Monitoring Present-day Tectonic Motion in Papua New Guinea
The Geodynamics Group has been involved in a major long-term project to measure and
model present-day tectonic motion in Papua New Guinea since the first GPS surveys
there in 1990. The program is run in cooperation with the National Mapping Bureau,
the Papua New Guinea University of Technology, Lae and the Rabaul Volcano Observatory.
The monitoring network spans almost the entire country with particular dense network
across the South Bismarck/Pacific Plate boundary in New Ireland and east New Britain.
A similar program is being conducted in the Ramu-Markham Valley region by researchers
at the University of California, Santa Cruz.

WL: Woodlark Plate; SB: South Bismarck Plate.
Major field campaigns using modern P-code receivers have been conducted
in 1996 and 1998 with additional site occupations each year since 1997. Velocities
have been estimated at over 20 sites, leading to a first-order tectonic model for
the region (Tregoning et al., 1998).
Current research is concentrating on:
identifying the deformation field between the South Bismarck and Pacific Plates
measuring the velocity field along the northern coastline of New Guinea and throughout
establishing a monitoring network across the western end of the Bismarck Sea Seismic Lineation
