The PIs will investigate submarine edifice-collapse deposits off the coast of New Britain and related tsunami deposits. The PIs propose to map, date and characterize offshore debris deposits and coastal tsunami deposits in the volcanic arc and to use these data to model collapse-generated tsunamis. Edifice collapse has been shown to have been a frequent occurrence in Papua New Guinea, including the well-documented 1888 event at Ritter Island. Knowledge gained could ultimately lead to prediction of coastal impacts from future events in similar tectonic areas.

PI将调查新不列颠海岸的海底建筑物倒塌沉积物和相关的海啸沉积物。研究所提议绘制火山弧中的近海碎屑沉积物和沿海海啸沉积物的地图、测定其年代和特性，并利用这些数据模拟海啸。在巴布亚新几内亚，埃迪亚火山的崩塌已被证明是经常发生的，包括1888年在里特岛发生的有据可查的事件。所获得的知识最终可用于预测类似构造地区未来事件对沿海的影响。
