Additional info:
The earthquake was widely felt by people near the epicentre and some reports are also from southern Bohemia (Tábor, Volyně, Milevsko, Kovářov). The maximum reported intensity reached VI on the EMS-98 macroseismic scale. If you felt it too you can report your experience here. It is the strongest earthquake of a seismic swarm which started in the Nový Kostel area on 23.5.2014 and continued after a few relatively quiet days by another series of felt earthquakes. Seismic swarms occur repeatedly here. No greater damage is expected by this type of earthquakes. This earthquake is the strongest from this region since 1985 when an earthquake with magnitude 4,8 was recorded.
It presented no threat to any of the Czech NPPs.
