dissipated within a smaller time frame compare to the time step used in this study. To

examine another possible mechanism for episodic fluid flow, a bulk permeability-vertical

stress relationship was assigned to the decollement. Results indicate that excess pore

pressures close to lithostatic can be sustained at the base of the prism while fluid is

expelled at the toe of the complex. This further suggest that decollement may not need to

hydrofracture initiating transient lateral fluid flow because the bulk permeability-vertical

effective stress relationship could propagate fluid pulses towards the toe of the complex

releasing fluids at the toe of the prism. However, the effects of vertical hydrofracture and

assigning the bulk permeability-effective stress relationship in the decollement should be

further investigated at smaller time steps to examine if episodic events occur in the

decollement.
