Fig. 2From: The 2022 Mw6.2 Pasaman, Indonesia, earthquake sequence and its implication of seismic hazard in central-west Sumatraa 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 magnitudeBack to article page
