Question: What is the highest elevation in the country Fualopa is located in?

full_context: Document 1: Tuvalu: Tuvalu consists of three reef islands and six true atolls. Its small, scattered group of atolls have poor soil and a total land area of only about 26 square kilometres (10 square miles) making it the fourth smallest country in the world. The islets that form the atolls are very low lying. Nanumanga, Niutao, Niulakita are reef islands and the six true atolls are Funafuti, Nanumea, Nui, Nukufetau, Nukulaelae and Vaitupu. Tuvalu's Exclusive Economic Zone (EEZ) covers an oceanic area of approximately 900,000 km2.
Document 2: Vasafua: Vasafua is an islet of Funafuti, Tuvalu. Vasafua is part of the Funafuti Conservation Area, established in 1996 with the aim of preserving the natural fauna and flora of the area.
Document 3: Tuvalu: Because of the low elevation, the islands that make up this nation are vulnerable to the effects of tropical cyclones and by the threat of current and future sea level rise. The highest elevation is 4.6 metres (15 ft) above sea level on Niulakita, which gives Tuvalu the second-lowest maximum elevation of any country (after the Maldives). The highest elevations are typically in narrow storm dunes on the ocean side of the islands which are prone to overtopping in tropical cyclones, as occurred with Cyclone Bebe, which was a very early-season storm that passed through the Tuvaluan atolls in October 1972. Cyclone Bebe submerged Funafuti, eliminating 90% of structures on the island. Sources of drinking water were contaminated as a result of the system's storm surge and the flooding of the sources of fresh water.
Document 4: Tuvalu: Tuvalu experiences the effects of El Niño and La Niña caused by changes in ocean temperatures in the equatorial and central Pacific. El Niño effects increase the chances of tropical storms and cyclones, while La Niña effects increase the chances of drought. Typically the islands of Tuvalu receive between 200 to 400 mm (8 to 16 in) of rainfall per month. However, in 2011 a weak La Niña effect caused a drought by cooling the surface of the sea around Tuvalu. A state of emergency was declared on 28 September 2011; with rationing of fresh-water on the islands of Funafuti and Nukulaelae. Households on Funafuti and Nukulaelae were restricted to two buckets of fresh water per day (40 litres).
Document 5: Funamanu: Funamanu is a small narrow island that is part of Funafuti atoll in Tuvalu. It is a motu (islet) or very small island and is located 2.6 miles southwestward of the southwest tip of Funafuti. The islet is known to be covered in coconut trees which grow 70 feet high. Te Ava Pua Pua is the passage through the reef, with a least depth of 12.7 metres, between the islets of Funamanu to the north and Fale Fatu to the south, in the southeast of Funafuti atoll.
Document 6: Tepuka: Tepuka is an island eighteen kilometers west of Fongafale, in the northwest of Funafuti, the main atoll of the Oceanian nation of Tuvalu. Te puka, or Pouka, is the name of a tree - "Hernandia peltata".
Document 7: Funafala: Funafala is an islet of Funafuti, Tuvalu that is inhabited by five families, with a church also located on the islet. Funafala means 'the pandanus of Funa', the name of a chief, after whom also the group has been named Funafuti.
Document 8: Tuvalu: The reefs at Funafuti have suffered damage, with 80 per cent of the coral becoming bleached as a consequence of the increase in ocean temperatures and ocean acidification. The coral bleaching, which includes staghorn corals, is attributed to the increase in water temperature that occurred during the El Niños that occurred from 1998–2000 and from 2000–2001. A reef restoration project has investigated reef restoration techniques; and researchers from Japan have investigated rebuilding the coral reefs through the introduction of foraminifera. The project of the Japan International Cooperation Agency is designed to increase the resilience of the Tuvalu coast against sea level rise through ecosystem rehabilitation and regeneration and through support for sand production.
Document 9: Funafuti: Funafuti is an atoll and the capital of the island nation of Tuvalu. It has a population of 6,025 people, making it the country's most populated atoll, with 56.6 percent of Tuvalu's population. It is a narrow sweep of land between 20 and 400 metres (66 and 1,312 feet) wide, encircling a large lagoon (Te Namo) 18 km (11 miles) long and 14 km (9 miles) wide. The average depth in the Funafuti lagoon is about 20 fathoms (36.5 metres or 120 feet). With a surface of 275 square kilometres (106.2 sq mi), it is by far the largest lagoon in Tuvalu. The land area of the 33 islets aggregates to 2.4 square kilometres (0.9 sq mi), less than one percent of the total area of the atoll. Cargo ships can enter Funafuti's lagoon and dock at the port facilities on Fongafale.
Document 10: Fale, Tuvalu: Fale is an islet of Nukufetau, Tuvalu. The traditional history of Nukufetau recalls that in order to protect the atoll from raiders from Tonga, Lagitupu and Laupapa, two aliki (chiefs) protected Fale. Lagitupu and Laupapa created a trap at a place still called Tututekolo, which was beside a path which led to the beach, where they would surprise the raiders and spear them or split their skulls with an axe made from shells.
Document 11: Fualopa: Fualopa is an islet of Funafuti, Tuvalu. It is part of the Funafuti Conservation Area, established in 1996 with the aim of preserving the natural fauna and flora of the area. Fualopa hosts a breeding colony of black noddy ("Anous minutus" or white-capped noddy).
Document 12: Tuvalu: Cyclone Bebe in 1972 caused severe damage to Funafuti. Funafuti's Tepuka Vili Vili islet was devastated by Cyclone Meli in 1979, with all its vegetation and most of its sand swept away during the cyclone. Along with a tropical depression that affected the islands a few days later, Severe Tropical Cyclone Ofa had a major impact on Tuvalu with most islands reporting damage to vegetation and crops. Cyclone Gavin was first identified during 2 March 1997, and was the first of three tropical cyclones to affect Tuvalu during the 1996–97 cyclone season with Cyclones Hina and Keli following later in the season.
Document 13: Tuvalu: The eastern shoreline of Funafuti Lagoon was modified during World War II when the airfield (what is now Funafuti International Airport) was constructed. The coral base of the atoll was used as fill to create the runway. The resulting borrow pits impacted the fresh-water aquifer. In the low areas of Funafuti the sea water can be seen bubbling up through the porous coral rock to form pools with each high tide. Since 1994 a project has been in development to assess the environmental impact of transporting sand from the lagoon to fill all the borrow pits and low-lying areas on Fongafale. In 2014 the Tuvalu Borrow Pits Remediation (BPR) project was approved in order to fill 10 borrow pits, leaving Tafua Pond, which is a natural pond. The New Zealand Government funded the BPR project. The project was carried out in 2015 with 365,000 sqm of sand being dredged from the lagoon to fill the holes and improve living conditions on the island. This project increase the usable land space on Fongafale by eight per cent.
Document 14: Marshall Islands: Population has outstripped the supply of freshwater, usually from rainfall. The northern atolls get 50 inches (1,300 mm) of rainfall annually; the southern atolls about twice that. The threat of drought is commonplace throughout the island chains.
Document 15: Tuvalu: The Tuvalu Government carried out assessments of the damage caused by Cyclone Pam to the islands and has provided medical aid, food as well as assistance for the cleaning-up of storm debris. Government and Non-Government Organisations provided assistance technical, funding and material support to Tuvalu to assist with recovery, including WHO, UNICEF, UNDP, OCHA, World Bank, DFAT, New Zealand Red Cross & IFRC, Fiji National University and governments of New Zealand, Netherlands, UAE, Taiwan and the United States.
