Exploiting fiber optic cable to instrument oceans

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.
