The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
caldera
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.
Caldera.
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.
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.
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.

cavern Answer #2: A sinkhole.cavern
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.
No, Central Park is not a volcano. It is a large public park located in the center of Manhattan, New York City. It was not formed by volcanic activity.
