Histograms of the inter-event times for four groups: a 34.20°N, 134.05°E; b 34.65°N, 136.55°E; c 33.15°N, 132.25°E; and d 33.40°N, 132.80°E. The inter-event time counts are shown in blue, and the fitted mixture distribution is plotted as an orange curve. The red circle and diamond at the top of each panel indicate the estimated \(\mu_{{\text{L}}}\) and \(\mu_{{\text{S}}}\), respectively, with the error bars showing the standard errors on a logarithmic scale
