Caldera.
yes, I think so. because, very large volume of magma is ejected and then magma chamber can't support the volcano above it. then the volcano begins to sink into the earth.magma chamber empties and a new collapsed depression occurs.
The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
Caldera
No. The largest volcano in Hawaii is Mauna Loa. Caldera is not the name of any particular volcano, but a term used to describe a volcano that has collapsed after an extremely large eruption.
a crater
a vent i think
Crater Lake formed after Mount Mazama, a volcano, collapsed during a cataclysmic eruption.

If you are talking about the large crater created after a volcano errupts, then it would be a caldera. They are formed after the magma chamber is emptied, when the cone of the volcano collapses to fill the empty space.
The large Kiama blowhole was formed by a dyke in the rock, it was eroded by wave action, the rock then collapsed, and the tunnel formed
A caldera is simply a volcanic cauldron. A large circular hole that marks the position where the rocks of the volcano have collapsed into the emptied magma chamber below
