Fig. 6: Compiled data plot of the relative permeability change versus frictional stability.
From: Coupled evolution of seismicity and permeability in fault zones
All data are derived from velocity increase steps, except for the translucent inverted triangles, which are derived from velocity decrease steps. Relative permeability change is approximately negatively correlated with frictional stability when shear velocity is increasing, with outlier points related to factors such as roughness and fluid pressurization due to fluid injection.
