Earthquake! mb 5.0 GREECE https://t.co/1h8d9qIoUQ— Earthquake Report (@ShakingEarth) 2 января 2018 г.
Greece is located in a seismically active zone, which lies in a boundary area between three tectonic plates: the Eurasian, African and Aegean. Earthquakes in the region are caused by movements in the Aegean Sea Plate in a southwesterly direction and the African Plate's subduction beneath the Aegean plate.
