Paper Title:
Numerical Studies of the Influence of Heterogeneity on Rock Failure and Induced Earthquake Precursors
  Abstract

A series of numerical simulations were performed to investigate the effects of geometric and mechanical heterogeneity of pre-existing faults of rocks on their failure and induced earthquake precursors. The numerical results revealed that rock failures with the different heterogeneity produce the different earthquake precursors, which are in a good agreement with those of observations in nature.
