List of extinct volcanoes includes volcanoes which scientists consider unlikely to erupt again.[1] A volcano which has not erupted in the past 10,000 years is often listed as extinct.[2]
The extinct volcano no longer has a lava supply. An extinct volcano is no longer near an active geologichot spot, if it ever was.[3]
Volcanologists sometimes can't tell whether a volcano is extinct or dormant. A caldera that has not produced an eruption in tens of thousands of years is likely to be considered inactive.[4] Dormant volcanoes may still erupt, whereas extinct ones cannot.
Edinburgh Castle in Scotland is located on a dolerite plug, the remnant of a volcano that went extinct many millions of years ago. [11]
↑The plural of volcano can be either volcanos or volcanoes. Both are equally correct, and it is not a matter of British vs US spelling. Oxford English Dictionary. Spelling in any particular Simple page tries to be consistent.
↑Some volcanologists have described to extinct volcanoes as "inactive". However, the term 'inactive' is now more often used for dormant volcanos which were once thought to be extinct.
