N2 - Ground motions generated by induced seismicity is an important consideration and design factor for the development of enhanced geothermal systems (EGS) and operations. Typically, ground motions are estimated from empirically based ground motion prediction equations using a moment magnitude and a distance with factors to account for local site conditions and in some cases faulting style. Ground motions specific to a site, recorded or modelled, for the specific site conditions and fault geometries may better inform hazard and risk calculations. Here we demonstrate a deterministic calculation of ground motions from postulated moment magnitudes at the Utah FORGE site using source-to-site earthquake simulations using the finite-element method in the codes, FALCON and MASTODON, developed and maintained at the Idaho National Laboratory. Sample results are presented from these simulations and a plan for future work is discussed.
