The rare phenomenon you're talking about is called a calderas.
Caldera is the term given to large depressions associated with volcanoes that form when volcanoes explode or collapse into the earth.
If you're looking for what this is the definition of, then your question described a caldera.
The depression associated with a volcano is called a caldera.
This is known as a caldera.
That would be a "caldera".
This is a crater
A circular depression that forms when a magma chamber empties is called a caldera. It is a large volcanic crater made from the collapse of a volcano's mouth.
A summit crater is a circular depression in the ground caused by volcanic activity.
A volcanic crater is a generally circular shaped depression.
A caldera is a depression formed by an extremely large, explosive volcanic eruption. The largest eruptions drain huge amounts of magma from underground, causing the ground above to collapse into the space left behind.
Volcanic crater.
This is a crater
This is known as a caldera or a crater.
No. A crater is a circular depression in the ground formed by an impact or explosion. A volcano bomb is a blob of lava hurled out during a volcanic eruption.
A circular depression that forms when a magma chamber empties is called a caldera. It is a large volcanic crater made from the collapse of a volcano's mouth.
A volcanic crater is a circular depression caused by volcanic activity.
Dallol is a volcanic explosion crater in the Danakil Depression in Ethiopia.
A summit crater is a circular depression in the ground caused by volcanic activity.
A volcanic explosion is an eruption.
A volcanic crater is a generally circular shaped depression.
You spelled volcanic explosion correctly in the question, though volcanic eruption might be preferred.
A caldera is a depression formed by an extremely large, explosive volcanic eruption. The largest eruptions drain huge amounts of magma from underground, causing the ground above to collapse into the space left behind.
