Mount Vesuvius is 1281 meters above sea level. Vesuvius is approximately 17,000 years old. Vesuvius is active, but it hasn't erupted since 1944. Mt. Vesuvius is on the coast of the Bay of Naples. It is the most densely populated volcanic region in the world, it has about 3000 people living in close vicinity of it. It has erupted about 50 times since 79 A.D., Pompeii wasn't the only city that got buried from Vesuvius's tragic explosion in 79ad. Herculaneum, Pompeii, Stabiae, and other cities got covered in ash. Mount Vesuvius was created when the African and Eurasian plate collided. The boundary between these two plates is called a destructive boundary, which is when one plate slides under another one. The African plate slid under the Eurasian plate, because the African plate was denser.The base is 48 kilometers (30 miles).
