Cabled Seafloor Observatory

The project will build a multidisciplinary seafloor and water column observatory to monitor the on-going, submarine seismo-volcanic crisis that started in May 2018 offshore Mayotte (Feuilletal, 2021). The persistent seismic activity, together with the associated deformation field, indicate a potential for a migration of the eruptive activity to the west, that could expose the 290 000 inhabitants of Mayotte to considerable risks (see more in REVOSIMA). The Mayotte observatory system will allow permanent, real-time monitoring of the seismo-volcanic activity and serve as a multi-disciplinary platform for cutting edge research, not only in geoscience, but also on the evolution of marine ecosystems in response to large-scale, deep-sea eruptions.
