Fig. 3

Number of clusters versus horizontal distance for three lapsed times for the global CMT catalog. Solid lines represent the results obtained from analyses of real data and dotted lines are those from a simulated data catalog. a \({M}_{w}\) 7.0–9.5, b \({M}_{w}\) 6.5–7.0, c \({M}_{w}\) 6.0–6.5, and d \({M}_{w}\) 5.5–6.0. c = 3 and \({t}_{d}\) = 730 days are used. Arrows indicate the triggering distances (see the text). Note that the ranges of the vertical and horizontal axes are different for (a)–(c). Note that the vertical axis ranges are different for the four panels to have a better resolution
