is a volcano on Tenerife in the Canary Islands. Its 3,718-metre (12,198 ft) summit is the highest point in Spain and the highest point above sea level in the islands of the Atlantic. At 7,500 m (24,600 ft) from its base on the ocean floor, it is the third highest volcano on a volcanic ocean island in the world afterMauna Kea, Mauna Loa and others in Hawaii. [2] Its elevation makes Tenerife the tenth highest island in the world. It remainsactive: its most recent eruption occurred in 1909 from the El Chinyero vent on the northwestern Santiago rift. The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano [3] because of its history of destructive eruptions and its proximity to several large towns, of which the closest are Garachico, Icod de los Vinos and Puerto de la Cruz. Teide, Pico Viejoand Montaña Blanca form the Central Volcanic Complex of Tenerife. The volcano and its surroundings comprise Teide National Park, which has an area of 18,900 hectares (47,000 acres) and was named a World Heritage Site by UNESCO on June 28, 2007. [4] It is one of the most visited national parks in the world, with a total of 2.8 million visitors, according to the Instituto Canario de Estadística (ISTAC). [5] [6] In 2013 it was the ninth most visited national park in the world. [7] The Teide is the most visited natural wonder of Spain. Ulawun is a basaltic and andesitic stratovolcano situated on the island of New Britain , Papua New Guinea , about 130 km southwest of Rabaul . It is the highest mountain in the Bismarck Archipelago at 2,334 metres (7,657 ft), and one of the most active volcanoes in Papua New Guinea. The first recorded eruption of Ulawun was by William Dampier in 1700; there have been 22 recorded eruptions since the 18th century. Several thousand people live near the volcano. Mount Unzen (雲雲雲 Unzen-dake ? ) is an active volcanic group of several overlapping stratovolcanoes , near the city ofShimabara , Nagasaki Prefecture , on the island of Kyūshū , Japan 's southernmost main island. In 1792, the collapse of one of its several lava domes triggered a megatsunami that killed about 15,000 people in Japan's worst-ever volcanic-related disaster . The volcano was most recently active from 1990

 is a volcano on Tenerife in the Canary Islands. Its 3,718-metre (12,198 ft) summit is the highest

point in Spain and the highest point above sea level in the islands of the Atlantic. At 7,500 m

(24,600 ft) from its base on the ocean floor, it is the third highest volcano on a volcanic ocean island

in the world afterMauna Kea, Mauna Loa and others in Hawaii.[2] Its elevation makes Tenerife

the tenth highest island in the world. It remainsactive: its most recent eruption occurred in 1909 from

the El Chinyero vent on the northwestern Santiago rift. The United Nations Committee for Disaster

Mitigation designated Teide a Decade Volcano[3] because of its history of destructive eruptions and

its proximity to several large towns, of which the closest are Garachico, Icod de los Vinos and Puerto

de la Cruz. Teide, Pico Viejoand Montaña Blanca form the Central Volcanic Complex of Tenerife.

The volcano and its surroundings comprise Teide National Park, which has an area of 18,900

hectares (47,000 acres) and was named a World Heritage Site by UNESCO on June 28, 2007.[4] It is

one of the most visited national parks in the world, with a total of 2.8 million visitors, according to the

Instituto Canario de Estadística (ISTAC).[5][6] In 2013 it was the ninth most visited national park in the

world.[7] The Teide is the most visited natural wonder of Spain.

Ulawun is a basaltic and andesitic stratovolcano situated on the island of New Britain, Papua New Guinea, about 130 km southwest of Rabaul. It is the highest mountain in the Bismarck Archipelago at 2,334 metres (7,657 ft), and one of the most active volcanoes in Papua New Guinea. The first recorded eruption of Ulawun was by William Dampier in 1700; there have been 22 recorded eruptions since the 18th century. Several thousand people live near the volcano.

Mount Unzen (雲仙岳 Unzen-dake?) is an active volcanic group of several

overlapping stratovolcanoes, near the city ofShimabara, Nagasaki Prefecture, on the island

of Kyūshū, Japan's southernmost main island.

In 1792, the collapse of one of its several lava domes triggered a megatsunami that killed about

15,000 people in Japan's worst-ever volcanic-related disaster. The volcano was most recently active

from 1990 to 1995, and a large eruption in 1991 generated a pyroclastic flow that killed 43 people,

including three volcanologists.

Currently its highest peaks are Fugen-dake (普賢岳?) at 1,359 metres (4,459 ft) and Heisei-

shinzan (平成新山?) at 1,486 metres (4,875 ft). The latter emerged during the eruptions of the early,

eponymous Heisei era (1989–).

Mount Vesuvius (/vɨˈsuːviəs/; Italian: Monte Vesuvio [ˈmonte veˈzuːvjo], Latin: Mons Vesuvius [mõːs

wɛˈsʊwɪ.ʊs]) is astratovolcano in the Gulf of Naples, Italy, about 9 km (5.6 mi) east of Naples and a

short distance from the shore. It is one of several volcanoes which form the Campanian volcanic arc.

Vesuvius consists of a large cone partially encircled by the steep rim of a summit caldera caused by

the collapse of an earlier and originally much higher structure.

Mount Vesuvius is best known for its eruption in AD 79 that led to the burying and destruction of

the Roman cities of Pompeii,Herculaneum and several other settlements. That eruption ejected a

cloud of stones, ash and fumes to a height of 33 km (20.5 mi), spewing molten rock and

pulverized pumice at the rate of 1.5 million tons per second, ultimately releasing a hundred thousand

times the thermal energy released by the Hiroshima bombing.[1] An estimated 16,000 people died

due to hydrothermal pyroclastic flows .[2] The only surviving eyewitness account of the event consists

of two letters by Pliny the Younger to the historian Tacitus.[3]

Vesuvius has erupted many times since and is the only volcano on the European mainland to have

erupted within the last hundred years. Today, it is regarded as one of the most dangerous volcanoes

in the world because of the population of 3,000,000 people living nearby and its tendency towards

explosive (Plinian) eruptions. It is the most densely populated volcanic region in the world.[4]
