Determination of Parameters Characteristic of Dynamic Weakening Mechanisms During Seismic Faulting in Cohesive Rocks

Cornelio, C. Spagnuolo, E. Aretusini, S.

While sliding at seismic slip-rates of ∼1 m/s, natural faults undergo an abrupt decrease of shear stress called dynamic weakening. Asperity-scale (<neff = 5-40 MPa), target slip-rate (Vt = 0.1-6.5 m/s) and fluid pressure (Pf = 0-15 MPa). To account for the uncertainties of constitutive parameters, we introduce a norm-based optimization...
