Seismic activity and Gutenberg–Richter law. (a) Magnitude ML density per year. Grey line represents the magnitude bin with the maximum number of events for each year. Black line represents the magnitude bin with the KDE (Kernel Density Estimation) maximum number of events for each year. The red box indicates the period and data used to constrain the Gutenberg–Richter law on (b). (b) Gutenberg–Richter law for the period 2010–2019 (red line). The Weichert algorithm is used with a completeness magnitude of ML 1.8 (dotted vertical grey line). Black circles and red circles represent annual non-cumulative and annual cumulative number of earthquakes per magnitude bin, respectively.
