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)

caldera
Definition from
Wikipedia:
kraterliknande formation som skapas då en vulkan kollapsar, kallas ibland felaktigt för krater. När magmakammaren under en vulkan töms kan "taket" sjunka in och skapa en stor rund struktur som liknar en kittel. [caldera betyder "kittel" på spanska].<br /><br />Till skillnad från kratrar, som ofta bildas av explosioner och/eller vulkanrör, är en caldera ofta mer än 1 km i diameter.
Example sentences:
Kända calderor är Ngorongoro i Tanzania, Crater Lake i USA, Santorini i Egeiska havet och Deception Island i Antarktis. (Wikipedia)
