Seismic hazard mapping of Papua New Guinea — 2019 revision

In this study, we performed a probabilistic seismic hazard assessment (PSHA) for Papua New Guinea (Figure 1) to underpin a revision of the seismic zoning map for the national building code of PNG (Figure 2).  
To perform PSHA, we compiled a composite catalogue for the period of 1900-2017 (Figure 3). We then developed magnitude conversion equations to homogenize the catalogue in terms of moment magnitude scale (M W , Figure 4).
In contrast to previous studies in PNG (e.g. Ghasemi et. al, 2016), we developed a seismotectonic model that includes 18 fault models (Figure 5) combined with the distributed seismicity (Figure 6) to model earthquake sources.
Following the classical PSHA methodology, we mapped the seismic hazard in terms of peak ground acceleration (PGA) with 10% probability of exceedance in 50 years (Figure 1). We also computed hazard curves (Figure 7) and uniform hazard spectra (Figure 8) at the location of major population centres in PNG (black circles in Figure 1). 
Results of this study indicate a high level of hazard in the coastal areas of Huon Peninsula and New Britain–Bougainville regions and a relatively low level of hazard in the southwestern part of Papua New Guinea. 
To identify earthquake sources that are contributing most to the overall hazard, we performed hazard disaggregation analysis for all of the major localities in PNG (e.g. Figure 9).
Results of the hazard disaggregation analysis shows that in the Huon Peninsula region, the frequent moderate to large earthquakes occurring on the Ramu-Markham Fault Zone results in high seismic hazard (Figure 9). The New Britain–Bougainville region also has relatively high seismic hazard. The proximity to the subduction zone of the New Britain Trench is the main influence on the calculated level of hazard

Great Barrier Reef  Banks

Geomorphic banks were mapped in this study based on a GIS analysis of a 100 m bathymetry grid for the Great Barrier Reef produced by Beaman (2010).  The bathymetric data were contoured at 5 m intervals and used to interpret the location of geomorphic bank features, defined as having at least one steep (i.e. greater than ~2 degrees) slope rising more than 15 m above the level of surrounding seafloor.  All banks were digitised by hand aided using three-dimensional imagery.  Bank polygons were created in ArcGIS with the base of slope taken as the outer edge of the bank.  Mean bank elevation estimates thus include the bank slopes as well as planar bank-tops.  Only banks occurring on the continental shelf of the Great Barrier Reef between the 20 and 200 m isobaths, and between the latitudes of 10 to 25Â° S were included.

GSNSW Exploration NSW Area R Enngonia magnetic rtp grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This magnetic grid has a cell size of 0.00077 degrees (approximately 80m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2001 by the NSW Government, and consisted of 34611 line-kilometres of data at 400m line spacing and 80m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

The upper crustal geology of the Georgina Basin region

Pattern recognition in regional maps of Bouguer anomalies and total magnetic intensity contours suggests that the basement of the Georgina Basin can be divided into four regions, three of which contain subsurface extensions of the Tennant Creek Inlier, Arunta Inlier and Mount Isa Orogen-South Nicholson Basin (sensu Plumb. in press), and a fourth in the south, for which there is no known outcrop and whose composition differs from the others. The boundaries between these regions are in most cases not visible in outcrop. The basement to the Georgina Basin thus consists predominantly of metamorphic rocks and granites inferred to be similar to the outcrop areas which surround it. This is overlain by Adelaidean and Phanerozoic sediments, which locally are up to 8000 m thick. With the exception of the Toko Syncline, Dulcie Syncline, Lander Trough and Burke River Structure, where up to 3500 m of Palaeozoic sediments are preserved, only a thin veneer up to 500 m thick of Phanerozoic sediments occurs in the basin. However, considerable thicknesses of possible Adelaidean sediments are interpreted to occur both beneath these structures and locally elsewhere, for example 3000 m in the Toko Syncline, 4000 m near Camooweal (this figure may include older Carpentarian rocks), and 6000 m in the Glenormiston-Sandover River area. A geological history for the basement of the area is proposed, which provides a framework for subsequent deposition in the Georgina Basin. An important suggestion is that there was extensive thrusting to the northeast of the Arunta Inlier rocks at about 1000 m.y. - which produced scalloped thrusts, some of which may cut Mount Isa Orogen rocks. It is inferred that thick Adelaidean sediments were subsequently deposited in graben with active margins along these thrusts, and later, after a brief hiatus, a similar reactivation was accompanied by Palaeozoic sedimentation.
