List of extinct volcanoes

An extinct volcano is a volcano which scientists consider unlikely to erupt again.^[1] A volcano that has not erupted in the past 10,000 years is often listed as extinct.^[2]

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.^[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.
