Ojos del Salado COUNTRYFEETMETERS ARGENTINA / CHILE226156893 Nevado Ojos del Salado is a stratovolcano in the Andes on the Argentina–Chile border and the highest active volcano in the world at 6,893 m (22,615 ft). It is also the second highest mountain in the Western Hemisphere and Southern Hemisphere and the highest in Chile. Despite the generally dry conditions, there is a permanent crater lake about 100 m (330 ft) in diameter at an elevation of 6,390 m (20,960 ft) on the eastern side of the mountain. This is most likely the highest lake of any kind in the world.The ascent of Ojos del Salado is mostly a hike except for the final section to the summit which is a difficult scramble that may require ropes. The first ascent was made in 1937 by Jan Alfred Szczepański and Justyn Wojsznis, members of a Polish expedition in the Andes. Mount Sidley COUNTRYFEETMETERS ANTARCTICA137174181 Mount Sidley is the highest dormant volcano in Antarctica, a member of the Volcanic Seven Summits. It is a massive, mainly snow-covered shield volcano which is the highest of the five volcanic mountains that comprise the Executive Committee Range of Marie Byrd Land. The feature is marked by a 5 km wide caldera on the southern side and stands NE of Mount Waesche in the southern part of the range.The mountain was discovered by Rear Admiral Richard E. Byrd on an airplane flight, November 18, 1934, and named by him for Mabelle E. Sidley, the daughter of William Horlick who was a contributor to the 1933–35 Byrd Antarctic Expedition. The first recorded ascent of Mount Sidley was by New Zealander Bill Atkinson on January 11, 1990. Mount Fuji COUNTRYFEETMETERS JAPAN123893776 Mount Fuji, located on Honshū, is the highest volcano in Japan at 3776,24 m (12,389 ft), 2nd-highest peak of an island (volcanic) in Asia, and 7th-highest peak of an island in the world. It is a dormant stratovolcano that last erupted in 1707–1708. Mount Fuji lies about 100 kilometers (60 mi) south-west of Tokyo, and can be seen from there on a clear day.Mount Fuji’s exceptionally symmetrical cone, which is snow-capped for about 5 months a year, is commonly used as a symbol of Japan and it is frequently depicted in art and photographs, as well as visited by sightseers and climbers. It is thought that the first recorded ascent was in 663 by an anonymous monk. The first ascent by a foreigner was by Sir Rutherford Alcock in September 1868. Mount Etna COUNTRYFEETMETERS ITALY109123326 Mount Etna, or Etna, is an active stratovolcano on the east coast of Sicily, Italy. It is the highest active volcano in Europe outside the Caucasus. It is currently 3,326 m (10,912 ft) high, though this varies with summit eruptions. It is the highest peak in Italy south of the Alps. In Greek Mythology, the deadly monster Typhon was trapped under this mountain by Zeus, the god of the sky and thunder and king of gods, and the forges of Hephaestus were said also to be underneath it.Mount Etna is one of the world’s most active volcanoes and is in an almost constant state of activity. The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south. In June 2013, it was added to the list of UNESCO World Heritage Sites. Mount Vesuvius COUNTRYFEETMETERS ITALY42031281 Mount Vesuvius is a somma-stratovolcano located on the Gulf of Naples in Campania, 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, Oplontis and Stabiae, as well as several other settlements. The eruption ejected a cloud of stones, ashes and volcanic gases to a height of 33 km (21 mi), spewing molten rock and pulverized pumice at the rate of 6×105 cubic metres (7.8×105 cu yd) per second, ultimately releasing a hundred thousand times the thermal energy released by the Hiroshima-Nagasaki bombings. More than 1,000 people died in the eruption, but exact numbers are unknown. Taal Volcano COUNTRYFEETMETERS PHILIPPINES1020311 Taal Volcano is a complex volcano located on the island of Luzon in the Philippines. It is the second most active volcano in the Philippines with 33 historical eruptions. All of these eruptions are concentrated on Volcano Island, an island near the middle of Taal Lake. The lake partially fills Taal Caldera, which was formed by prehistoric eruptions between 140,000 and 5,380 BP. Viewed from the Tagaytay Ridge in Cavite, Taal Volcano and Lake presents one of the most picturesque and attractive views in the Philippines.It is located about 50 kilometres (31 miles) south of the capital of the country, the city of Manila. With its highest elevation at only 311 m (1,020 ft), Taal is of the lowest active volcano in the world.
