Fig. 4: The cumulative number of events for the magnitude of the earthquake.

The plotted lines are curves for estimating the b-value shown in Fig. 3c. Each line corresponds to the curve for each r and θ range on the Mohr circle, as shown in the legend. The magnitude range for the estimation, which is shown by the unshaded area, is from Mc = –0.3 to M = 2. Lines with solid circles show a frequency–magnitude curve taking minimum b-value (i.e., θ = 70–90, r = 0.8–1).
