Caldera volcano facts. During a volcanic eruption magma present in the magma chamber underneath the volcano is expelled often forcefully. The caldera was formed when the magma underneath a volcano drained away. Yellowstone Caldera enormous crater in the western-central portion of Yellowstone National Park northwestern Wyoming that was formed by a cataclysmic volcanic eruption some 640000 years ago.

Learn about the volcanic collapse of Mount Mazama and Crater Lake caldera formation in Cascade Range Crater Lake is located within a huge volcanic caldera in the Cascade Range of southwestern Oregon. Depending on their intensity and duration volcanic eruptions can create calderas as much as. A caldera is a volcanic feature formed by the collapse of land surface after a gigantic volcanic eruption.
In such an eruption the volcanos magma chamber is empty enough for the ground above it to drop. It is also referred to as the Yellowstone Supervolcano which refers to its capability of producing an extremely violent volcanic eruption. Without any structural support below the land around the erupting volcanic vent or vents collapses inwardly creating the bowl-shaped caldera.
Yellowstone Caldera is a crater that is approximately 34 miles by 45 miles in size. A caldera may look like a volcanic crater except that a crater is made by blasting outward not by collapsing inward. The Toba Caldera in Sumatra Indonesia is an example of a resurgent caldera.
Formed by a massive volcanic eruption about 74000 years ago the caldera is about 100 kilometers long 29 kilometers wide and 508 meters deep. Urji volcano was subsequently constructed in the center of Corbetti caldera which also contains young lava flows. The subsequent Skaros caldera was created about 70000 years ago and the Cape Riva caldera about 21000 years ago.
