Present-day crustal motion in Papua New Guinea

Papua New Guinea is one of the most active tectonic regions in the world. I t comprises several microplates and deforming zones trapped in the collisio n of the Australian and Pacific Plates. GPS observations have been used to estimate plate velocities across a network of sites spanning most of the co untry. We present new velocites in the northwestern region of New Guinea, a nd look in detail at the strain accumulation region between the South Bisma rck and Pacific Plates in the New Ireland/New Britain region.
