Analysis of the inelastic cumulative seismic ($\sum \mathrm{\Delta }{ϵ}^{\mathit{AE}}$) to inelastic asiesmic deformation ($\mathrm{\Delta }{ϵ}^a$) leading up to failure. Details to the calculations are given in Section Aseismic and seismic inelastic volumetric deformation. (a) The activated volume $V_{\mathit{act}}$ determined by the cluster analysis. The inset images show the volume capturing 100th percentile (green, solid line) and 95th percentile (gold, dashed-line) for two random sub-catalog in time. (b) A shear (red lines, Eq. 9) and isotropic (blue lines, Eq. 10) models are used as end-member estimates for volumetric strain changes from the source. The dashed and solid lines represent the calculations made for the 95th and 100th percentile of activated volume. (c) The total inelastic strain ($\mathrm{\Delta }{ϵ}^{\mathit{DSS}}$) computed using the DSS measurements. (d) The inelastic seismic-to-aseismic ratio ($\gamma$, see Eq. 11) using only the isotropic source, since we are unable to measure the shear deformation using the implemented DSS configuration.
