Understanding of slow and ordinary earthquakes in a single framework of modeling

We successfully simulate slow and ordinary earthquake in a single framework of modeling. It has become clear that key elements in the simulation are effects of fluid flow on fault slip and pore creation on the fault. We found that slower fault growth is obtained if we assume smaller permeabilities or larger pore creation rates. We also found that nonvolcanic tremor can be simulated if pore creation rate is large enough. Our calculation actually shows that fluid flow parallel to a fault must be assumed to simulate backward migration speeds of tremors on the order of 10-100km/h.
