Outer Banda Arc
The Banda Arc (main arc, Inner, and Outer) is a dual chain of islands in eastern Indonesia that is around 2,300 km long. It is the result of the collision of a continent and an intra-oceanic island arc. The presently active volcanic arc is mounted on stretched continental and oceanic crust whereas the associated subduction trench is underlain by continental crust, which has subducted deep enough to contaminate the volcanic arc with continental melts. The island of Timor is notable for the lack of volcanic activity. This is due to the island representing the zone of fore-arc and continental collision which prevents volcanic activity from occurring. The convergence of the Indo-Australian Plate tectonics, plates and Eurasia resulted in the formation of the Sunda and Banda island arcs. The transitional zone between the arcs is located south of Flores, Flores Island and is characterized by the change in the Tectonics, tectonic regime along the boundary in the Timor Region. Geol ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to Planetary habitability, harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering Water distribution on Earth, 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large Ice sheet, sheets of ice at Polar regions of Earth, Earth's polar polar desert, deserts retain more water than Earth's groundwater, lakes, rivers, and Water vapor#In Earth's atmosphere, atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's outer core, Earth has a liquid outer core that generates a ...

Savu Island
Savu (, also known as Sabu, Havu, and Hawu) is the largest of a group of three islands, situated midway between Sumba and Rote, west of Timor, in Indonesia's eastern province, East Nusa Tenggara. Ferries connect the islands to Waingapu on Sumba, Ende on Flores, and Kupang in West Timor. Flying to Savu through Susi Air from Kupang, Ende, and Waingapu is also possible. Geography The Savu Islands (Indonesian: ''Kepulauan Sawu'') include Rai Hawu (or Savu), Rai Jua, and Rai Dana. The three islands are fringed by coral reefs and sandy beaches. Rai Hawu is the principal island. Rai Jua is a smaller island west of Rai Hawu. Rai Dana is a small, uninhabited island, situated 30 km southwest of Rai Jua. From April to October, deep ocean swells pound the southern coastlines. The land is covered for the most part by grassland and palms. The climate of this island is tropical savanna (''Aw'') with dry months for much of the year because of the dry winds which blow from Austra ...

Damar Island
Damer, or Damar, (), also called Kenli Island, is a small volcano, volcanic island in the Barat Daya Islands group in Indonesia's Maluku (Indonesian province), Maluku province, on the southern side of the Banda Sea. It is flanked by four smaller uninhabited islands - one to the east (Layeni), one to the west (Nus Leur) and two to the south (Terbang Utari and Terbang Selatan). Together they are called the Damar Islands, and constitute one administrative district within the Maluku Barat Daya Regency, lying on the undersea ridge which forms the most easterly extension of the Lesser Sunda Islands. Continuing the line of the ridge further to the northeast are several small and remote islands at increasing distances from Damer Island; these are Mount Teon, Teon Island, Mount Nila, Nila Island, tiny 'Nil Desperandum' islet, Mount Serua, Serua Island (and its offshore islet of Kekeh-Besar) and - far to the north and administered as part of Maluku Tengah Regency - Mount Manuk, Manuk Island; ...

Solor Archipelago
The Solor Archipelago (; ) is a group of islands in the Lesser Sunda Islands, Indonesia, lying to the east of Flores and the west of the Alor Strait and the Alor Archipelago. To the north is the west part of the Banda Sea, while to the south across the Savu Sea lies the island of Timor.

Barat Daya Islands
The Barat Daya Islands (; ) are a group of islands in the Maluku province of Indonesia. The Indonesian phrase ''barat daya'' means 'south-west'. Geography These islands are located off the eastern end of East Timor. Wetar is the largest island in the group.

Seram Island
Seram (formerly spelled Ceram; also Seran or Serang) is the largest and main island of Maluku province of Indonesia, despite Ambon Island's historical importance. It is located just north of the smaller Ambon Island and a few other adjacent islands, such as Saparua, Haruku, Nusa Laut and the Banda Islands. Geography and geology Seram is traversed by a central mountain range, the highest point of which, Mount Binaiya, is covered with dense rain forests. Its remarkably complex geology is because of its location at the meeting of several tectonic microplates, which have been described as "one of the most tectonically complex areas on Earth". Seram falls on its microplate, which has been twisted around by 80° in the last 8 million years by the relatively faster movement of the Papua microplate. Meanwhile, along with the northward push of the Australian Plate, this has resulted in the uplift that gives north-central Seram peaks of over 3000 m. On the island, there are import ...
