Vesuvius with its ominous crater, which measures about 1500 feet in circumference, is enough to discourage anyone trying to get too close.

Mount Vesuvius is an active explosive volcano (currently in a quiescent state) situated in Campania in the territory of the homonymous national park, established in 1996. He is currently the top 1281 m. and lies within a caldera 4 km in diameter. The caldera is what remains of the former volcano (Somma) after the great eruption of 79 AD eruption that created the caldera where he formed the Vesuvius.

is a volcano particularly interesting for its history and the frequency of its eruptions. It is part of the mountain Sum. It is located slightly inland from the coast of the Gulf of Naples, for a about six miles east of Naples.

Viewed from afar, with its gentle slopes and its dashboard form seems created specifically for the make Naples more harmonious city in the world, but just observe it from 'high to be aware of its awfulness. "I saw formidable mountain murderous" I called the Leopards and in fact, like all volcanoes, Mount Vesuvius is a destroyer. With the unique distinction of being the more methodical volcano in the world. Since that first eruption of which we hear in 79 AD that destroyed Pompeii and Herculaneum, we can count to this day fifty. The last was in 1944 after the Vesuvius stopped smoking.

But even without his towering plume is always a volcano, and that his menacing crater, which measures about 1500 feet in circumference, is enough to discourage anyone trying to get too close. Far more extensive, but less dangerous than Vesuvius, is instead the crater of Mount Somma with its 75 km. Circumference along which the Trail runs Circumvesuviana.

Vesuvius, in fact, consists of two craters and one outside - belonging to the Monte Somma that surrounds the base - and one inside, that is the Great Cone. For this reason, Vesuvius is a volcano "to fence". The valley from Dante's landscape that separates the two cones is called "The Hall of the Horse." An 'other valley, even more frightening, is called "The Valley of Hell."

Vesuvius is a glance of rare beauty in the landscape of the Gulf, especially when viewed from the sea with the city skyline. A famous picture postcard image taken from the hill of Posillipo did come right in the collective imagination of the city of Naples. However, the Vesuvio has a primacy in the world: it is the first volcano that has been systematically studied (by the will of the ruling house of Bourbon) and today is the most monitored volcano and studied.

origins dating back to 1841 (by order of King Ferdinand II of the Two Sicilies) the construction of an observatory (which still works, even if only as an annex of the most modern facilities located in Naples) and we can say that the volcanology, as a true and their scientific research, was born in those years.

Even in more recent years, we are the first decades of the twentieth century, when the U.S. decided to establish an observatory in Hawaii, he remade the experience of Vesuvius.

Since 1944 they have never had its eruptions. However, as the volcano considered in a quiescent state, some legislative measures have identified a red zone comprising 18 municipalities (those National Park of Vesuvius: Boscoreale Boscotrecase, Ottaviano, Pollena Trocchia, Herculaneum, Vesuvius San Jose, San Gennaro San Sebastiano al Vesuvio, Anastasia, Somma Vesuvius, Terzigno, Torre Del Greek, Trecase, Massa di Somma well Cercola, Pompei Portici, San Giorgio a Cremano, Torre Annunziata), the National Department of Civil Protection, in collaboration with the scientific community and local authorities, has prepared a contingency plan which is updated continuously. Municipalities also puts in place cyclically civil protection exercises to prepare the population of the eruption event.

Recently, the Region has set up incentives to facilitate the decongestion of the area at greatest risk. This measure of economic incentives, however, has not had the desired result because the populations of the municipalities have shown resistance to leave the sites. In fact, almost everyone says it would have been better (instead of using the funds for these incentives exodus) to create more "escape routes" from the volcano and establish an even more proactive monitoring system to know in advance of any eruptions. In addition, the populations have required substantial changes agli interventi legislativi relativi alla "zona rossa" (ad esempio la diversificazione dei vincoli tra la zona vesuviana marittima da quella della zona interna "sommana" e, ancora, la diversificazione in base alla altitudine).

Eruzioni del Vesuvio in tempi storici .

Dopo l'eruzione del 79 - che fu l'ultima delle eruzioni "pliniane" ed anche la prima dei tempi storici-, il Vesuvio ha avuto innumerevoli eruzioni, di svariati tipi, qui sotto cronologicamente elencate:
