  stress redistribution
The coupling of the dynamic stress redistribution and the heterogeneity at different scales result in an inverse cascade of damage cluster size, which represents rapid coalescence of damage at the catastrophe transition.
      
We found that as damage accumulates, there is a stronger and stronger nonlinear increase in stress and the stress redistribution distance.
      
Therefore, it is surmised that the longer-range stress redistribution resulting from damage in heterogeneous media may be a plausible mechanism governing main shocks.
      
The stress redistribution in the heterogeneous-brittle medium implies a longer-range interaction than that in an elastic medium.
