N2 - The 10 November 2012 Mw 4.2 Perry County earthquake may represent a continuation of the seismically active Eastern Tennessee seismic zone (ETSZ) farther north than previously recognized into southeastern Kentucky. The mainshock and aftershock data from regional seismic networks and EarthScope's Transportable Array stations allowed highquality determinations of the source parameters. The focal mechanism, depth, and proximity of the mainshock to the New York-Alabama magnetic lineament, a subsurface, crustalscale structure that spatially correlates with central ETSZ seismicity, suggest that this earthquake may share the same type of causal geologic structures as the more-active ETSZ region to the south.
