The aim of this project is to improve our understanding of the mechanics of the spreading failure and the geological control of spreading in the submarine environment, in particular by using geophysical techniques, geomorphometry, numerical modelling, core sediment analysis and geotechnical tests. The project has the following specific objectives:
SO1 Identify the topographic and sedimentary signatures of submarine spreading
SO2 Understand the trigger mechanisms and development process of a submarine spread
SO3 Test whether topographic and sedimentary signatures of spreading can be used as a palaeoseismic proxy.
Results will have the potential to be integrated into future palaeoseismic and geohazard frameworks to improve the seismic and ground failure hazard assessment at a specific site. The outcomes from this research project in terms of landslide processes and palaesoeismic information will have broad application in the wider geoscientific and engineering communities in terms of building more resilient urban communities to seismic and co-seismic processes. The geohazards component will complement the project, giving it an overarching perspective. The proposed research work is aligned with current research projects designed for exploring the submarine palaeoseismicity in the Japanese trench (ECORD 386), and with European research infrastructures aimed at improving our understanding and prediction of offshore slope failures, and the seismic hazard and risks worldwide.
