Figure 5

Correlation diagram between the amount of strain accumulated before the Bungo Channel L-SSE (2) (7 February 2011–19 April 2018) and the amount of change in strain during the L-SSE occurrence (20 April 2018–26 May 2019). The values of the dilatation and the maximum shear strain at the calculation points shown in Fig. S2d are used. The expressions of the figures are the same as those in Fig. 3a and b.
