This is known as a Caldera.
Caldera
This is a crater
It is called a caldera. It is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption, such as the one at Yellowstone National Park in the US. They are sometimes confused with volcanic craters.(wikipedia). Hope that helped :-D
The hole that is formed by the eruption or collapse of the central vent of a volcano is called a caldera. A caldera is typically much larger in size compared to the original volcanic crater and can be several kilometers in diameter.
Most craters are formed by the impacts of asteroids and comets. Some craters on volcanically active bodies are volcanic in origin.
No. A caldera is a volcanic structure. It is formed by the collapse of a volcao rather than a magma body.
It was formed by the collapse of the volcano Mount Mazama.
Volcanic crater.
This is a crater
This is known as a caldera or a crater.
The large volcanic depression occupied by Crater Lake, Oregon is a
Crater Lake formed after the collapse of Mount Mazama.
Caldera collapse followed major ash and pyroclastic-flow eruptions 6000 years ago.
The island in Crater, called Wizard Island was formed by small volcanic eruptions that occurred after the Crater Lake caldera formed but before the volcano went extinct.
Crater, Caldara and Lava plateau
This may be a volcanic vent, crater or caldera depending on the specific volcanic event that formed the hole!
