Extinct volcanoes are those that scientists consider unlikely to erupt again because the volcano no longer has a magma supply. Examples of extinct volcanoes are many volcanoes on the [[Hawaiian–Emperor seamount chain]] in the Pacific Ocean (although some volcanoes at the eastern end of the chain are active), [[Hohentwiel]] in [[Germany]], [[Shiprock]] in [[New Mexico]], [[United States|U.S.]], [[Capulin Volcano National Monument|Capulin]] in New Mexico, U.S, [[Zuidwal volcano]] in the [[Netherlands]], and many volcanoes in [[Italy]] such as [[Monte Vulture]]. [[Edinburgh Castle]] in Scotland is located atop an extinct volcano, which forms [[Castle Rock (Edinburgh)|Castle Rock]]. Whether a volcano is truly extinct is often difficult to determine. Since "supervolcano" [[caldera]]s can have eruptive lifespans sometimes measured in millions of years, a caldera that has not produced an eruption in tens of thousands of years may be considered dormant instead of extinct. An individual volcano in a monogenetic volcanic field can be extinct, but that does not mean a completely new volcano might not erupt close by with little or no warning, as its field may have an active magma supply.
