| description |
<jats:p>Interactions between pore pressure, strain and seismicity were analyzed in a 30‐m‐thick shallow fault zone that was subjected to a small overpressure of 80 kPa to produce small changes in effective stress. Simultaneous pressure‐strain and seismic measurements taken in the fractured damage zone during the pressurization indicated that seismicity is triggered along low‐permeable, highly rigid, low‐dip angle, mesoscale‐inherited fractures where deformation is controlled by the hydromechanical behavior of the surrounding high‐permeability, not‐so‐rigid, aseismic, sub‐vertical, fault‐related fractures. Using a three‐dimensional distinct‐element representation of the fractures network, we show that the seismicity observed is mainly due to shear‐slip along inherited planes in response to the mechanical loading induced by the opening by a few microns of the surrounding subfaults.</jats:p> |
