Calderas volcanoes

Caldera volcanoes are formed by the collapse of a large section of the summit or flank of a volcano, following a very large explosive eruption. These eruptions can be so powerful that they empty the underlying magma chamber, causing the ground to cave in and form a large depression. Some calderas can be tens of kilometers wide!
