a Magnitude–frequency distribution of the background seismicity in the 3 years before the mainshock and b corresponding b-values considering different magnitude thresholds. The b-value is evaluated based on the events with magnitudes greater than Mc by using the maximum-likelihood technique. The red line represents the best fit of the GR law; open squares represent the cumulative number of observed events as a function of magnitude
