Abstract
In this study, using modelled seismic sources and assigned ground-motion equations, the level of seismic hazard in terms of Peak Ground Acceleration (PGA) was calculated for return period of 475 years. The calculations were performed for bedrock site conditions (Vs30=760 m/s). From the results it is evident that the seismic hazard reaches to its maximum level (i.e. PGA-1g for 475 yr return period) at the Huon Peninsula and southern New Britain regions. Disaggregation analysis revealed that moderate to large earthquakes occurring along the New Britain Trench mainly control the level of hazard at these locations. For the seismic hazard computations, the open-source computer program OpenQuake developed by Global Earthquake Model foundation (http://www.globalquakemodel.org/openquake) was used. It should be emphasized that the presented results are still preliminary and should not be interpreted as our final assessment of seismic hazard in PNG.
