caldera
Let an agent explain calderas, relay formation, types, examples and monitoring from volcanology sources, route volcanic hazard preparedness, correct sensational supervolcano claims with attribution, and distinguish calderas from volcanic craters, maars, impact craters and sinkholes.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain calderas, relay formation, types, examples and monitoring from volcanology sources, route volcanic hazard preparedness, correct sensational supervolcano claims with attribution, and distinguish calderas from volcanic craters, maars, impact craters and sinkholes.
A large volcanic depression formed when a magma chamber empties, often in a major eruption, and the ground above collapses into it, producing a basin much wider than a typical volcanic crater, sometimes filling with water to form a caldera lake, as at Crater Lake, or hosting resurgent activity as at Yellowstone; calderas can be tens of kilometres across and their forming eruptions can be extremely large. Active caldera systems are monitored for unrest, and the public should follow official volcano warnings, while sensational claims about supervolcanoes should be checked against scientific assessments.
What it is for: A collapse depression from emptied magma chambers.
It can be explain formation and types; relay examples and monitoring; route volcanic hazards; correct sensational claims.
Distinguishing features
Collapse depression
Wider than craters
Large forming eruptions
Lakes and resurgence
What it looks like
A large basin or ring depression, sometimes with a lake or central resurgent dome.
Physical character
size: up to tens of kilometres across note
Crater Lake: caldera lake in Oregon note
registry parents: depression, volcanic landform note
How it is recognised
Large volcanic collapse depression
Caldera, volcanic caldera
Volcanic craters are small vents; maars are explosion craters; impact craters come from meteorites; sinkholes form by ground collapse without volcanism
