Il Vesuvio \u00e8 il vulcano pi\u00f9 famoso della terra, uno dei pi\u00f9 studiati ed \u00e8 anche uno dei pi\u00f9 pericolosi poich\u00e9 il vasto territorio che si estende alle sue pendici ha visto la costruzione di case fino a 700 metri di altura. E\u2019 un tipico esempio di vulcano a recinto costituito da un cono esterno tronco, Monte Somma (1133 metri), con cinta craterica in gran parte demolita entro la quale si trova un cono pi\u00f9 piccolo rappresentato dal Vesuvio (1281 metri), separati da un avvallamento denominato Valle del Gigante, parte dell’antica caldera, dove in seguito, presumibilmente durante l’eruzione del 79 d.C., si form\u00f2 il Gran Cono o Vesuvio.<\/p>\n
La Valle del Gigante \u00e8 suddivisa a sua volta in Atrio del Cavallo ad ovest e Valle dell’Inferno ad est. Il recinto del Somma \u00e8 ben conservato per tutta la sua parte settentrionale, infatti \u00e8 stato nei tempi storici meno esposto alla furia devastatrice del vulcano, perch\u00e9 riparato dall’altezza della parete interna che ha impedito il deflusso di lave sulle sue pendici. I pendii, variamente degradanti, sono solcati da profondi valloni radiali prodotti dall’erosione delle acque meteoriche. Le sue pareti dalla parte del cono si presentano a picco. Tutta la sezione \u00e8 poi disseminata di spuntoni e dicchi di roccia vulcanica scura. Il vecchio orlo craterico \u00e8 un susseguirsi di cime dette cognoli. Mentre l’altezza del Somma ed il suo profilo si sono conservati uguali nei secoli, l’altezza ed il profilo del Vesuvio hanno subito variazioni notevoli, a causa delle successive eruzioni, con innalzamenti ed abbassamenti. Il Vesuvio \u00e8 un caratteristico vulcano poligenico e misto, ossia costituito da lave di composizione chimica diversa (ad esempio trachiti, tefriti, leucititi) e formato sia da colate di lava sia da depositi piroclastici. Tutte le zone alle pendici della montagna sono da considerarsi formate da terreni trasportati da lave di fango che scendono dagli scoscesi pendii nelle stagioni piovose attraverso profondi e stretti valloni detti alvei o pi\u00f9 comunemente lagni. Gli alti argini sono formati da cumuli di scorie laviche, che precipitati allo stato incandescente e dilagati verso le basse pendici, si rivelano ora a causa del loro materiale fertile, ricco di silicio e potassio, preziosi per la vegetazione. Nelle giornate pi\u00f9 fredde la condensazione dei vapori rende visibili le fumarole presenti in numerosi punti della parete interna del cratere.<\/p>\n
Proseguendo lungo il bordo del cratere, guardando verso il mare si coglie l’intera estensione della parte meridionale del vulcano e, in giornate con buona visibilit\u00e0, tutto il Golfo di Napoli dalla Penisola Sorrentina e Capri fino a Capo Miseno, Procida e Ischia. E’ inevitabile notare anche la sconsiderata espansione urbanistica che risale lungo le pendici del vulcano.<\/p>\n","modified":"2018-03-05T11:01:33","color":"","icon":"","noDetails":false,"noInteraction":false,"taxonomy":{"webmapp_category":[15]},"accessibility":{"mobility":{"check":false,"description":""},"hearing":{"check":false,"description":""},"vision":{"check":false,"description":""},"cognitive":{"check":false,"description":""},"food":{"check":false,"description":""}},"locale":"it","source":"http:\/\/vn.be.webmapp.it\/wp-json\/wp\/v2\/poi\/7663","wp_edit":"http:\/\/vn.be.webmapp.it\/wp-admin\/post.php?post=7663&action=edit","translations":{"en":{"id":7666,"name":"Vesuvio","web":"http:\/\/vn.be.webmapp.it\/\/vesuvio\/?lang=en","source":"http:\/\/vn.be.webmapp.it\/wp-json\/wp\/v2\/poi\/7666","description":"
Mt. Vesuvius is the most famous volcano on eart, one of the most studied and one of the most dangerous for the important population living on its slopes until 700m of height.; it\u00a0dominates the Bay of Naples with its characteristic cone. It is a typical example of a volcano in a volcano made by an outer broken cone, Mt. Somma (1133 metres) with a crateric belt most of which is destroyed. In it there is a smaller cone, the Mt. Vesuvius (1281 metres), divided by lowering named Valle del Gigante (Giants Valley), a part of the ancient caldron where in a later period, perhaps during the 79 A.D. eruption, the Gran Cono (Great Cone) or Mt. Vesuvius arose.<\/p>\n
The Valle del Gigante is still divided in Atrio del Cavallo on the west and the Valle dell’Inferno on the east. The Somma’s ancient crater is well preserved as far as its entire northern part is concerned, in fact in historic times it was less exposed to the volcano’s devastating violence, because it was well protected by the height of the internal face that has prevented the downflow of lava on its slopes. The slopes, which vary in their steepness, are furrowed by profound radial grooves produced by the erosion of the meteoric waters. The whole section is then characterized by dikes and fringes of dark volcanic rock. The old crater edge is a stream of summits called cognoli. While the height of mount Somma and its profile have remained the same for centuries, the height and the profile of the mount Vesuvius have suffered considerable variation, because of the following eruptions, with raisings and lowerings. Mt. Vesuvius is a characteristic polygenic mixed volcano, meaning that it is constituted by lava of different chemical composition (for example trachytes, tephrites, leucitites) and formed either by casting of lava or pyroclastic deposits.<\/p>\n
