How the Greek Islands Formed: Tectonics and Volcanoes

The Greek islands formed through tectonics and volcanism in the Aegean, not as one single event. This video explains the forces that built the island chains and why places like Santorini look volcanic while others do not. You’ll see how plates, uplift, and eruptions shaped the Aegean, and how that geology still shows up in calderas, cliffs, and hot springs. It is an earth-science overview tied to the map, not a beach guide.
