Atolls of the Maldives in the context of "Addu Atoll"

Southeast Asia is the geographical southeastern region of Asia, consisting of the regions that are situated south of China, east of the Indian subcontinent, and northwest of mainland Australia, which is part of Oceania. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of 26 atolls of the Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is entirely in the Northern Hemisphere. Timor-Leste and the southern portion of Indonesia are the parts of Southeast Asia that lie south of the equator.

The region lies near the intersection of geological plates, with both heavy seismic and volcanic activities. The Sunda plate is the main plate of the region, featuring almost all Southeast Asian countries except Myanmar, northern Thailand, northern Laos, northern Vietnam, and northern Luzon of the Philippines, while the Sunda plate only includes western Indonesia to as far east as the Indonesian province of Bali. The mountain ranges in Myanmar, Thailand, Peninsular Malaysia, and the Indonesian islands of Sumatra, Java, Bali, Lesser Sunda Islands, and Timor are part of the Alpide belt, while the islands of the Philippines and Indonesia as well as Timor-Leste are part of the Pacific Ring of Fire. Both seismic belts meet in Indonesia, causing the region to have relatively high occurrences of earthquakes and volcanic eruptions, particularly in the Philippines and Indonesia.

Maldives, officially the Republic of Maldives, and historically known as the Maldive Islands, is an archipelagic country in South Asia, located in the eastern Arabian Sea, within the northern Indian Ocean. Maldives is southwest of Sri Lanka and India, about 750 kilometres (470 miles; 400 nautical miles) from the Asian continent's mainland. Maldives' chain of 26 atolls stretches across the equator from Ihavandhippolhu Atoll in the north to Addu Atoll in the south.

Maldives is the smallest country in Asia. Its land area is only 298 square kilometres (115 sq mi), but this is spread over roughly 90,000 square kilometres (35,000 sq mi) of the sea, making it one of the world's most spatially dispersed sovereign states. With a population of 515,132 in the 2022 census, it is the second least populous country in Asia and the ninth-smallest country by area, but also one of the most densely populated countries. Maldives has an average ground-level elevation of around 1.5 metres (4 ft 11 in) above sea level, and a highest natural point of only 2.4 metres (7 ft 10 in), making it the world's lowest-lying country. Some sources state the highest point, Mount Villingili, as 5.1 metres or 17 feet.

Gaafu Alifu (also known as Northern Huvadhu Atoll or Huvadhu Atholhu Uthuruburi, ހުވަދުއަތޮޅު އުތުރުބުރި) is an administrative division of the Maldives created on February 8, 1962, when Huvadhu Atoll was divided into two districts. Gaafu Alifu corresponds to the northeastern section of this large natural atoll north of the line extending between the channels of Footukandu and Vaarulu Kandu. The capital of this district is Vilingili.

NOTE: Haa Alifu, Haa Dhaalu, Shaviyani, Noonu, Raa, Baa, Kaafu, etc. (including Gaafu Alif) are code letters assigned to the present administrative divisions of the Maldives. They are not the proper names of the natural atolls that make up these divisions. Some atolls are divided into two administrative divisions while other divisions are made up of two or more natural atolls. The order followed by the code letters is from North to South, beginning with the first letters of the Thaana alphabet used in Dhivehi. These code letters are not accurate from the geographical and cultural point of view. However, they have become popular among tourists and foreigners in the Maldives who find them easier to pronounce than the true atoll names in Dhivehi, (save a few exceptions, like Ari Atoll).

Gaafu Dhaalu (also known as Southern Huvadhu Atoll or Huvadhu Atholhu Dhekunuburi, ހުވަދުއަތޮޅު ދެކުނުބުރި) is an administrative district of the Maldives formed by the southwestern section of Huvadhu Atoll. It was created on February 8, 1962, when Huvadhu Atoll was divided into two districts. Gaafu Dhaalu corresponds to the Southwestern section of this large natural atoll, south of the line extending between the channels of Footukandu and Vaarulu Kandu. The capital of this region is Thinadhoo (Thenadhoo). There are 153 islands in this district, 10 of which are inhabited. This district is located about 340 kilometers south of the capital Malé.
