Frequency–magnitude distribution for the year 2011 swarm in western Bohemia. Bold solid lines refer to the cumulative distribution, whereas boxes refer to the number of events in each magnitude bin for the cases of the complete data set (light gray), the events in periods with estimated Mc≥1.5 (dark gray), and in periods with estimated Mc≤0.5 (black). For comparison, the two dashed lines refer to Gutenberg–Richter relations with b=1.22 and ±1 standard deviation (thin solid lines).
