ABSTRACT

Seismic Hazard Assessment at the Fallon, Nevada, Frontier Observatory for Research in Geothermal Energy Site   [open pdf - 7MB]

From the Document: "Given the potential for inducing seismicity and the associated shaking hazard, stimulation scenarios require careful consideration including site characterization and assessment throughout various stages of a project to minimize the seismic hazard of such stimulation. To address the seismic hazard specifically, a probabilistic seismic hazard assessment (PSHA) is often required and is generally part of an induced seismicity mitigation plan (ISMP). [...] A specific PSHA for the proposed Fallon, Nev., FORGE [Frontier Observatory for Research in Geothermal Energy] site is outlined below that relies solely on hypothetical stimulation scenarios and analog sites to assess the hazard of induced seismicity in the absence of local microseismicity. We begin by reviewing the tectonic setting and natural seismicity in the region and then expand on the methods used in probabilistic seismic hazard analyses. This is followed by a discussion of the results and evaluation of ground shaking at significant sites in the vicinity of the Fallon FORGE site."
