WHAT IS CALDERA? A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. The ejection of large volumes of magma in a short time can upset the integrity of a magma chamber's structure by in effect removing much of the chamber's filling material. #jayography #caldera #geography #maps #educationalcontent | Jayography
