The oldest volcano is probably Etna and that is about 350,000 years old. Most of the active volcanoes that we know about seem to be less than 100,000 years old. Volcanoes grow because lava or ash accumulates on the volcano, adding layers and height.
What is the most extinct volcano?

How old is the youngest volcano?
Eruptions as recently as about 50,000 years ago produced Koko Crater, one of the youngest of the features known as the Honolulu Volcanics. Diamond Head, another of the Honolulu Volcanics, is about 0.4-0.5 million years old. On Kaua`i, the main volcanic episode ended about 4 million years ago.
Can a dead volcano erupt?

Do volcanoes die?
Volcanoes go dormant because magma from the Earth’s mantle can no longer reach the volcano. For example, in Hawaii, the line of islands are slowly moving to the northwest. Meanwhile, the supply of magma stays in the same place within the Earth, which currently happens to lie beneath the Big Island.
