Recently Active Volcanoes
A volcano which has erupted Lava, pyroclastic material or gases as a significant event in the Twentieth Century. With date of last eruption. Fumaroles, mud pots, hot springs and other continuing "minor" geothermal "extrusions" are excluded.
"Decade Volcanoes" are 16 which have been identified by the International association of Volcanology and chemistery of the Earth's Interior (IAVCEI) as being worthy of particular study in light of their history of large, destructive eruptions and proximity to populated areas.

- Archipiélago de Revillagigedo: San Benedicto had a major eruption as recently as 1952-3 Link
- Galapagos Islands: One of the world?s most active volcanic areas, with more than 50 eruptions in the past 200 years. Six of the volcanoes are still active (1 on Fernandina and 5 on Isabela). The most recent explosion was Cerro Azul on Isabela in September of 1998.

- Sangay National Park: Tungurahua "During the past 1300 years eruptive episodes were generally once per century, and commenced with .... pyroclastic flows, followed by lava flows.. . This cycle was observed in the largest historic eruptions in 1773, 1886 and 1916-1918". There were also recent eruptions in 1999-2008 and 1944". Eruptions in January 2008 forced the evacuation of 1000 people. Two large eruptions occurred on 6th February 2008 with ash to 47,000 ft altitude. Sangay is one of the world's most active volcanoes with a current active cycle from 1934 to present. On 12th August 1976 and eruption killed two people and seriously injured three, from a British expedition team.
- Surtsey: The 1963 eruption began 130 m below sea level and reached the surface in November. Eruptions continued until June 1967 when it had formed an island with an area of 2.7 sq km. Erosion had reduced the island size to 1.4 sq km in 2007
- Teide National Park: 1909 from the El Chinyero vent on the Santiago (northwestern) rift. "Volcanic unrest occurred at the volcano in January 2005. Carbon dioxide emissions rose from 75 to 354 tons per day, and hydrogen sulfide emissions rose from 35 to 152 tons per day". A "Decade Volcano"
- Tongariro National Park: Ngauruhoe is the main active vent in the park with eruptions rarely more than 9 years apart. It has been quiet since 1975 -the longest such period in recorded history

- Virunga National Park: Nyiragongo and nearby Nyamuragira are together responsible for 40% of Africa's historical volcanic eruptions. There were major events in 1977 and 2002. Mt Nyirangongo is a "Decade Volcano"
- Volcanoes of Kamchatka: According to the original AB 1996 evaluation "Kamchatka has 29 Active volcanoes of which 19 are within the nominated area". The 2001 extension is said to have added another cluster of 12 (No it doesn't add up!). Avachinsky is one of the most active - It has erupted at least 17 times in the recorded history of Kamchatka. There was a major eruption in 1945. The last one was 2001. Together with nearby Koryaksky it is a "Decade Volcano"
