Submarine landslide tsunamis, mechanisms of granular flows at multiple scales; a new UK/China multidisciplinary research collaboration

在过去的20年里，地质学家和数值模型师之间的国际合作对海底滑坡引起的海啸有了更好的理解。斯托雷加和大浅滩等大型平移海底山体滑坡引发的海啸不太为人所知，因为其复杂的内部变形在失败后，很难在海啸产生的背景下建模和理解。因此，这项建议的目的是通过国际合作，汇聚在海底滑坡海啸方面具有专门知识的地质学家和研究新海洋背景下空中颗粒沉积物流动的数值模型师，这将有助于更好地了解海啸产生过程中海底平移沉积物运动的物理学。这些海底滑坡海啸对英国(例如北海)和中国(在南中国海)都是一种危险。为了解决这些复杂的机制，该项目旨在英国地质调查局和爱丁堡大学的英国研究人员与同济大学的中国研究人员之间建立新的合作伙伴关系。我们的愿景是通过跨学科合作在粒子、连续统和场尺度上融合关键机制，从根本上提高模型的可预测性和适用性。

Over the past 20 years tsunamis from submarine landslides, such as slumps and blocks, have become better understood from international collaborations between geologists and numerical modelers. Tsunamis from large volume translational submarine landslides such as Storegga and Grand Banks are less well understood because their complex internal deformations, on failing, are challenging to model and understand in the context of tsunami generation. The objective of this proposal, therefore, is to bring together geologists with expertise in submarine landslide tsunamis and numerical modelers who research subaerial granular sediment flows in a new marine context through an international collaboration which will lead to a better understanding of the physics of submarine translational sediment movement in the generation of tsunamis. These submarine landslide tsunamis are a hazard to both the UK (e.g. the North Sea) and China (in the South China Sea). To address their complex mechanisms the project aims to establish new partnerships between UK researchers from the British Geological Survey and the University of Edinburgh and Chinese researchers from Tongji University. Our vision is to radically improve model predictability and applicability through fusing critical mechanisms at the particle, continuum and field scales, enabled by transdisciplinary collaborations.
