What is under Santorini that makes it so dangerous? (it's not just earthquakes)

New earthquake video here: https://www.youtube.com/watch?v=YWh8_k7qKRU Santorini has been experiencing many earthquakes, resulting in evacuations...but the earthquakes aren't the only possible issue in Santorini. Santorini has a destructive volcanic history and has lots in common with "ring of fire" volcanoes elsewhere on Earth. This video shows what's under Santorini to produce its volcanic behavior. Parts of the Mediterranean are actually just as dynamic as the Pacific Ring of Fire, even though we don't always think of them that way!
