Adriatic plate

[1] The fault zone that separates the two is the Periadriatic Seam that runs through the Alps.

Oceanic crust of the African plate is also subducting under the Adriatic/Apulian plate off the western and southern coasts of the Italian Peninsula, creating a berm of assorted debris which rises from the seafloor and continues onshore.

This subduction is also responsible for the volcanic interactions of southern Italy.

The Adriatic Sea, Istria, the eastern Italian Peninsula, Malta, and the coastal part of Slovenia are on the Adriatic/Apulian Plate.

Mesozoic sedimentary rocks deposited on the plate include the limestones that form the Southern Calcareous Alps.
