Calderas are volcanoes where silicic magmas evolve and then explode, leaving a huge hole. They usually erupt a few times, with reposes lasting from centuries to many millennia. Their eruptions can be as voluminous as thousands of cubic kilometers. The eruptions certainly have global impact.

Calderas erupt only a few times and stay in repose for millenia. The environmental effects of a large caldera event have never been experienced by people who could write down what happened.
