Mount Vesuvius facts for tourists and hikers

Walking up the spiral path to the crater of Mount Vesuvius may seem like a picnic, but I was glad when it was over.

Call me hysteric, but a hike on the only active volcano in mainland Europe gave me the jitters. After all, Vesuvius has erupted many times and is regarded as one of the most dangerous volcanoes in the world. And even though I know, the danger is not due to the immediate risk of a sudden deadly explosion, but to the density of the population living in nearby Naples; it is still kind of scary.

Especially with these 5 facts in mind:

  1. When Mount Vesuvius erupted in AD 79 burying the Roman cities Pompeii and Herculaneum it spewed 1.5 million tons lava per second. Like shooting out 250 000 fully grown elephants each second and letting them fall through the air.
  2. The eruption released a hundred thousand times the thermal energy released by the Hiroshima bombing. An estimated 16 000 people lost their lives.
  3. Vesuvius has erupted many times since then. On April 7, 1906 it ejected more lava than ever and killed 100 people. The last major eruption in March 1944 destroyed four villages.
  4. Volcanologists have adopted the term “Plinian” from Vesuvius to describe large volcanic eruption clouds. This is due to Pliny the Younger, who described the 79 AD eruption as a tall, “umbrella pine” shaped cloud that rose above the volcano.
  5. Most rocks erupted from Vesuvius are andesite. Andesite lava creates explosive eruptions, which makes Vesuvius especially dangerous and unpredictable.

In spite of this the only activity I saw during my walk along the summit rim was small clouds of dirt or steam forming at the bottom of the crater. And the souvenir geologist collection of pumice, andesite and other volcanic rocks, I’ve got stored away as a somewhere is peacefully dormant under layers of dust.

    Ooh, interesting. A little scary, but even more interesting. Still haven’t convinced my 11-y-o- to go to Pompeii because of Vesuvius, so this walk is probably a lost cause. Something I’ll have to do on my own, it looks. How long a hike is this?

      From the parking lot it’s a couple of hours max including a walk forth and back along three-quarters of the way around the rim of the crater. You can also take a bus from the parking lot to within 200 metres of the summit, so it is not strenuous in any way.

    It is a little sly bastard….

    However, volcanoes are there to remember us that our beloved Earth is alive.

    I can’t imagine the sight on the gulf one could enjoy from up there.

    I’ll be walking up Vesuvius in June when the cruise I’m on stops at Naples. Was inspired by it last year on the same cruise (my mate works on the ship so its a cheapy holiday) so I’m gonna go up it this year. Why – because I’m a nutter and will definately be living on the edge that day!
