Geography of Papua New Guinea
From Wikipedia, the free encyclopedia
The geography of Papua New Guinea describes the eastern half of the island of New Guinea, the islands of New Ireland, New Britain and Bougainville, and smaller nearby islands. Together these make up the nation of Papua New Guinea in tropical Oceania, located at approximately at the western edge of the Pacific Ocean.
Papua New Guinea is largely mountainous, and much of it is covered with tropical rainforest. The Central Range of mountains runs the length of New Guinea, and the highest areas receive snowfall - a rarity in the tropics. Within Papua New Guinea Mount Wilhelm is the highest peak, at 4,509 m. There are several major rivers, notably the Sepik River (1,126 km long), which winds through lowland swamp plains to the north coast, and the Fly River (1,050 km long), which flows through one of the largest swamplands in the world to the south coast.
Papua New Guinea has one land border - that which divides New Guinea island. Across the 820 km border, the western half of New Guinea is officially known as Papua province, governed by Indonesia. There are maritime borders with Australia to the south and Solomon Islands to the south-east.

and the water space area is of: 9,980 km²

Natural hazards: Papua New Guinea is subject to volcanism, as it is situated along the Pacific's "Ring of Fire". Volcanic eruptions are not rare, and is prone to earthquakes, and tsunamis because of this. The volcanic disturbance can often cause sever earthquakes, which in turn can also cause tsunamis. PNG is also prone to landslides, often caused by the deforestation in major forests. The mountainous regions of PNG are the areas most susceptible to landslides causing any damage.
