Table 1. Time windows used for correlation analysis, the number of cluster events, and S-P times estimated from the Togi seismic station for E2, E3, E4, E5, E6, and E8. Parentheses denote the numbers of the members in the cluster when events whose cross-correlation coefficients were higher for other clusters are excluded. Note that the E2 cluster includes E1 while E7 and E9 belong to the E8 cluster.
