| Abstract: | Evolution of horizontal displacement of nodes at the internal side of a fault is modeled numerically by use of FLAC 3D，and distribution and evolution of regions where the sign of horizontal or vertical displacement of monitored nodes changes are also presented，based on the proposed heterogeneous and strain softening constitutive model.Result indicates that the reverse displacement phenomenon occurs during the jog failure for both echelon faults.However，the reverse displacement regions differ greatly for different echelon faults.For extensional echelon faults，the regions are large，and basically distribute outside the jog.For compressive echelon faults，the regions only locate in the jog and its adjacent faults. |
| Keywords: | echelon fault reverse displacement seismic precursor abnormality departure of precursors |
