Origin times of events a, b, A, B, and C were 10:02:45 JST on November 17, 2017, 19:56:05 JST on August 6, 2018, 19:23:01 JST on August 4, 2019, 03:23:54 JST on January 3, 2020, and 20:19:56 JST on February 6, 2020, respectively. Source durations were assumed using the empirical relationship between seismic moments and durations (Kanamori and Brodsky 2004)
