Fig. 4From: Forecasting tectonic tremor activity using a renewal process modelKolmogorov–Smirnov test for two groups: a 34.20°N, 134.05°E and b 33.10°N, 132.20°E. The black line shows the relationship between the event number and the original event time normalized to the event number. The blue line shows the relationship between the transformed time and the event number. The gray zone indicates the region where the null hypothesis is rejected at the 95% level. The blue line outside of this zone is marked by red dotsBack to article page
