note – [s] after country name indicates river source; [m] after country name indicates river mouth

Population distribution

major concentration on the island of Java, which is considered one of the most densely populated places on earth; of the outer islands (those surrounding Java and Bali), Sumatra contains some of the most significant clusters, particularly in the south near the Selat Sunda, and along the northeastern coast near Medan; the cities of Makasar (Sulawesi), Banjarmasin (Kalimantan) are also heavily populated

Natural hazards

occasional floods; severe droughts; tsunamis; earthquakes; volcanoes; forest fires

volcanism: Indonesia contains the most volcanoes of any country in the world - some 76 are historically active; significant volcanic activity occurs on Java, Sumatra, the Sunda Islands, Halmahera Island, Sulawesi Island, Sangihe Island, and in the Banda Sea; Merapi (2,968 m), 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; on 22 December 2018, a large explosion and flank collapse destroyed most of the 338 m high island of Anak Krakatau (Child of Krakatau) and generated a deadly tsunami inundating portions of western Java and southern Sumatra leaving more than 400 dead; other notable historically active volcanoes include Agung, Awu, Karangetang, Krakatau (Krakatoa), Makian, Raung, Sinabung, and Tambora; see note 2 under "Geography - note"

Geography - note

note 1: according to Indonesia's National Coordinating Agency for Survey and Mapping, the total number of islands in the archipelago is 13,466, of which 922 are permanently inhabited (Indonesia is the world's largest country comprised solely of islands); the country straddles the equator and occupies a strategic location astride or along major sea lanes from the Indian Ocean to the Pacific Ocean

note 2: Indonesia is one of the countries along the Ring of Fire, a belt of active volcanoes and earthquake epicenters bordering the Pacific Ocean; up to 90% of the world's earthquakes and some 75% of the world's volcanoes occur within the Ring of Fire; 80% of tsunamis, caused by volcanic or seismic events, occur within the "Pacific Ring of Fire"

note 3: despite having the fourth largest population in the world, Indonesia is the most heavily forested region on earth after the Amazon

note 4: two major food crops apparently developed on the island of New Guinea: bananas and sugarcane
