Aftershocks and Omori's law in a modified Carlson-Langer model with nonlinear visco-elasticity
arXiv:1505.02225 · doi:10.1103/PhysRevE.91.052914
Abstract
A modified Carlson-Langer model for earthquakes is proposed, which includes nonlinear visco-elasticity. Several aftershocks are generated after the main shock owing to the damping of the additional visco-elastic force. Both the Gutenberg-Richter law and Omori's law are reproduced in a numerical simulation of the modified Carlson-Langer model on a critical percolation cluster of a square lattice.
