volcanism: Indonesia contains the most volcanoes of any country in the world - some 76 are historically active; significant volcanic activity occurs on Java, western Sumatra, the Sunda Islands, Halmahera Island, Sulawesi Island, Sangihe Island, and in the Banda Sea; Merapi (elev. 2,968 m, 9,737 ft), Indonesia's most active volcano and in eruption since 2010, has been deemed a "Decade Volcano" by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to its explosive history and close proximity to human populations; other notable historically active volcanoes include Agung, Awu, Karangetang, Krakatau (Krakatoa), Makian, Raung, and Tambora
