Abstract Papua New Guinea (PNG) lies in a belt of intense tectonic activity that experiences high levels of seismicity. Although this seismicity poses significant risks to society, the Building Code of PNG and its underpinning seismic loading requirements have not been revised since 1982. This study aims to partially address this gap by updating the seismic zoning map on which the earthquake loading component of the building code is based. We performed a new probabilistic seismic hazard assessment for PNG using the OpenQuake software developed by the Global Earthquake Model Foundation (Pagani et al. in Seism Res Lett 85(3):692–702, 2014). Among other enhancements, for the first time together with background sources, individual fault sources are implemented to represent active major and microplate boundaries in the region to better constrain the earthquake-rate and seismic-source models. The seismic-source model also models intraslab, Wadati–Benioff zone seismicity in a more realistic way using a continuous slab volume to constrain the finite ruptures of such events. The results suggest a high level of hazard in the coastal areas of the Huon Peninsula and the New Britain–Bougainville region, and a relatively low level of hazard in the southwestern part of mainland PNG. In comparison with the seismic zonation map in the current design standard, it can be noted that the spatial distribution of seismic hazard used for building design does not match the bedrock hazard distribution of this study. In particular, the high seismic hazard of the Huon Peninsula in the revised assessment is not captured in the current building code of PNG.

<p><strong>Abstract.</strong> West New Britain Province, which occupies the western part of New Britain Island in Papua New Guinea, is ideally located within an active tectonic region that influences volcanism creating an environment favourable for geothermal activity. Geothermal mapping of surface manifestations reveals high temperature geothermal prospects along the northern coastline of West New Britain Province that are further confirmed by geochemical analysis. The occurrence of geothermal features is confined to the Quaternary Kimbe Volcanics and alluvium in the lowland areas. The features in Talasea appear to be controlled by deep-seated northerly trending faults while structures in Hoskins also appear to be deep seated but have not been identified. The geothermal systems in West New Britain Province have not been drilled, but preliminary reconnaissance geothermal mapping and geochemical analysis reveals four high temperature geothermal prospects suitable for further investigation and development of geothermal energy. These are the Pangalu (Rabili) and Talasea Station geothermal prospects in Talasea and Kasiloli (Magouru) and Silanga (Bakama and Sakalu) geothermal prospects in Hoskins. The calculated reservoir temperatures for these fields are in the range of 245–310 °C. Recommendations are made for further follow-up exploratory investigations.</p>

In the Papuan thrust belt the main risk in hydrocarbon exploration lies in identifying structural traps which are detached below the level of the primary reservoir. Because of the difficulty in obtaining usable seismic in the remote, inaccessible terrain, identification of prospects has been based on the interpretation of structural cross-sections drawn from geological maps. The structural models commonly used have been geometrically inadmissible, and as a result, some wells have penetrated thrusts at depth, before reaching the reservoir horizon.More rigorously constrained regional cross sections through the thrust belt may be constructed using the principles of thin skinned tectonics. These may be used to identify structural provinces, characterised by different types of thrust pattern. In turn, the probability of reservoir involvement in a particular structure is directly related to its location in a particular province.The cross-sections show that there has been as much as 100 km of shortening in the hinterland of the thrust belt. Restored versions of the cross sections may be used to reconstruct the shape of the basin and ideally to identify regions favourable for source and reservoir sediment distribution. In Papua New Guinea, palinspastic maps are currently feasible only for Miocene strata, but with the present level of exploration activity increased stratigraphic information should soon permit reconstructions for older formations.

