What the record shows for Czechia
Over the last 20 years, USGS has catalogued 134 earthquakes of magnitude 4 or greater within 300 km of Czechia - roughly 7 a year. That rate describes how often the ground moves enough to be recorded, not how often damage occurs; most of these are never felt.
No tsunamis are recorded within 300 km of Czechia in the NOAA NCEI database. A quiet record is not the same as no exposure - a large enough offshore earthquake can reach coastlines that have never been hit in the historical period.
