Vesuvius

Stratovulcano · Italy · 1281 m

Mount Vesuvius behind city of Naples. The modern cone of Vesuvius is flanked on the left by Monte Somma, the rim of a caldera that formed about 17,000 years ago. Eight major explosive eruptions have occurred since, including the 79 CE eruption that destroyed Pompeii and other towns. A period of frequent, long-duration eruptions began in 1631 and the latest eruption of Vesuvius was in 1944.

Sintesi geologica

One of the world's most noted volcanoes, Vesuvius (Vesuvio) forms a dramatic backdrop to the Bay of Naples. The active cone was constructed within a large caldera of the older Monte Somma edifice, thought to have formed incrementally beginning about 17,000 years ago. The Monte Somma caldera wall has channeled lava flows and pyroclastic flows primarily to the south and west. Eight major explosive eruptions have taken place in the last 17,000 years, often accompanied by large pyroclastic flows and surges, such as during the 79 CE Pompeii eruption. Intermittent eruptions since 79 CE were followed by a period of frequent long-term explosive and effusive eruptions between 1631 and 1944. The large 1631 eruption produced pyroclastic flows that reached as far as the coast and caused great destruction. Many towns are located on the flanks, and several million people live within areas that could be affected by eruptions.

Sintesi da Wikipedia

Il Vesuvio è uno stratovulcano situato in Italia, in posizione dominante rispetto al golfo di Napoli, in Campania. La sua forma attuale è il risultato della fusione con un vulcano più antico, il Monte Somma: il cono vulcanico si è sviluppato all'interno della caldera formatasi dal crollo della parte superiore del Somma a causa di potenti eruzioni esplosive, tra cui spicca quella del 79 d.C.
