Aegean Sea Plate

The Aegean Sea Plate is a small but highly active microplate caught in the complex collision zone between Africa, Eurasia, and Anatolia. This region experiences back-arc extension as the African Plate subducts beneath it, creating the volcanic arc of the South Aegean. The result is a landscape dotted with active volcanoes like Santorini, frequent earthquakes, and the beautiful but geologically young Greek islands, all shaped by ongoing tectonic forces.
