All Fiber optic sensing (DAS) Ocean Earthquakes Other

Using Distributed Acoustic Sensing (DAS) on existing seafloor fiber optic cables to monitor ocean processes such as temperature, wave heights or seafloor currents.

AI and fiber optic sensing for smart territories

Exploiting fiber optic cable to scrutinize natural hazards

Outer-rise seismicity

Outer-rise earthquakes occur in the oceanic plate just before it enters the subduction zone. We investigate this particular type of seismicity to understand its link to the subduction.

E-POST stands for Early-POSTseismic. The project aims at better understanding the transition between the coseismic (the rupture) and the processes immediately following (like afterslip). This is an ANR funded project led by M.Vergnolle.
