Indonesia, a country consisting of over seventeen thousand islands, lies directly below Malaysia and East Asia. Despite its large number of islands, it is only slightly three times less than the size of Texas. The main islands (Sumatra, Java, Kalimantan, Sulawesi, and Irian Jaya) are mostly made up of volcanoes. Only one hundred of the four hundred volcanoes on the islands remain active today; this includes Krakatoa, also known as Krakatau, a volcano that had a violent eruption in 1983. Elevation in Indonesia varies between zero miles above sea level and five thousand thirty miles above sea level, the highest point being Puncak Jaya, the tallest mountain in Indonesia. Coastal plains surround the islands which attract tourists. The largest of the lakes on these islands would be Lake Toba on Sumatra. As for rivers, the longest is Kapaus River on the island of Borneo.
