Here, there is a list of most active volcanoes in the world. The volcanoes described below are considered very dangerous due to be included in the decade volcano list.
10. Santa Maria, Guatemala
Santa María, a stratovolcano in the volcanic highlands of southwestern Guatemala, is the site of one of the twentieth century's largest eruptions. It is also the home of Santiaguito, one of the most active lava dome complexes in the world. The group of four lava domes formed at the foot of Santa María twenty years after the volcano's devastating 1902 eruption, and the domes have been growing ever since. The currently active dome, El Caliente, is the site of regular ash-and-gas explosions, and this minor but persistent activity has drawn many tourists to catch a glimpse of explosive silicic eruptions.
9. Galeras, Colombia
Galeras, a stratovolcano in the southwestern part of Colombia, is one of the South American country's most active volcanoes.It summit rises 4,276 meters (14,029 ft) above sea level. Historic records of eruptions at Galeras date back to the 16th century, and the active cone is part of a volcanic complex that has been erupting for more than one million years. Galeras is only a few kilometers from the city of Pasto, and poses an immediate threat to the more than 300,000 people who live there.
8. Mauna Loa, Hawaii
Mauna Loa, the world’s largest volcano, located on the south-central part of the island of Hawaii, Hawaii state, U.S., and a part of Hawaii Volcanoes National Park. One of the largest single mountain masses in the world, Mauna Loa (meaning “Long Mountain” in Hawaiian) rises to 13,677 feet (4,169 metres) above sea level and constitutes half of the island’s area. Its dome is 75 miles (120 km) long and 64 miles (103 km) wide. Moku‘āweoweo, its summit caldera, has an area of nearly 6 square miles (15 square km) and a depth of 600 feet (180 metres). Frequently snowcapped in winter, Mauna Loa is a shield volcano that has erupted some three dozen times since its first well-documented eruption in 1843. Many of its eruptions are confined within Moku‘āweoweo Caldera; others are lower flank eruptions along northeast or southwest fissure zones. During eruptions in 1935 and 1942, U.S. military planes dropped bombs in attempts (that were partially successful) to divert the path of lava flows that threatened the city of Hilo. In June 1950 a 23-day flow from a 13-mile (21-km) fissure in the southwest rift destroyed a small village. Substantial eruptions at the summit occurred in 1975 and 1984.

7. Taal Volcano, Philippines
It's considered one of the world's most dangerous active volcanoes. Just 55 kilometers south of Manila, Philippines Taal Volcano has erupted 30 times since the 16th century, accounting for the deaths of more than 5,000 people.
Yet it's scaled daily by dozens of groups of laid-back tourists.
Perhaps they're calmed by Taal's reputation as the smallest active volcano in the world -- it's just 311 meters tall -- a title that hints at peril yet makes Taal sound relatively unintimidating. Or maybe it's the fact that after eight eruptions in the 1960s and 1970s, Taal Volcano has not vented its fury since 1977. It's also in an incredible location that defies belief.
Taal Volcano sits on an island within a lake within an island, adjacent to the holiday town of Tagaytay, a popular getaway for Manila residents.

5. Mount Nyiragongo, D.R of Congo
It has a 1.2 km diameter summit caldera containing the world's most active and largest lava lake.
Nyiragongo is infamous for its extremely fluid lava that runs as water when the lava lake drains. On January 17, 2002, Nyiragongo erupted and the lava lake drained from fissures on its western flanks. The city centre of the Goma town, the capital of the East Virunga province, had been destroyed by voluninous lava flows. 200,000 people were left homeless, adding to the human desaster caused by frequent civil wars.

4. Mount Merapi, Indonesia
Mount Merapi, Indonesian Gunung Merapi, volcanic mountain peak located near the centre of the island of Java, Indonesia. The volcano is about 20 miles (32 km) north of Yogyakarta and somewhat farther south of Semarang. Merapi (“Mountain of Fire”) rises to 9,551 feet (2,911 metres) and has steep slopes with dense vegetation on its lower flanks. It is the most active of Indonesia’s 130 active volcanoes. One of its largest eruptions occurred in 1006 and spread ash throughout central Java. Other major eruptions were those of 1786, 1822, 1872, 1930, and 1976. Almost half of Merapi’s eruptions have been accompanied by pyroclastic flows, or nuées ardentes, which are clouds of superheated gases and incandescent solid particles. In the eruption of Nov. 22, 1994, the release of a pyroclastic flow killed 64 people. A series of eruptions of the volcano in late 2010, which included pyroclastic flows, killed scores of people, injured dozens more, and forced tens of thousands to evacuate the area.
3. Sakurajima, Japan
Sakurajima (also spelled Sakurashima or Sakura-jima, 桜島 in Japanese) volcano in southern Kyushu is one of the most active volcanoes in the world, and one of the few that are at present in constant (persistant) activity. Its ongoing typical activity range from strong strombolian to large ash explosions every 4-24 hours.
The volcano is located across Kagoshima Bay only 8 km east of the city of Kagoshima with a population of half a million. Sakurajima's eruptive history has been recorded since the 8th century. It has frequently deposited ash on Kagoshima, and due to its explosive potential, considered a very dangerous volcano and closely monitored.
The largest historical eruptions of Sakurajima took place during 1471-76 and in 1914.
2. Mount Vesuvius, Italy
Vesuvius, also called Mount Vesuvius or Italian Vesuvio, active volcano that rises above the Bay of Naples on the plain of Campania in southern Italy. Its western base rests almost upon the bay. The height of the cone in 2013 was 4,203 feet (1,281 metres), but it varies considerably after each major eruption. At about 1,968 feet (about 600 metres), a high semicircular ridge, called Mount Somma, begins, girding the cone on the north and rising to 3,714 feet (1,132 metres). Between Mount Somma and the cone is the Valle del Gigante (Giant’s Valley). At the summit of the cone is a large crater about 1,000 feet (about 305 metres) deep and 2,000 feet (about 610 metres) across; it was formed in the eruption of 1944. More than two million people live in the vicinity of Vesuvius and on its lower slopes. There are industrial towns along the coast of the Bay of Naples and small agricultural centres on the northern slopes.
1. Eyjafjallajökull, Iceland
Icelandic for “Island mountain glacier”, this volcano is one of the smaller ice caps of Iceland. The ice cap covers the caldera of a volcano with a summit elevation of 1,666 meters (5,466 ft). The 2010 eruption caused enormous disruption to air travel across western and northern Europe. About 20 countries closed their airspace to commercial jet traffic and it affected more than 100,000 travelers
