Definition from
CENGAGE Learning:
A vast depression at the top of a volcanic cone, formed when an eruption substantially empties the reservoir of magma beneath the cone's summit. Eventually the summit collapses inward, creating a caldera. A caldera may be more than 15 kilometers in diameter and more than 1000 meters deep.
Example sentences:
Subsequent eruptions from the Long Valley magma chamber were confined within the caldera with extrusions of relatively hot (crystal-free) rhyolite 700,000 to 600,000 years ago as the caldera floor was upwarped to form the resurgent dome followed by extrusions of cooler, crystal-rich moat rhyolite at 200,000-year intervals (500,000, 300,000, and 100,000 years ago) in clockwise succession around the resurgent dome. (USGS)
Calderas tend to form after a series of large eruptions. Usually a new volcano starts to grow inside, eventually covering it. (About.com: Geology)
Over the course of several hundred years following the creation of the caldera, rain and snow filled the basin to a depth of 1,943 feet (592 meters). Crater Lake today is the nation’s deepest lake. (Crater lake)

Definition from
GeoWiki:
Кальдера (Исп. caldera - "большой котел") - крупная вулканическая форма рельефа, образующаяся при взрыве, провале, или оседании большой территории вокруг эруптивного центра во время или сразу после вулканического извержения. Обычно имеет круглую форму и имеет крутые стенки. От кратера вулкана отличается гораздо большими размерами.
Example sentences:
Кальдеры часто заняты озерами. (Географический слова�)
По преобладающему механизму формирования выделяют кальдеры проседания и взрывные кальдеры. (GeoWiki)
Кальдера Узон - это уникальный в масштабе Земли район проявления современного вулканизма. (Туристическая кампан�)
