The paper reports systematic pre-rupture increases in Shannon and Tsallis entropy paired with decreasing EWH, abrupt co-seismic shifts, and persistent post-seismic anomalies interpreted as fault system criticality and non-equilibrium states.
Coupled CFD-DEM simulations show frictional instability arises from coupled evolution of pore pressure, drainage, dilation/compaction, hydraulic connectivity, and granular fabric rather than pore pressure alone.
