Effects of Bulk Poroelasticity on Repeating Earthquake Sequences: Insights From Numerical Modeling
At seismogenic depths, faults and the surrounding rock are saturated with water. Fault slip induces volumetric strains in the bulk, causing compression or dilation of pore fluid, which alters pore pressure—a phenomenon known as the poroelastic effect. This pore pressure change can, in turn, influence fault slip behav...
