英文摘要	Analysis of a small earthquake swarm near Virginia City, NV, reveals complex structural features, including an interplay of both fluid-driven and aseismic-driven earthquake migration within a naturally occurring tectonic sequence. The Virginia City earthquake sequence occurred over ~10 days in January 2014. We relocate 305 events to reveal three separate, well-defined planar structures. The earthquakes initially migrate at a rate consistent with pore fluid diffusion, outlining a moderately dipping plane. The earthquakes then jump to a vertical plane and migrate at a higher rate; the sequence continues to migrate rapidly onto a third, shallowly dipping plane, consistent with rates observed elsewhere associated with aseismic creep. Focal mechanisms indicate right-lateral strike slip on the vertical plane and both normal and left-lateral strike slip movement on the other planes, and the newly imaged structures illuminate the orientation of active faults at depth in the Walker Lane tectonic region. © 2020.