AbstractThe small waterstriders of the subfamily Trepobatinae have radiated extensively on New Guinea and surrounding archipelagos. The present contribution is the sixth in a series of reports dealing with this endemic fauna, and presents a cladistic analysis at the generic level for the subfamily, a biogeographic analysis, a world checklist, a complete bibliography, and final taxonomic addenda. The taxonomic appendix contains new distributional records for Stygiobates mubi Polhemus & Polhemus, and descriptions of the following new taxa: the new genus Talaudia to hold the previously described Andersenella nilsi Chen & Nieser from the Talaud Archipelago; Metrobatoides bifurcatus sp. n. from northern central Irian Jaya; and Iobates ivimka sp. n. from southern Papua New Guinea. The current cladistic analysis supports the previously proposed tribal classification, with the Metrobatini, Trepobatini, Naboandelini, and Stenobatini all resolved as discrete monophyletic groups. Our cladistic and biogeographic analyses also suggest that the current distribution of trepobatine genera in the New Guinea region has been strongly influenced by past tectonic events, most notably the accretion of island arc terranes derived from the Solomons and Halmahera arc systems. This has led to distinct areas of freshwater and marine endemism among the Metrobatini and Stenobatini in the areas surrounding Halmahera, the Vogelkop Peninsula, and northeastern New Guinea plus nearby islands. By contrast, the distribution of Naboandelini in the New Guinea region suggests a vicariance pattern with Australia across the Torres Strait.

Veined peridotite xenoliths from the mantle beneath the giant Ladolam gold deposit on Lihir Island, Papua New Guinea, are 2 to 800 times more enriched in copper, gold, platinum, and palladium than surrounding depleted arc mantle. Gold ores have osmium isotope compositions similar to those of the underlying subduction-modified mantle peridotite source region, indicating that the primary origin of the metals was the mantle. Because the mantle is relatively depleted in gold, copper, and palladium, tectonic processes that enhance the advective transport and concentration of these fluid soluble metals may be a prerequisite for generating porphyry-epithermal copper-gold deposits.

A Mw 7.1 earthquake off the north coast of New Guinea, generated a locally very destructive tsunami at 08:49 17th July 1998 UTC (6:49 PM local time). More than 2189 people died, and no structures were left standing along 19 km of coast. A reconnaissance team from the N.Z. Society for Earthquake Engineering visited the area a month after the event. Over three days, they examined effects of the tsunami on structures and landforms, measured profiles and sampled deposits. A fast moving wall of sand-laden water left fishing nets and other detritus in trees up to 17.5 m above sea level. Concrete was stripped to the reinforcing, and some trees were ripped out and carried more than a kilometre. The team saw evidence of new subsidence of -300-400 mm on the landward side of the spit fronting Sissano Lagoon. The site is in an active sedimentary basin, the Aitape Trough with 4,500-m thickness of Neogene sediments, between the Bewani fault zone and the Wewak Trench. The area may have subsided 3 times this century. In situ stumps of drowned trees in the lagoon record one of the earlier events. The low-angle Harvard University CMT solution (Mw 7.1, depth -6.0 km, -10° landward dip on fault with northward displacement) is consistent with the tectonic setting and pattern of aftershocks. Elastic modelling of the energy release with -2 m horizontal displacement over 600 km2, suggests -400 mm subsidence (landward) and -600 mm uplift (seaward in >3 km water depth). The team suggests that convergent flow of the displaced water into the area of subsidence focused wave energy on the coast and generated the locally very high wave. The spit fronting Sissano Lagoon is unsafe for habitation. There is potential for coseismic coastal subsidence to focus tsunami in other areas with similar tectonic settings. This potential suggests that both eastern and western New Zealand coasts have a serious hazard from local tsunami that is presently underestimated for the western coastline because of the lack of historical occurrences.

Airborne magnetic and radiometric datasets have, over the past few years, become powerful tools in the identification of porphyry systems which may host economic porphyry copper–gold–molybdenum ore bodies. Magnetisation contrasts with the unaltered host rocks, coupled with the elevated radiometric signature, compared to the host rock, makes identification of large-scale porphyry copper systems possible. Integrating these two different datasets with stream sediment data and other geochemical exploration methods results in a higher degree of confidence. Stream sediment data were analysed to see the distribution of copper and gold elements throughout the study area, located within the Eastern Papuan Peninsula of Papua New Guinea. Airborne geophysics data over the same area were also processed for magnetic and radiometric responses. The processing of the magnetic data revealed several magnetic anomalies related to concealed intrusive rock units, with associated radiometric signatures. The distribution of gold and copper anomalism was correlated with the geology and geophysical signatures. Results indicate varying degrees of correlation, with some areas showing a strong correlation between gold/copper occurrence and geophysical signatures, compared to other areas. Some factors that we believe impact the level of correlation may include tectonic history, volcanic cover, and weathering patterns. We recommend caution when applying multi-data exploration for porphyry copper systems.

