All these swarms occurred in the NovA1/2 Kostel focal zone. Up to 25,000 M (L) a parts per thousand currency sign3.7 events with depths between 6 and 10 km were detected in the 2011 swarm. Utilizing WEBNET data, we analysed the cumulative seismic moment, magnitude-frequency and interevent time distributions, space-time distribution of foci and typical focal mechanisms. For this purpose, we improved the formula for estimating the local magnitude M (L) used by WEBNET. The 2011 swarm exhibited much higher rapidity than the swarms of 2000 and 2008. The magnitude-frequency distributions of all the three swarms are similar, having the b-value close to 1.0. However, the events of higher magnitudes, roughly M (L) similar to 3.0+, depart markedly from the general trend of the weaker events.
