Seismicity Background

Most shallow earthquakes in central and northern Greece (depths less than 50 km) result from interaction between the Eurasia plate and the small Aegean Sea plate, which is moving southwest with respect to the Eurasia plate with a velocity of about 30 mm/year.
Shallow-focus earthquakes also occur in the volcanic arc that is associated with the subduction of the Africa plate beneath the Aegean Sea plate, in the Dodecanese and Cyclades Islands, over 100 km north of Crete.
Intermediate-depth earthquakes (depths greater than 50 km) occur within the subducting Africa plate beneath central Greece and the Dodecanese and Cyclades Islands.
A belt of shallow-focus seismicity along the western coast of Greece to the north of Lefkada, and extending north along the Adriatic coast of the Balkan Peninsula, is characterized by reverse fault earthquakes occurring in response to northeast-southwest crustal convergence.


The Geodynamic Institute (G.I.) is one of the four Institutes comprising the National Observatory of Athens (N.O.A.)
In 1893, the Greek Seismological Survey was formed
In 1897 the first seismograph installed in Athens and in 1899 the first seismic network started to operate.
Twenty two (22) permanent seismic stations, covering the whole country, are today in operation by the G.I.
Attention has been also given to observe micro earthquakes, which give useful information about the seismicity within a short period of time.
