Аnnotation: The peculiarities of the seismic activations (SA) in Italy, Greece and Turkey for the 17th – 19th centuries are analyzed to clarify the general patterns of SA occurrence in separate seismically active regions associated with similar geodynamic conditions. The strong earthquakes (М ≥5.6, I ≥IX) clustering in time in Italy, Greece and Turkey in the 17th – 19th centuries allowed us to identify a number of SAs of various durations both in each country as well in the whole region. However, the revealed periodicity is extremely uneven in the time range, the number of earthquakes, and the intervals between the individual SAs. 12 SAs were identified in Italy, the maximum seismic activity was observed in17th and 18th centuries while there was its gradual decline towards the 19th century.9 and 8 SAs were observed in Greece and Turkey, respectively, whereas seismic activity in these countries strongly increased in the 19th century. It is possible to outline some periods of general seismic activation for the entire region: 1658–1680, 1694–1743, 1766–1791, 1846–1867.
