Quizplus · Accepted Answer

Calderas are large, basin-like depressions that form following the evacuation of a magma chamber/reservoir. When a volcano erupts, it can empty the chamber beneath it. The ground surface then collapses downward into the emptied or partially emptied magma chamber, leaving a large, circular depression.
