Realistic spatial and temporal earthquake distributions in a modified Olami-Feder-Christiensen model
arXiv:0905.0421 · doi:10.1103/PhysRevE.81.046117
Abstract
We propose and study a modified version of the Olami-Feder-Christiensen model of seismicity, that includes a mechanism of structural relaxation. We obtain realistic features of seismicity that are not obtained with the original version, mainly: aftershocks that obey the Omori law and cluster spatially around the slip surface of the main shock, and averaged frictional properties qualitatively similar to those observed in rock friction, in particular the velocity weakening effect.
