Krater-Formation Theory

The Krater-Formation Theory explains how large volcanic craters, called calderas, form when a volcanic eruption empties a magma chamber beneath the surface. As the magma is released, the support for the land above weakens, causing the ground to collapse inward. This collapse creates a large, often circular, depression known as a caldera. The process involves intense volcanic activity, significant magma withdrawal, and subsequent structural settling. Essentially, it's a natural outcome of massive eruptions that evacuate underground magma, resulting in the vast, crater-like depressions seen at certain volcanoes around the world.
