Freshwater withdrawal (domestic/industrial/agricultural):
total: 0.1 cu km/yr (56%/43%/1%)

Natural hazards:
active volcanism; situated along the Pacific "Ring of Fire"; the country is subject to frequent and sometimes severe earthquakes; mud slides; tsunamis
volcanism: Papua New Guinea experiences severe volcanic activity; Ulawun (elev. 2,334 m, 7,657 ft), one of Papua New Guinea's potentially most dangerous volcanoes, has been deemed a "Decade Volcano" by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to its explosive history and close proximity to human populations; Rabaul (elev. 688 m, 2,257 ft) destroyed the city of Rabaul in 1937 and 1994; Lamington erupted in 1951 killing 3,000 people; Manam's 2004 eruption forced the island's abandonment; other historically active volcanoes include Bam, Bagana, Garbuna, Karkar, Langila, Lolobau, Long Island, Pago, St. Andrew Strait, Victory, and Waiowa
