This project is based on recently acquired seafloor samples and geophysical data from extraordinary deposits at a modern submarine volcano. This project aims to determine the conditions that lead to explosive eruption underwater, the dynamics of associated sediment flows, and if these events can trigger tsunami. Expected outcomes include an unprecedented reconstruction of the architecture of submarine caldera volcanoes, new innovative models applicable globally for a richer understanding of volcanic tsunami and eruptions that shape the seafloor. This project will provide significant benefits through mitigation of global marine natural hazards, and by improving knowledge on the volcanic hosts of ore deposits.

该项目的基础是最近从现代海底火山的异常沉积物中获得的海底样品和地球物理数据。该项目旨在确定导致水下爆炸性喷发的条件，相关沉积物流动的动力学，以及这些事件是否会引发海啸。预期成果包括前所未有地重建海底破火山口的结构，适用于全球的新的创新模型，以更丰富地了解塑造海底的火山海啸和喷发。该项目将通过减轻全球海洋自然灾害和增进对矿床火山宿主的了解，带来重大惠益。
