Figure 5

(a) The Q_s^–1 and Q_i^–1 value of the BEP (blue and brown, respectively) and AEP (violet and orange, respectively) are compared for the stations. All (BEP + AEP) of Q_s^–1 and Q_i^–1 value is also plotted as blue and brown open triangles, respectively. The common logarithm of Q_s^–1 value multiplied by 10³, AEP-BEP, are divided by dotted line as 5 largest (plus) and 5 smallest (minus) ones. The error bars are based on Fisher’s F distribution with a confidence of 60%. (b–d) Topographic maps showing the difference between the BEP and AEP (AEP-BEP) for the Q_s^–1, Q_i^–1, and Q_t^–1 value, respectively, of the Kumamoto earthquake at 1.5 Hz. Focal mechanism of mainshock in (d) is from CMT catalog from Hi-net (https://www.hinet.bosai.go.jp/AQUA/aqua_catalogue.php?LANG=en). The other symbols are the same as those in Fig. 2.
