Numerical Simulations of Earthquake Cycles Using Depth-Dependent Frictional Parameters Laarni S. dela Cruz and Kazuro Hirahara. August 2012 p. 26-32 Numerical simulations of earthquake cycles using a rate- and state-dependent friction law were performed on a segmented strike-slip fault such as the Philippine Fault Zone in Luzon. Frictional parameters were assigned to characterize stable and unstable zones along depth. The effect of normal stress history was also considered to provide some insights on the mechanics of earthquake cycles. The time evolution of shear stress, slip velocity, frictional coefficient, a state variable and displacement are calculated using a fifth-order Runge-Kutta method with an adaptive time step. Time histories of shear stress in the seismogenic zone over the entire duration of simulation were used to analyze fault interactions and seismically active periods obtained from the simulations.
