Indonesia

Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania, 
Between the Indian and Pacific oceans. It consists of over 17,000 islands including Sumatra, Java, Sulawesi and parts of Borneo and New Guinea. Indonesia is the world’s largest archipelagic state and the 14th largest country by area, at, 1,904,569 square kilometres (735,358 square miles). Indonesia is the southernmost country in Asia. The country lies between latitudes 11°S and 6°N and longitudes 95°E and 141°E. A transcontinental country spanning Southeast Asia and Oceania, it is the world's largest archipelagic state, extending 5,120 kilometres (3,181 mi) from east to west and 1,760 kilometres (1,094 mi) from north to south. The country's Coordinating Ministry for Maritime and Investments Affairs says Indonesia has 17,504 islands (with 16,056 registered at the UN) scattered over both sides of the equator, around 6,000 of which are inhabited. The largest are Sumatra, Java, Borneo (shared with Brunei and Malaysia), Sulawesi, and New Guinea (shared with Papua New Guinea). Indonesia shares land borders with Malaysia on Borneo and Sebatik, Papua New Guinea on the island of New Guinea, East Timor on the island of Timor, and maritime borders with Singapore, Malaysia, Vietnam, the Philippines, Palau, and Australia. Indonesia lies along the equator, and its climate tends to be relatively even year-round. Indonesia has two seasons—a dry season and a wet season—with no extremes of summer or winter. For most parts of Indonesia, the dry season falls between May and October, while the wet season falls between November and April. Indonesia's climate is almost entirely tropical, dominated by the tropical rainforest climate found on every large island of Indonesia. Tectonically, most of Indonesia's area is highly unstable, making it a site of numerous volcanoes and frequent earthquakes. It lies on the Pacific Ring of Fire, where the Indo-Australian Plate and the Pacific Plate are pushed under the Eurasian Plate, where they melt at about 100 kilometres (62 miles) deep. A string of volcanoes runs through Sumatra, Java, Bali and Nusa Tenggara, and then to the Banda Islands of Maluku to north-eastern Sulawesi. Of the 400 volcanoes, around 130 are active.
