The quakes seem to be strung out parallel to the trench. The SE-striking nodal plane of the M7.7 is right-lateral. I recall that subduction in that corner of the Pacific Plate is highly oblique, and the strike-slip component would be right-lateral. The oblique slip "partitions" into thrust on the subduction zone and right-lateral above it.
Seems like Plate Tectonics and structural geology work.
