Temporal evolution of the Kagan information score difference between the ETAS31 and the STEP39 models. Green dots represent days with positive score difference (ETAS > STEP), while red dots indicate the opposite. Panel (a) Absolute Kagan information score differences. The vertical lines represents the occurrence time of observed M + 3.95 earthquakes. Panel (b) Cumulative Kagan information score differences. The histogram represents the daily number of observed M + 3.95 earthquakes. Frequencies are reported on the y-axis on the right side.
