List of extinct volcanoes

An extinct volcano is a volcano which scientists consider unlikely to erupt again.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. A volcano that has not erupted in the past 10,000 years is often listed as extinct.Ball, Jessica.  "Voices: Dead or alive ... or neither? Why a dormant volcano is not a dead one," Earth Magazine (American Geosciences Institute). September 8, 2010; retrieved 2012-6-14.

The extinct volcano no longer has a magma supply.  An extinct volcano is no longer near an active geologic hot spot, if it ever was.Monterey Bay Aquarium Research Institute,  "Life-cycle of Hawaiian hot spot volcanoes" ; retrieved 2012-6-14.

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.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.  Dormant volcanoes may still erupt, whereas extinct ones cannot.
