Number of clusters versus horizontal distance for three lapsed times for the NIED F-net catalog. Solid lines represent the results obtained from analyses of real data and dotted lines are those from a simulated data catalog. a \({M}_{w}\) 5.0–5.5, b \({M}_{w}\) 4.5–5.0, and c \({M}_{w}\) 4.0–4.5. c = 3 and \({t}_{d}\) = 1825 days are used. Arrows indicate the triggering distances (see the text). Note that the ranges of the horizontal axes are different for (a)–(c)
