Volcanoes grow because lava or ash accumulates on the volcano, adding layers and height..
Is Vesuvius extinct?
Although in a dormant phase at present, Vesuvius is an extremely active volcano and particular for its unusually varied style of activity: it ranges from Hawaiian-style emission of very liquid lava, extreme lava fountains, lava lakes and lava flows, over Strombolian and Vulcanian eruptions to violently explosive, …
What is an old volcano called?

What is the oldest extinct volcano?
Etna in Italy is sometimes called the oldest active volcano because it has the longest historic record of eruptions. It has erupted 190 times in the last 3,500 years. This is a bit misleading, however, because it was already an old volcano when the first recorded eruption occurred in 1,500 BC.

What volcano can destroy the world?
How does a ‘supervolcano’ eruption work? Below Yellowstone National Park, there’s a huge magma reservoir that’s responsible for all the geysers and hot basins, bubbling away — and it’s precisely this reservoir that has the potential to destroy humanity.
Did anyone survive in Pompeii?
That’s because between 15,000 and 20,000 people lived in Pompeii and Herculaneum, and the majority of them survived Vesuvius’ catastrophic eruption. One of the survivors, a man named Cornelius Fuscus later died in what the Romans called Asia (what is now Romania) on a military campaign.
