Plate tectonics extensional

In Fig. 7, in three separated maps, all thrust (in red), strike-slip (in green), and extensional (in blue) focal mechanisms are shown these views help to study at larger scale the active tectonic styles. Thrust beach balls represent the compressive tectonic style and their distribution shows where the boundary between tectonic plates collides. This type of deformation occurs along a nearly continuous and narrow zone in Northern Africa, from Morocco to Northern Sicily, with two interruptions at the Gibraltar Strait (Fig. 6c) and south of Sardinia. Another continuous part of the tectonic boundary characterized by compressive features is along the eastern part of the Adriatic Sea, along Dinarides and Hellenides belts and partially around the Hellenic Trench. Other minor regions characterized by a compressive deformation are in the Northern Apeimines and around Cyprus Island.
