Exhumed subduction zones and geophysical imaging have shown that the seismogenic subduction interface is a deformed, 100m-1km thick tabular region. Within this region, we currently do not know if seismic slip is localized on a single fault or distributed over several active faults, and how this impacts seismogenesis and the timing and style of...

The simplified view of the subduction interface is that of a single plane along which seismic and aseismic deformation occurs. In reality, however, exhumed subduction zones and geophysical imaging have shown that the seismogenic plate interface is a deformed, 100m-1km thick tabular region. Within this region, we currently do not know if seismic...

The 2016 Mw 7.8 Pedernales, Ecuador, earthquake rupture area was accompanied by aseismic slip at shallower depth such as slow earthquake and post-seismic slow slip. In addition, the relatively small forearc and shallow megathrust along the Ecuadorian margin makes it an exceptional natural laboratory to study the link between the ongoing...

Subduction zones generate the largest earthquakes on Earth, yet their detailed structure, and its influence on seismic and aseismic slip, remains poorly understood. Geological studies of fossil subduction zones characterize the seismogenic interface as a 100 m–1 km thick zone 1–3 in which deformation occurs mostly on metres-thick faults 1,3–6 ....

Identifying the circulation of fluids in subduction zone system and understanding their role on the megathrust fault slip modes remains one of the outstanding challenges in Earth Sciences. As these faults have the capacity to generate mega-earthquakes, the associated hazard to the society is significant.In recent years, studies in Japan, Costa...
