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.

PIS将调查新不列颠海岸的海底建筑物坍塌沉积物和相关的海啸沉积物。投资促进机构建议绘制火山弧近海碎片沉积和沿海海啸沉积的地图、日期和特征，并利用这些数据模拟坍塌引发的海啸。建筑物倒塌在巴布亚新几内亚经常发生，包括1888年在里特岛发生的有充分记录的事件。所获得的知识最终可能导致预测类似构造区域未来发生的事件对沿海的影响。
