Traditionally there are two different structures that can be left behind. Although both structures are a type of hole, there are general size requirements for each. If a smaller volcano suffers a collapse and the hole is less than 1 mile in diameter, it is called a crater. If a larger volcano collapses and the hole is larger than 1 mile in diameter, it is called a caldera.
A Caldera, or crater
yes it is true
it is called a caldera a caldera is formed when a volcano erupts and it it such a big eruption that the volcano has no magma left in its chamber and since there is nothing left to support it, it caved in on itself.
A sinkhole.
it's called a crater.
The name of the hollow landform, found at the top of the volcano is called crater.

A sinkhole.
It is called a volcano, the hole is for the lava to come out.
Such a hole is called a fumarole.
A volcano!
A crater
It is a sink hole if it reaches the surface.
it's called a crater.
The collapses star gets squeezed by collapses gas and turns into a black hole.
Calderas form during massive explosve volcanic eruptions. In such eruptions so much material is expelled that it leaves a large empty space under the volcano. The volcano then collapses into this space, forming a giant crater.
