We have analysed more than 1800 records of very weak microearthquakes registered in the NE part of the Bohemian Massif during the 1998-2008. Cross-correlation analysis showed that 74% of these events are duplets and multiplets or near-multiplets. 191 families of these similar events were distinguished, representing small-volume repeatedly activated focal domains. The families are largely variable in terms of number of events, overall durations of activity and time distributions of the events.
