Bulletin of the Seismological Society of America (2021) 111 (2): 1032–1042.
... Aperture Radar (SAR) images to calculate the 3D coseismic displacement of the 2018 Papua New Guinea earthquake. The results show clear fault traces that suggest coseismic slip on the Mubi fault and the Mananda fault that triggered landslides that spread out in a more than 260 km 2 region. Finite‐source...

... Abstract Cross sections, seismic data and centrifuge analogue modelling reveal the structural styles in the oil-producing areas of the Papuan Fold Belt. They include inverted basement faults, detachment faults in the Jurassic section 1–2 km beneath the Neocomian Toro Sandstone reservoir...

... by limestones and quartzites. The Papuan margin was dissected by Mesozoic extensional faults, in part reactivated during Neogene compression, which created basement-involved anticlines or elevated plateaus in the Papuan fold belt. The sedimentary section in the fold belt is deformed into large ramp anticlines...

... are well reproduced, and the modeled section appears quantitatively predictive. The modeling demonstrates three major pathways for water: (1) topographically driven flow from the onset of mountain building; (2) deep updip basinal flux, flowing along the tilted reservoirs; and (3) across fault escape from...

...-faulted anticlines associated with a fold–thrust belt (FTB) ( Rickwood 1990 ). Most of these compressive structures were developed during the Pliocene onwards ( Phelps & Dension 1993 ; Cole et al. 2000 ; McConachie et al. 2000 ; Schofield 2000 ) and are still active today. Present-day activity...

... not worked well in the area because they rely on the identification of anomalous porosities, principally associated with overpressuring by rapid burial and undercompaction. In an area like PNG, tectonic activity and related faulting and fracturing are likely to have an overriding effect on pressure...
