The Periadriatic Seam (or fault) is a distinct geologic fault in Southern Europe, running S-shaped about 1,000Â km (621Â mi) from the Tyrrhenian Sea through the whole Southern Alps as far as Hungary. It forms the division between the Adriatic plate and the Eurasian plate.

đ Periadriatic Seam in the context of Apulian Plate
The Adriatic or Apulian plate is a small tectonic plate carrying primarily continental crust that broke away from the African plate along a large transform fault in the Cretaceous period. The name Adriatic plate is usually used when referring to the northern part of the plate. This part of the plate was deformed during the Alpine orogeny, when the Adriatic/Apulian plate collided with the Eurasian plate.
The Adriatic/Apulian plate is thought to still move independently of the Eurasian plate in NNE direction with a small component of counter-clockwise rotation. The fault zone that separates the two is the Periadriatic Seam that runs through the Alps. Studies indicate that in addition to deforming, the Eurasian continental crust has actually subducted to some extent below the Adriatic/Apulian plate, an unusual circumstance in plate tectonics. 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.

Periadriatic Seam in the context of Karawanks
The Karawanks or Karavankas or Karavanks (Slovene: Karavanke; German: Karawanken, German pronunciation: [kaĘaËvaĹkĹĚ] ) are a mountain range of the Southern Limestone Alps on the border between Slovenia to the south and Austria to the north. With a total length of 120 kilometres (75Â mi) in an eastâwest direction, the Karawanks chain is one of the longest ranges in Europe. It is traversed by important trade routes and has a great tourist significance. Geographically and geologically, it is divided into the higher Western Karawanks and the lower-lying Eastern Karawanks. It is traversed by the Periadriatic Seam, separating the Apulian tectonic plate from the Eurasian Plate.
Near the summit of the Dreiländereck (1,508 m) is the tripoint of the three countries: Austria, Italy and Slovenia.
Periadriatic Seam in the context of Southern Alps (geology)
The Southern Alps are a geological subdivision of Alps that are found south of the Periadriatic Seam, a major geological faultzone across the Alps. The southern Alps contain almost the same area as the Southern Limestone Alps. The rocks of the southern Alps gradually go over in the Dinarides or Dinaric Alps to the south-east. In the south-west they disappear below recent sediments of the Po basin that are lying discordant on top of them.
