Makian Island
Makian (also Machian), known to local people as Mount Kie Besi, is a volcanic island, one of the Maluku Islands within the province of North Maluku in Indonesia. It lies near the southern end of a chain of volcanic islands off the western coast of the province's major island, Halmahera, and lies between the islands of Moti and Tidore to the north and Kayoa and the Bacan Group to the south. The island, which forms two districts (''Pulau Makian'' and ''Makian Barat'') within South Halmahera Regency of North Maluku Province, covers an area of 91.04 sq.km, and had a population of 12,394 at the 2010 Census, which rose to 14,000 at the 2020 Census. The official estimate as at mid 2023 was 12,525.

List Of Volcanoes In Indonesia
The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Australian plate, Indo-Australian plate. Some of the volcanoes are notable for their eruptions, for instance, Krakatoa for its global effects in 1883, the Lake Toba Caldera for its supervolcano, supervolcanic eruption estimated to have occurred 74,000 Before Present, years before present which was responsible for six years of volcanic winter, and Mount Tambora for the most violent eruption in recorded history in 1815. Volcanoes in Indonesia are part of the Alpide belt, alpida belt and Pacific Ring of Fire. The 150 entries in the list below are grouped into six geographical regions, four of which belong to the volcanoes of the Sunda Arc trench system. The remaining two groups are volcanoes of Halmahera, including its surrounding volcanic islands, and volcanoes of Sulawesi and the Sangihe Islands. The latter group is in one volcanic arc together with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Makian Language
West Makian (also known by the endonym MoiKlamer, Marian; Ger Reesink; and Miriam van Staden. 2008. East Nusantara as a Linguistic Area. In Pieter Muysken (ed.), ''From linguistic areas to areal linguistics'', 95-149. Amsterdam: John Benjamins.) is a divergent North Halmahera language of Indonesia. It is spoken on the coast near Makian Island, and on the western half of that island. West Makian has been strongly influenced by a neighboring Austronesian language or languages to the extent that it was once classified as Austronesian, as East Makian (Taba) still is. As a family-level isolate, it is not closely related to any other language. A brief description of the language can be found in Voorhoeve (1982). Much influence comes from Taba, as well as Malay, Ternate, Dutch, and potentially Portuguese. Phonology Vowels West Makian has 5 or 6 vowels: /a, e, ə, i, o/, and /u/, with /ə/ not recorded by Watuseke. Voorhoeve states that /ə/ is only found in Indonesian loans. ...

Taba Language
Taba (also known as East Makian or Makian Dalam) is a Malayo-Polynesian language of the South Halmahera–West New Guinea group. It is spoken mostly on the islands of Makian, Kayoa and southern Halmahera in North Maluku province of Indonesia by about 20,000 people. Dialects There are minor differences in dialect between all of the villages on Makian island in which Taba is spoken. Most differences affect only a few words. One of the most widespread reflexes is the use of in Waikyon and Waigitang, where in other villages is retained from Proto-South Halmaheran. Geographic distribution As of 2005, ''Ethnologue'' lists Taba as having a speaking population of approximately 20,000; however, it has been argued by linguists that this number could in reality be anywhere between 20,000 and 50,000. The language is predominantly spoken on Eastern Makian island, although it is also found on Southern Mori island, Kayoa islands, Bacan and Obi island and along the west coast of south Halmah ...

Volcanic Explosivity Index
The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The scale is open-ended with the largest eruptions in history given a magnitude of 8. A value of 0 is given for non-explosive eruptions, defined as less than of tephra ejected; and 8 representing a supervolcanic eruption that can eject (240 cubic miles) of tephra and have a cloud column height of over . The scale is logarithmic, with each interval on the scale representing a tenfold increase in observed ejecta criteria, with the exception of between VEI-0, VEI-1 and VEI-2. Classification With indices running from 0 to 8, the VEI associated with an eruption is dependent on how much volcanic materia ...

Eruption
A volcanic eruption occurs when material is expelled from a volcanic vent or fissure. Several types of volcanic eruptions have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three main types of volcanic eruptions. Magmatic eruptions involve the decompression of gas within magma that propels it forward. Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic eruptions, where no fresh magma reaches the surface. Within these broad eruptive types are several subtypes. The weakest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is str ...

Parasitic Cone
A parasitic cone (also adventive cone, satellite cone, satellitic cone or lateral cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano. It forms from eruptions from fractures on the flank of the volcano. These fractures occur because the flank of the volcano is unstable. Eventually, the fractures reach the magma chamber and generate eruptions called flank eruptions, which, in turn, produce a parasitic cone. A parasitic cone can also be formed from a dike or sill cutting up to the surface from the central magma chamber in an area different from the central vent. A peculiar example of multiple parasitic cones is Jeju Island in South Korea. Jeju Island features 368 " oreums" (Korean: ; "mount"), which lie in a roughly lateral line on either side of the island's central dormant shield volcano Hallasan.

Bacan
The Bacan Islands (; ), formerly also known as the Bachans, Bachians, and Batchians, are a group of islands in the Moluccas in Indonesia. They are mountainous and forested, lying south of Ternate and southwest of Halmahera. The islands are administered by the South Halmahera Regency of North Maluku Province. They formerly constituted the Sultanate of Bacan. Bacan (), formerly also known as Bachian or Batchian, is the group's largest island. Bacan Island in 2020 included about 82,387 people, of whom 7,073 lived in the capital Labuha; it is subdivided into seven districts. The second and third-largest islands are Kasiruta and Mandioli. Kasiruta and Mandioli each have over 11,000 inhabitants, and each is subdivided into two districts. A fourth island, Batang Lomang, forms a twelfth district within the group. There are dozens of smaller islands in the group, which had a total population of 84,075 at the 2010 Census, but by the 2020 Census had risen to 111,517.Badan Pusat Stati ...

Maluku Islands
The Maluku Islands ( ; , ) or the Moluccas ( ; ) are an archipelago in the eastern part of Indonesia. Tectonics, Tectonically they are located on the Halmahera Plate within the Molucca Sea Collision Zone. Geographically they are located in West Melanesia. Lying within Wallacea (mostly east of the biogeography, biogeographical Max Carl Wilhelm Weber, Weber Line), the Moluccas have been considered a geographical and cultural intersection of Asia and Oceania. The islands were known as the Spice Islands because of the nutmeg, Nutmeg#Mace, mace, and cloves that were exclusively found there, the presence of which sparked European colonial interests in the 16th century. The Maluku Islands formed a single Provinces of Indonesia, province from Indonesian independence until 1999, when they were split into two provinces. A new province, North Maluku, incorporates the area between Morotai and Sula Islands Regency, Sula, with the arc of islands from Buru and Seram Island, Seram to Wetar rem ...
