Indonesia Geography. Strategically positioned between the Pacific and Indian oceans, Indonesia is an archipelagic nation containing over 18,000 islands. Of those, the larger islands of Sumatra, Java, Kalimantan (which comprises two-thirds of the island of Borneo), Sulawesi, and Irian Jaya are quite mountainous, with some peaks reaching 12,000 ft.
Indonesia is a huge archipelagic country extending 5,120 kilometers from east to west and 1,760 kilometers from north to south. It encompasses 13,667 islands (some sources say as many as 18,000), only 6,000 of which are inhabited.
The explosion alone was heard as far west as Sumatra island, some 1,200 miles (2,000 km) away, and ash falls were recorded on the islands of Borneo, Sulawesi, Java and Maluku. Located along the Ring of Fire, Indonesia has about 400 volcanoes within its borders, with at least 90 still active in some way. The most active volcanoes are Kelut (which has erupted more than 30 times since 1000 AD) and Merapi (which has erupted more than 80 times since 1000 AD) on Java island.
