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

ज्वालामुखी कुंड

Definition from CENGAGE Learning:
किसी ज्वालामुखीय शंकु के ऊपर बना एक बड़ा गढ्ढा, जो तब बनता है जब कोई विस्फोट शंकु की चोटी के नीचे के मैग्मा के कुंड को खाली करता है। अंतत: यह चोटी अंदर की ओर धंस जाती है और ज्वालामुखी कुंड बनता है। किसी ज्वालामुखी कुंड का व्यास 15 किमी और उसकी गहराई 1000 मीटर से अधिक हो सकती है।

Example sentence(s):

सबसे नये द्वीप, ईसाबेला और फर्नान्दिना का निर्माण अभी तक चल रहा है, जिसमे अप्रैल 2009 का सबसे हाल का ज्वालामुखी विस्फोट शामिल है जब ज्वालामुखीय द्वीप फर्नान्दिना से लावा द्वीप की तटरेखा और केन्द्रीय ज्वालामुखी कुंड की दिशा में बहने लगा था। - wikipedia
आमतौर पर ज्वालामुखी कुंड बड़े विस्फोटों की एक श्रृंखला के बाद बनते हैं। एक नया ज्वालामुखी अंदर तैयार होना शुरू हो जाता है, जो बाद में इसे ढंक लेता है। - About.com: Geology
