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.

It is difficult to distinguish an extinct volcano from a dormant (inactive) one. Volcanoes are often considered to be extinct if there are no written records of its activity. Nevertheless, volcanoes may remain dormant for a long period of time. For example, Yellowstone has a repose/recharge period of around 700 ka, and Toba of around 380 ka. Vesuvius was described by Roman writers as having been covered with gardens and vineyards before its famous eruption of AD 79, which destroyed the towns of Herculaneum and Pompeii. Before its catastrophic eruption of 1991, Pinatubo was an inconspicuous volcano, unknown to most people in the surrounding areas. Two other examples are the long-dormant Soufrière Hills volcano on the island of Montserrat, thought to be extinct before activity resumed in 1995 and Fourpeaked Mountain in Alaska, which, before its September 2006 eruption, had not erupted since before 8000 BC and had long been thought to be extinct.
