Location map of the seismic stations used in this study. The left and right diagrams show the San-in region and the northern Kinki region, respectively. Cross marks are temporary stations (250 Hz) and open circles are permanent stations (100 Hz). In the San-in and northern Kinki regions, the numbers of temporary stations are 131 and 42, respectively, and those of permanent stations are 90 and 78, respectively. Small blue and pink dots are epicenters determined by the San-in and northern Kinki seismic networks, respectively, for the period from October 2014 to March 2016 in San-in and from April 2016 to September 2016 in northern Kinki. In the determination of the epicenters, both the permanent and temporary stations are used
