English term or phrase: caldera
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 sentence(s):
  • 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

カルデラ
Definition:
カルデラとは,ポルトガル語で「大鍋」の意味を持ち,火山に見られる巨大な凹みである.巨大とは概ね直径2km以上のものを指す.隕石が衝突してできたクレーターとは明瞭に区別される.地下からマグマが一斉に噴出することで,地表が陥没するものを「陥没カルデラ」と呼ぶ.巨大噴火でできるカルデラは,陥没カルデラであることが多い.言い換えれば,カルデラの存在は,火山が過去に巨大噴火を起こしたことの証明である.
