Caldera structure is similar on all of these planetary bodies, though the size varies considerably. The average caldera diameter on Venus is 68 km (42 mi). The average caldera diameter on Io is close to 40 km (25 mi), and the mode is 6 km (3.7 mi); Tvashtar Paterae is likely the largest caldera with a diameter of 290 km (180 mi).
A topographic map of Ngorongoro Crater in northern Tanzania, the world's largest inactive, intact, and unfilled volcanic caldera, which formed when an immense volcano erupted and collapsed on itself 2–3 million years ago. The floor of the caldera is 600 metres (2,000 ft) below its rim and covers more than 260 square kilometres (100 sq mi).
Caldera – Cauldron-like volcanic feature formed by the emptying of a magma chamber; Cinder cone – Steep hill of pyroclastic fragments around a volcanic vent; Complex volcano – Landform of more than one related volcanic centre; Cryptodome – Roughly circular protrusion from slowly extruded viscous volcanic lava
Kaldereta or caldereta [1] [2] is a goat meat [3] stew from the Philippines.Variations of the dish use beef, [4] chicken, [5] or pork. Commonly, the goat meat is stewed with vegetables and liver paste.
The Misema Caldera is in the order of 3,500 to 4,000 km 2 (1,400 to 1,500 sq mi), making the complex similar to the Yellowstone Caldera in Wyoming, Lake Toba in Indonesia and strikingly similar in structure to the Olympus Mons caldera on Mars. [2] As a result, the Blake River Group is best categorized as a meganested caldera complex. [3]
Calderas that were active in the Archean eon (before approximately 2500 million years ago) in Precambrian time. Note that virtually no mountain belts of any notable topographical relief survive from this eon, so all surviving volcanic remnants are embedded in mostly-flat continental cratons, such as in greenstone belts or very large well-preserved supervolcanoes

Volcanic calderas that are partially or fully submerged under the water of a larger ocean or lake, sometimes forming a reef, bay or harbor.. Not to be confused with atolls, where a sunken seamount has grown a ring of coral islands surrounding a lagoon.
