- •
Fault structures and stratigraphy influence fault-related fluid circulation.
- •
Between ∼3 and ∼1 km depths marine-derived fluids circulated within the fault zone.
- •
At depths ≤1 km meteoric-derived fluids infiltrated into the fault zone.
- •
Fluids were redistributed at hydrostatic pressure following co-seismic dilatancy.
- •
Only the principal fault has been characterized by fluid overpressures.
