Calderas and supervolcanic eruptions

[Troodontid]

A possible feature that could be interesting and fit well with ash-producing eruptions is for there to occasionally be a larger-than-normal explosive eruption that causes most of the volcano to collapse to form a large caldera, with a new volcanic mountain forming slowly in the center of the caldera over time. This collapse could be accompanied by pyroclastic flows and volcanic bombs.

Additionally, very rare supervolcanic eruptions could be an interesting event. These events would not form a mountain like all of the other volcano types. Instead, they would start with a single explosive eruption producing a column of ash and heavy ashfall over the surrounding region. This would then be followed fairly quickly by a chain of additional eruptions until they all merge to form a giant ring, with the terrain inside the ring collapsing to form a large flat-bottomed caldera. This collapse would trigger a large pyroclastic flow to radiate outwards in every direction for up to 100-200 blocks, leaving very thick layers of ash behind.

I'm currently in the process of porting to 1.16.x, but I will definitely put this on the list. Sounds pretty cool!
