a Vertical cross-section of the P value distribution along the fault plane. The shaded area shows a block where the number of moment tensors used in the analysis is less than 10 in either period (2000 or 2017). The pink dashed line indicates the contour line of co-seismic slip larger than 2.5 m, from Iwata et al. (2002). The star indicates the location of the W-Tottori EQ hypocenter. The activity that preceded the W-Tottori EQ from Shibutani et al. (2002) is plotted as open circles. b The 90% confidence interval of the inelastic strain rate distribution for the period in 2000 (left) and in 2017–2018 (right). Other symbols are the same as in Fig. 7a
