Indonesia - Geography
Here, let us take a look at the Geography of Indonesia.
note 1: 13,466 islands are in the archipelago, of which 922 are permanently inhabited; Indonesia is the world's largest country composed solely of islands; the country straddles the equator and occupies a strategic location 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
