Latest quakes in Greece: Greece has a lot of earthquake activity, but most of them occur around the margin of the Aegean microplate. The Cycladic islands are located in its center and therefore seismically comparably quiet.
Top 20 quakes in 2016: Several magnitude 7 quakes occurred in 2016 (but none above M8): Papua New Guinea, NZ, Ecuador, Solomon Islands, Sumatra, Chile, Alaska and others - nearly all major earthquakes were located near active subduction zones.
