant?

Lithostatic stresses and their redistribution around mine excavations are thought to be the dominant driving force in the generation of most mine tremors and rockbursts.

Site-Specific Seismic Hazard Evaluation for the Proposed Resolution Copper Mine, Southern Arizona

A probabilistic seismic hazard analysis (PSHA) and deterministic seismic hazard analysis (DSHA) were performed for Resolution Copper’s Mine site including the area above the deposit (Mine area) and the area covering the East Plant site (Shafts 9/10).

Contemporary Seismicity, Faulting, and the State of Stress in the Colorado Plateau

The contemporary seismicity of the Colorado Plateau based on seismic monitoring in the past 30 yr can be characterized as being of small to moderate magnitude, and contrary to earlier views, of a low to moderate rate of occurrence with earthquakes widely distributed.
