What is it in Santorini?

It is the bay bounded by the various volcanic islands of the Santorini archipelago.

How is it formed?

The calderas appear with the subsidence of the central part of the volcanoes, in particular because of the collapse of the magma chambers which empty during the eruptions.

To clarify, you will find this complete definition extracted from Wikipedia: “A caldera is a vast circular or elliptical depression, generally of a kilometer order, often with a flat bottom, located in the heart of certain large volcanic buildings and resulting from an eruption which empties the underlying magma chamber. “
