❓ why
Why do some volcanoes collapse into calderas after huge eruptions?
Quick Answer
When a large magma chamber is partly emptied, the ground above it can no longer be supported. The summit then collapses inward, forming a caldera.
The Full Story
A caldera is a large depression formed when a volcano's magma chamber is drained during a major eruption or emptied by slow magma withdrawal. With less support below, the summit area sinks or collapses into the void. This process can create a much larger feature than a simple crater. Yellowstone in the United States and Toba in Indonesia are famous examples of huge caldera systems formed by massive eruptions and collapse.
