The approximate location of the 8 September 2013 Hațeg Earthquake. Google Maps.
The Carpathian Mountains form part of the suture formed when the Tethys Ocean closed during the Mesozoic, joining the continents of Laurasia (to the north) and Gondwana (to the south). The area is now internal to the Eurasian continent, but the area to the south, known as the Moesian Platform, has a separate origin to the rest of Europe. This system is once again being stressed by the impact of Africa into Eurasia from the south, with the Anatolian Plate (which underlies Anatolian Turkey), Aegean Plate (which underlies southern Greece) and Adriatic Plate (which underlies eastern Italy and the western Balkan Peninsula) caught between the two larger units, leading to a more complex interplay of stresses across southeastern Europe. The Antatolian and Aegean Plates are located to the south of the Moesian Platform, and are being pushed to the west, while the Adriatic Plate lies to the west of the Aegean Plate and Moesian Platform, and is being pushed to the northeast.
