The USGS provided the following tectonic summary:

The May 14, 2019, M 7.5 earthquake in the New Ireland region of Papua New Guinea occurred as the result of shallow strike-slip faulting within the interior of the Pacific plate. Focal mechanism solutions for the earthquake indicate that rupture occurred on either a right-lateral northeast striking or a left-lateral southeast-striking fault. In this region, the Australia plate moves to the east-northeast with respect to the Pacific plate at a velocity of about 105 mm/yr. At the location of the earthquake, some researchers consider the edges of the Australia and Pacific plates to be divided into several microplates that take up the overall convergence between Australia and the Pacific, including the Solomon Sea, South Bismark, and Manus microplates near this event. In this context, the May 14th event occurred along the boundary between the South Bismark and Manus microplates. This fault structure was also the location of a M 8.0 earthquake in November 2000.
