The March 29, 2015 M 7.5 earthquake southeast of Kokopo, Papua New Guinea, occurred as the result of thrust faulting on or near the plate boundary interface between the subducting Australia and overriding Pacific plates.

At the location of the earthquake, the Australia plate moves towards the east-northeast at the velocity of 105 mm/yr with respect to the Pacific plate, beginning its subduction into the mantle beneath New Britain and New Ireland at the New Britain Trench south of the earthquake. The moment tensor and depth of the event are consistent with thrust-type motion on the interface between the two plates.
