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.
