Tectonics in this region is defined by ongoing collision of the Yakutat block with the North American plate. Complex system of thrust and strike-slip faults define boundary between these two tectonic members. High rates of mountain building and crustal uplift are present in this region, especially in the corner syntax where the strike-slip Fairweather fault connects into the Chugach-Saint Elias thrust fault and fold belt.

The elastic-wave radiation pattern of the M6.0 event indicates oblique strike-slip faulting consistent with rotational motion of the Yakutat block with respect to the North American plate.
