Figure 4.
Time versus magnitude distribution of earthquakes (black dots) occurred within the analysis regions from 1960 to 2023 (|$z \le 50$| km) according to the HORUS catalogue (Lolli et al. 2020) and used for the models’ calibration, testing and optimization. The red line represents the magnitude of completeness estimated using the maximum curvature method (Wiemer & Wyss 2000).
