full_context: Document 1: Kiribati: Kiribati maintains close relations with its Pacific neighbours, Australia, New Zealand, Republic of China (Taiwan), Japan and Fiji. The first three of these provide the majority of the country's foreign aid. Taiwan and Japan also have specified-period licences to fish in Kiribati's waters. There are four resident diplomatic missions headquartered in Kiribati: the Embassies of the Republic of China (Taiwan) and Cuba and the High Commissions of Australia and New Zealand.
Document 2: Pacific War: The official policy of the U.S. Government is that Thailand was not an ally of the Axis, and that the United States was not at war with Thailand. The policy of the U.S. Government ever since 1945 has been to treat Thailand not as a former enemy, but rather as a country which had been forced into certain actions by Japanese blackmail, before being occupied by Japanese troops. Thailand has been treated by the United States in the same way as such other Axis-occupied countries as Belgium, Czechoslovakia, Denmark, Greece, Norway, Poland, and the Netherlands.
Document 3: Metis Shoal: Metis Shoal is a shoal at the top of a submarine volcano, located between the islands of Kao and Late in Tonga. When the volcano erupted in 1995 a 43 metre high island formed, composed of a solid lava dome above the surface. It was washed away soon after.
Document 4: Langila: Langila is one of the most active volcanoes of New Britain, Papua New Guinea. It consists of four overlapping volcanic cones on the eastern flank of an older extinct volcano, Talawe. Talawe is the largest volcano in Cape Gloucester. There have been dozens of recorded eruptions since the 19th century from three separate volcanic craters at the summit of Langila. The most recent eruptive cycle of Langila began in August 2006 and continued into early 2007. Volcanic activity at Langila consists of Strombo-Vulcanian and Vulcanian eruptions and lava flows. Langila is one of the most active volcanoes in the Bismark archipelago. The smallest crater is crater number 3.
Document 5: Oceania: Biogeographically, as a synonym for the Australasian ecozone and the Pacific ecozone (Melanesia, Polynesia, and Micronesia), with New Zealand forming the south - western corner of the Polynesian Triangle. To note, New Zealand may also be considered part of Australasia, despite being traditionally part of Polynesia. As an ecozone, Oceania includes all of Micronesia, Fiji, and all of Polynesia except New Zealand. New Zealand, along with New Guinea and nearby islands, part of the Philippine islands, Australia, the Solomon Islands, Vanuatu, and New Caledonia, constitute the separate Australasian ecozone. In the geopolitical conception used by the United Nations, International Olympic Committee, and many atlases, Oceania includes Australia and the nations of the Pacific from Papua New Guinea east, but not Indonesian New Guinea.
Document 6: Curacoa volcano: Curacoa is a submarine volcano located south of the Curacoa Reef in northern Tonga. Eruptions were observed in 1973 and 1979 from two separate vents. The 1973 eruption produced a large raft of dacitic pumice, and had a volcanic explosivity index (VEI) of 3.
Document 7: Near East: The Foreign and Commonwealth Office of United Kingdom recognises a Middle East and North Africa region, but not a Near East. Their original Middle East consumed the Near East as far as the Red Sea, ceded India to the Asia and Oceania region, and went into partnership with North Africa as far as the Atlantic.
Document 8: Lōʻihi Seamount: Lōihi Seamount (also known as Lōʻihi) is an active submarine volcano about 35 km (22 mi) off the southeast coast of the island of Hawaii. The top of the seamount is about 975 m (3,000 ft) below sea level. This seamount is on the flank of Mauna Loa, the largest shield volcano on Earth. Lōihi, meaning ``long ''in Hawaiian, is the newest volcano in the Hawaiian - Emperor seamount chain, a string of volcanoes that stretches over 5,800 km (3,600 mi) northwest of Lōʻihi. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Lōʻihi and the other volcanoes of the Hawaiian - Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Lōihi is the only Hawaiian volcano in the deep submarine preshield stage of development.
Document 9: Teide: If measured from the ocean floor, it is at 7,500 m (24,600 ft) the highest volcano in the world base - to - peak outside of the Hawaiian Islands, and is described by UNESCO and NASA as Earth's third - tallest volcanic structure. Teide's elevation makes Tenerife the tenth highest island in the world. Teide is an active volcano: its most recent eruption occurred in 1909 from the El Chinyero vent on the northwestern Santiago rift. The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano because of its history of destructive eruptions and its proximity to several large towns, of which the closest are Garachico, Icod de los Vinos and Puerto de la Cruz. Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.
Document 10: Mount Tongkoko: Mount Tongkoko or Mount Tangkoko is a stratovolcano in the north of Sulawesi, Indonesia. Its summit has an elongated deep crater. On the east flank there is a flat lava dome Batu Angus. Historical records only show eruptions in the nineteenth century.

Document 12: Mapu a Vaea: The Mapu a Vaea or "Whistle of the Noble" are natural blowholes on the island of Tongatapu in the village of Houma in the Kingdom of Tonga. When waves crash into the reef, natural channels in the volcanic rock allow water to forcefully blow through and create a plume-like effect. It is one of the highlights of the tours around the island of Tongatapu. "Vaea" is the name of the Honorable Vaea Family of nearby Houma.