Tsunamis are long waves that evolve substantially, through spatial and temporal spreading from their source region. Here, we introduce a new analytical solution to study the propagation of a finite strip source over constant depth using linear shallow-water wave theory. This solution is not only exact, but also general and allows the use of realistic initial waveforms such as N -waves. We show the existence of focusing points for N -wave-type initial displacements, i.e. points where unexpectedly large wave heights may be observed. We explain the effect of focusing from a strip source analytically, and explore it numerically. We observe focusing points using linear non-dispersive and linear dispersive theories, analytically; and nonlinear non-dispersive and weakly nonlinear weakly dispersive theories, numerically. We discuss geophysical implications of our solutions using the 17 July 1998 Papua New Guinea and the 17 July 2006 Java tsunamis as examples. Our results may also help to explain high run-up values observed during the 11 March 2011 Japan tsunami, which are otherwise not consistent with existing scaling relationships. We conclude that N -waves generated by tectonic displacements feature focusing points, which may significantly amplify run-up beyond what is often assumed from widely used scaling relationships.

Biogeographic connections between Australia and other continents are still poorly understood although the plate tectonics of the Indo-Pacific region is now well described. Eupetes macrocerus is an enigmatic taxon distributed in a small area on the Malay Peninsula and on Sumatra and Borneo. It has generally been associated with Ptilorrhoa in New Guinea on the other side of Wallace's Line, but a relationship with the West African Picathartes has also been suggested. Using three nuclear markers, we demonstrate that Eupetes is the sister taxon of the South African genus Chaetops , and their sister taxon in turn being Picathartes , with a divergence in the Eocene. Thus, this clade is distributed in remote corners of Africa and Asia, which makes the biogeographic history of these birds very intriguing. The most parsimonious explanation would be that they represent a relictual basal group in the Passerida clade established after a long-distance dispersal from the Australo-Papuan region to Africa. Many earlier taxonomic arrangements may have been based on assumptions about relationships with similar-looking forms in the same, or adjacent, biogeographic regions, and revisions with molecular data may uncover such cases of neglect of ancient relictual patterns reflecting past connections between the continents.

A four-well project located onshore Papua New Guinea provided an opportunity to compare the performance of two inhibitive drilling fluids in the problematic 12¼” interval. Wells A and B were drilled using a conventional KCl/glycol fluid. Wells C and D used a high-performance water-based fluid (HPWBF) containing a shale inhibitor that also provides lubricity. All four wells were drilled with the same rig. The base brine for both fluids was KCl. All hole sections were directionally drilled from vertical to near horizontal by section TD through a claystone interval. Tectonic wellbore breakout was present in all four wells, and the position of the breakout in the wellbore varied from well to well. Well A was regarded as the easiest well to drill due to the breakout being on the sides on the inclined well bore (horizontal), and Well D was regarded as being the most difficult well to drill due to the breakout being located directly on the top and bottom of the wellbore (vertical). Performance comparisons were made using on bottom rates of penetration, tripping times, casing running times, and overall hole section costs. These data have been normalised to remove non hole related NPT events. The KCl/glycol system provided sufficient wellbore stability in Wells A and B with horizontal breakouts and with non-optimal breakouts with very limited openhole exposure. For higher risk wells C and D with non-optimal breakout positions however, the HPWBF offered improved reliability and ensured there was no performance decline. Outstanding performance occurred in Well D where the HPWBF maintained good wellbore stability over a 56-day exposure. Although the KCl/glycol fluid had a lower cost/bbl, improved overall cost savings were achieved by using the HPWBF in the high-risk wells. This paper addresses all operations performed while drilling and casing the 12¼” interval. Possible causes for performance differences are evaluated, taking into account that mud systems represent only one variable. As other variables were introduced progressively, it was possible to back these out to determine mud system effectiveness.
