A large opening formed by a collapsed volcano is known as a caldera. This geological feature occurs when a volcano erupts and expels a significant amount of magma, leading to the collapse of the ground above the emptied magma chamber. Calderas can vary in size and may eventually fill with water, creating lakes, or be surrounded by new volcanic activity. Notable examples include the Yellowstone Caldera in the United States and the Santorini Caldera in Greece.
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.
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.
A caldera is a large opening caused by the collapse of the top of a volcano following a massive eruption. It can be several kilometers wide and typically forms when the magma chamber underneath the volcano is emptied during an eruption, leading to the collapse of the overlying land.

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

The large hole at the top of a volcano is called a "crater." It is formed when explosions or collapses create a depression at the summit of the volcano.
Crater Lake in Oregon was formed approximately 7,700 years ago following the collapse of Mount Mazama during a massive volcanic eruption. The volcanic caldera left behind was gradually filled with rain and snowmelt, forming the stunning lake we see today.

No. A shield volcano is a large volcano with broad, shallow slopes formed from layers of lava flows formed by non-explosive eruptions. A cinder cone volcano is a small, steep-sloped volcano composed of pieces of rock formed by lava that was ejected explosively into the air.
