The Role of Fluid Pressure?Induced Aseismic Slip in Earthquake Cycle Modulation

The evolving state of fault stress during and after the perturbation fluid pressure gives rise to an intriguing interplay seismic aseismic slip on fault. A better understanding possible role fluids in triggering mechanism seismicity is pivotal effective hazard mitigation, particularly context induced seismicity. Through numerical modeling, we investigate effect pore perturbations spatio-temporal evolution modulation earthquake cycles. Pressure are imposed at different magnitudes times a selected interseismic period. Results show wide range responses which can lead both time advancement delay subsequent earthquakes. Specifically, even <5% average event drop trigger that leads considerable next when occurs late We find earthquakes delayed associated with large moment release. Our study highlights importance close monitoring regions prone influence provides physical insights into identifying critical certain outcomes.
