Earthquake geology of New Guinea
Research efforts to date in New Guinea have relied upon the use of coarse-resolution topographic data and sparse geodetic data. Nonetheless, most of the neotectonic features have been mapped, and the overall earthquake geology of the island is being unravelled.
To first order, the local tectonic context results from the rapid, oblique west-southwest convergence of the Australian and Pacific plates at a rate of about 110 mm/yr. A closer look however reveals a vastly more complex set of converging, diverging and translating lesser plates. High levels of seismicity throughout New Guinea indicate ongoing tectonic deformation, which makes the island a crucial target for tectonic research. Integration of EOS observations with bathymetric, seismic and geodetic data of other institutes is ongoing.
