2015 M6.4 Iliamna Earthquake
This earthquake occurred in the downgoing portion of the subducting Pacific Plate. The Aleutian trench marks the boundary between the subducting Pacific and overriding North American plates in southern Alaska and the Aleutian islands.
The moment tensor solutions for this event indicate reverse faulting. The faulting type of this earthquake is consistent with down dip extension of the Pacific Plate as it is pulled into the mantle under its own weight.
