Whose work first explained why volcanoes can collapse into calderas after eruptions?
Quick Answer
Caldera formation was explained through geologic studies of large explosive eruptions and magma-chamber emptying. Scientists recognized that when support is removed, the summit can collapse into a large basin.
The Full Story
Volcano calderas were understood gradually through studies of huge eruptions and collapse structures. Scientists realized that after large volumes of magma are ejected or withdrawn, the roof of the magma chamber may fail and sink. This can create a broad, steep-walled depression much larger than a normal crater. Famous examples include Krakatau and Yellowstone. Caldera research helped distinguish between small summit craters and massive volcanic collapse features.