All the zones at the slopes of the mountain are formed by transported earth of lava mud which goes down from the steep slopes in the rainy seasons through deep and narrow grooves called channels or more commonly “lagni”. The high embankments are formed by piles of lavic scoriae, which precipitated in incandescent state and spread towards the low slopes, proving precious for the vegetation thanks to their fertile material, rich in silicon and potassium. Proceeding along the rim of the crater, one can observe the whole extent of the southern part of the volcano and, during days with good visibility, it is possible to see the entire gulf of Naples, from the Sorrento peninsula to Cape Miseno, Procida and Ischia. It is also possible to note the large number of buildings which have been built on the vulnerable flanks of the mountain.<\/p>\n"},"fr":{"id":29212,"name":"Le V\u00e9suve","web":"http:\/\/vn.be.webmapp.it\/\/le-vesuve\/?lang=fr","source":"http:\/\/vn.be.webmapp.it\/wp-json\/wp\/v2\/poi\/29212","description":"
Le V\u00e9suve est un volcan d’une hauteur de 1 280 m. environ, bordant la baie de Naples. Il a \u00e9t\u00e9 responsable, le 24 ao\u00fbt 79 de l’\u00e8re chr\u00e9tienne, de la destruction des villes de Pomp\u00e9i, Herculanum et Stabies, ensevelies sous une pluie de cendres et de boue qui, ainsi, les a conserv\u00e9es.Le c\u00f4ne du V\u00e9suve. Le volcan est compos\u00e9 par deux parties : la premi\u00e8re constitue le mont Somma (\u00e9teint depuis des si\u00e8cles) et la seconde le c\u00f4ne du V\u00e9suve. <\/p>\n
C’est en effet un volcan de type explosif dot\u00e9 d’un crat\u00e8re conique tronqu\u00e9 de 300 m. de profondeur pour 400 m. de diam\u00e8tre. Ce crat\u00e8re est cependant bouch\u00e9: la lave se trouve \u00e0 une dizaine de kilom\u00e8tres en dessous. En effet, s’il n’est actuellement plus en \u00e9ruption, il reste en activit\u00e9 : les secousses telluriques sont importantes (plus de 700 par an) et des fumerolles continuent de s’\u00e9chapper (qu’on peut particuli\u00e8rement bien voir dans le site de la Solfatara). Il est donc sous surveillance constante. Le V\u00e9suve a fait son entr\u00e9e dans l\u2019histoire des Hommes, en 79 ap. J-C. <\/p>\n
\u00c0 cette \u00e9poque, l\u2019empire romain est prosp\u00e8re, et le golfe de Naples est l\u2019une des plus riches provinces de l\u2019Empire. Les villes comme Pomp\u00e9\u00ef, Herculanum se sont install\u00e9es au pied du V\u00e9suve, dans un site apparemment enchanteur. Le 24 ao\u00fbt 79, apr\u00e8s un long sommeil de plusieurs si\u00e8cles, le V\u00e9suve se r\u00e9veille et, en quelques heures, il recouvre Pomp\u00e9\u00ef d\u2019un linceul de pierres ponces et enrobe Herculanum de coul\u00e9es de boue. Le r\u00e9cit de cette \u00e9ruption nous est d\u2019ailleurs parvenu avec la description de Pline le Jeune.<\/p>\n
Apr\u00e8s cet \u00e9pisode tragique, des informations parcellaires rapportent plusieurs \u00e9ruptions en : 203, 472, 512, 685, 787, 968, 991, 999, 1007, 1037, 1139. Ensuite, le V\u00e9suve entre dans une longue p\u00e9riode de l\u00e9thargie d\u2019environ 500 ans. Cette ” lacune d\u2019\u00e9ruption ” pourrait aussi t\u00e9moigner d\u2019un manque de curiosit\u00e9 des ” savants ” de l\u2019\u00e9poque. Cependant, en 1538, l\u2019\u00e9ruption du Monte Nuovo aux Champs Phl\u00e9gr\u00e9ens, juste \u00e0 l\u2019ouest de Naples, est bien relat\u00e9e. Le V\u00e9suve se r\u00e9veille \u00e0 nouveau le 16 d\u00e9cembre 1631, en une quinzaine de jours ses explosions, ses coul\u00e9es de lave et de boue d\u00e9vastent de nombreux villages. <\/p>\n
Plus de 4 000 personnes y trouvent la mort. L\u2019activit\u00e9 \u00e9ruptive du V\u00e9suve se caract\u00e9risera par des \u00e9ruptions pouvant durer plusieurs ann\u00e9es entrecoup\u00e9es de courtes phases de repos (le plus long r\u00e9pit durera 7 ans). Le V\u00e9suve sera \u00e0 l’origine de nombreuses vocations de volcanologues comme William Hamilton. Les \u00e9ruptions vont ainsi se succ\u00e9der : 1650, 1707, 1737, 1760, 1767, 1779, 1794, 1806, 1810, 1817 1822, 1831, 1834, 1839, 1850, 1855, 1858, 1861, 1868, 1872, 1906, 1929, 1932.<\/p>\n"}},"web":"http:\/\/vn.be.webmapp.it\/poi\/vesuvio\/","sequence":1},"geometry":{"type":"Point","coordinates":[14.422613337651,40.823099939519814]}},{"type":"Feature","properties":{"id":7068,"name":"Hotel Palazzo Salgar","description":"
