Analysis of Earthquake Hazard in Papua New Guinea

After an understanding of the regional seismicity and tectonics has been gained, the second stage for an earthquake hazard study is largely concerned with calculation of ground motion recurrence, representing the hazard due to shaking by seismic waves. Other earthquake hazards, such as liquefaction, surface rupture, landslides, and tsunami, are treated separately. Two main models required to compute ground motion recurrence are a seismotectonic model that specifies the assumed distribution of earthquake magnitude recurrence of earthquakes, and a ground motion model that specifies the expected ground motion from the earthquakes.
