Caldera Volcano

1. These are the most explosive of the earth’s volcanoes.

2. They are usually so explosive that when they erupt they tend to collapse on themselves rather than building any tall structure. The collapsed depressions are called calderas.

3. Their explosiveness indicates that its magma chamber is large and in close vicinity.

4. A caldera differs from a crater in such a way that a caldera is a huge depression caused by a collapse after a large-scale eruption, whereas a crater is a small, steep side, volcanic depression bored out by an eruptive plume.
