Stress changes resolved for a mechanism of tremor. Δσn represents the normal stress change, Δτ is the shear stress change in the slip direction, and ΔCFF is the Coulomb failure function change for the shear slip on the plate interface. a Simulated values at the location estimated by the median epicenter of background tremors are shown as solid lines, and those at the location close to CJIG are shown as dotted lines. b Values at a depth of 45 km estimated from the recorded waveforms beneath station CJIG. The vertical dashed lines in gray correspond to the large peaks of triggered tremors shown in Fig. 2
