trap-door caldera
GLOSSARY OF VOLCANIC TERMS
A type of caldera formed when one part of the caldera floor subsides to a greater depth than the other side of the caldera floor. In general, trap-door calderas have a partial ring fracture (associated with the side of greatest caldera collapse) and a hinge area (associated with the side of least collapse). Trap-door calderas may represent either calderas that have undergone incomplete collapse, or calderas formed from eruptions from shallow asymmetrical magma chambers (Lipman, 1997: Lipman, 2000, p. 654.
