Dormant volcano

Fumaroles near the summit on Mount Damavand in Iran, which is a sign of a dormant volcano.

Dormant volcanos are the volcanos that are quiet but might erupt again in the future.^[1] If a volcano that has been silent for years erupts again or shows activity, it is called a "dormant volcano". Vesuvius of Italy is a prime example. After many years of dormancy, it re-emerged in 1931. Then it is dormant again. For example, Krakatoa in Indonesia, Aconcagua in Argentina, and Mount Fuji in Japan are dormant volcanoes.
