A caldera
When a volcanic cone collapses it forms a caldera.
The large circular depression at the top of a volcano that forms when the roof of the magma chamber collapses is called a caldera. Calderas can be huge in size and are formed during explosive volcanic eruptions or when the magma chamber empties and the summit collapses into the void left behind.

It is a volcanic caldera which is a large, bowl-shaped volcanic depression that forms when the top of a volcanic cone collapses into the space left after magma is ejected during a violent volcanic eruption.

The basin shaped crater at the top of a mountain is called a caldera. It forms when a volcano collapses into itself after an eruption, creating a large, circular depression.
Most volcanoes, when they finish erupting, leave a crater behind when the magma retreats down the volcanic pipe. Occasionally this will fill with water to leave a lake.A large surface explosion will leave behind a Caldera - a broad area possibly still of geothermal activity. Such as Yellowstone, or Okataina.
A volcanic mountain can have a crater at its summit, which may contain a volcanic vent, lava dome, or caldera. The top of a volcanic mountain can also be covered in ash, rock debris, and volcanic gases.

When a volcano collapses into itself at its top, it forms a large crater called a caldera. Calderas are formed when the magma chamber of a volcano empties during an eruption, causing the summit to collapse inward.
A hole at the top of a mountain can be referred to as a summit vent or a volcanic crater, depending on whether it is a natural opening or the result of volcanic activity.
It's Hawaii.
