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. 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 Wikipedia:
Kaldera on tuliperäinen tulivuoren romahtamisesta syntynyt muodostuma, joka voi olla täynnä vettä, jolloin se muodostaa kraaterijärven. Sana tulee espanjan kielen kattilaa tarkoittavasta sanasta 'caldera'.

Example sentence(s):
  • Kaldera syntyy yleensä, kun suuren tulivuoren magmapesäke tyhjenee tulivuorenpurkauksessa. Jos tarpeeksi suuri määrä magmaa purkautuu, tyhjentynyt pesäke ei pysty kannattelemaan yläpuolella olevaa tuliperäistä rakennelmaa. Kammion laitamille syntyy murtumia, yleensä lähes ympyrän muotoon. Nämä rengasmurtumat voivat toimia tuliperäisinä purkautumisteinä. Kun magmapesäke tyhjenee, tulivuoren keskus rengasmurtumien sisällä romahtaa. Romahtaminen voi tapahtua yhden suuren purkauksen seurauksena tai asteittain useiden purkauksien tuloksena. - Wikipedia  
  • Tutkijoita huolettava Calderan kohoaminen hidastui Yellowstonessa --Kaldera on tulivuoren purkauksesta syntynyt kattilaa muistuttava muodostelma. Yellowstonen kaldera on yksi maailman seitsemästä supertulivuoresta. Se purkautui ensi kerran kaksi miljoonaa vuotta sitten. - Breathing Earth
