22 showed that the Coulomb stress change (ΔCFF) around the Kamaishi mine exhibited a positive trend after the Tohoku-oki earthquake, and Bletery et al . 36 demonstrated that the stress drop altered to a negative trend after the mainshock (see Supplementary Figure 8 ).

36 demonstrated that the stress drop altered to a negative trend after the mainshock (see Supplementary Figure 8 ).
As with the three principal stresses, the magnitude of the maximum shear stress increased as a result of the Tohoku-oki mainshock, decreased until 3 years after the earthquake and subsequently returned to an increasing trend 5 years after the earthquake.
