How long is it before a volcano is extinct?
An extinct volcano must have not erupted in historical times (when history was first recorded). It takes many many years to distinguish an extinct volcano from a dormant one, and it is very difficult too. An example would be the Fourpeaked Mountain in Alaska, which prior to September 2006, is not believed to have erupted since earlier than 7994 BC! Mostly, it takes about 5,000 to 6,000 years for a dormant volcano to be considered extinct, except in rare cases. Another would be the hotspot theory. Whenever a volcano island moves away from the hotspot, the magma source is cut off, and the volcano is considered extinct. An example would the Hawaii Chain Islands.
