Collaborative Research: Stratovolcano lateral collapses and collapse-generated tsunamis in island arc settings: the example of the North New Guinea Arc

pi将调查新不列颠海岸外的海底大厦崩塌沉积物和相关的海啸沉积物。pi建议绘制、确定日期并描述火山弧中的近海碎屑沉积物和沿海海啸沉积物，并使用这些数据来模拟崩塌引发的海啸。建筑物倒塌已被证明是巴布亚新几内亚经常发生的事件，包括1888年里特岛的事件。所获得的知识最终可以用于预测类似构造区域未来事件对沿海地区的影响。

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.
