Lesser Sunda Islands in the context of "Wetar"

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.

Bali (English: /ˈbɑːli/ ; Indonesian: ['bali]; Balinese: ᬩᬮᬶ) is a province of Indonesia and the westernmost of the Lesser Sunda Islands. East of Java and west of Lombok, the province includes the island of Bali and a few smaller offshore islands, notably Nusa Penida, Nusa Lembongan, and Nusa Ceningan to the southeast. The provincial capital, Denpasar, is the most populous city in the Lesser Sunda Islands and the second-largest, after Makassar, in Eastern Indonesia. The Denpasar metropolitan area is the extended metropolitan area around Denpasar. The upland town of Ubud in Greater Denpasar is considered Bali's cultural centre. The province is Indonesia's main tourist destination, with a significant rise in tourism since the 1980s, and has become the country's area of overtourism. Tourism-related business makes up 80% of the Bali economy.

Bali is the only Hindu-majority province in Indonesia, with 86.40% of the population adhering to Balinese Hinduism. It is renowned for its highly developed arts, including traditional and modern dance, sculpture, painting, leather, metalworking, and music. The Indonesian International Film Festival is held every year in Bali. Other international events that have been held in Bali include Miss World 2013, the 2018 Annual Meetings of the International Monetary Fund and the World Bank Group, and the 2022 G20 summit. In March 2017, Tripadvisor named Bali as the world's top destination in its Traveler's Choice award, which it earned once again in January 2021.

Lombok is an island in West Nusa Tenggara province, Indonesia. It forms part of the chain of the Lesser Sunda Islands, with the Lombok Strait separating it from Bali to the west and the Alas Strait between it and Sumbawa to the east. It is roughly circular, with a "tail" (Sekotong Peninsula) to the southwest, about 70 kilometres (43 miles) across and a total area of about 4,566.54 square kilometres (1,763.15 square miles) including smaller offshore islands. The provincial capital and largest city on the island is Mataram.

Lombok is somewhat similar in size and density, and shares some cultural heritage with the neighboring island of Bali to the west. However, it is administratively part of West Nusa Tenggara, along with the larger but less densely populated island of Sumbawa to the east. Lombok is surrounded by a number of smaller islands locally called Gili.

The Greater Sunda Islands (Indonesian and Malay: Kepulauan Sunda Besar) are four tropical islands situated within the Indonesian Archipelago, in the Pacific Ocean. The islands, Borneo, Java, Sulawesi and Sumatra, are internationally recognised for their ecological diversity and rich culture. Together with the Lesser Sunda Islands to their southeast, they comprise the archipelago known as the Sunda Islands.

Mainly part of Indonesia, each island is diverse in its ethnicity, culture and biological attributes. The islands have a long and rich history which has shaped their cultural backgrounds.

Timor (Indonesian: Pulau Timor; Portuguese: Ilha de Timor; Tetum: Illa Timór) is an island at the southern end of Maritime Southeast Asia, in the north of the Timor Sea. The island is divided between the sovereign states of Timor-Leste in the eastern part and Indonesia in the western part. The Indonesian part, known as West Timor, constitutes part of the province of East Nusa Tenggara. Within West Timor lies an exclave of Timor-Leste called Oecusse District. The island covers an area of 30,777 square kilometres (11,883 square miles). The name is a variant of timur, Malay for "east"; it is so called because it lies at the eastern end of the Lesser Sunda Islands. Mainland Australia is less than 500 km away, separated by the Timor Sea.

The Australasian realm is one of eight biogeographic realms that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas.

The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the Oceanian realm.

Jaco Island (Portuguese: Ilha de Jaco, Tetum: Illa Jako, Fataluku: Totina or Tontina) is an uninhabited island in Timor-Leste, a country occupying the eastern end of the island of Timor in the Lesser Sunda Islands in Southeast Asia. It lies off the eastern tip with Cape Cutcha of the island of Timor (Aldeia Pitileti, Suco Tutuala, administrative post Tutuala, municipality Lautém).

Rote Island (Indonesian: Pulau Rote, also called Roti) is an island of Indonesia, part of the East Nusa Tenggara province of the Lesser Sunda Islands. According to legend, this island got its name accidentally when a lost Portuguese sailor arrived and asked a farmer where he was. The surprised farmer, who could not speak Portuguese, introduced himself, "Rote". About 80% of the people of Rote Island in Indonesia are Christian. Christianity is an important part of the community.

Geologically, the Sunda Shelf (/ˈsʌndə/) is a south-eastern extension of the continental shelf of Mainland Southeast Asia. Major landmasses on the shelf include the Indonesian islands of Bali, Borneo, Java, Madura, and Sumatra, as well as their surrounding smaller islands. It covers an area of approximately 1.85 million km. Sea depths over the shelf rarely exceed 50 metres and extensive areas are less than 20 metres resulting in strong bottom friction and strong tidal friction. Steep undersea gradients separate the Sunda Shelf from the Philippines, Sulawesi, and the Lesser Sunda Islands (not including Bali).
