Volcanology Of Indonesia
Indonesia is a volcanically active country, containing numerous major volcanoes. It has the most volcanoes of any country in the world, with 76 volcanoes that have erupted at least 1,171 times in total within historical times. The Smithsonian Institution has 141 Indonesian entries in its volcano database. Indonesia has around 130 active volcanoes that are part of the Pacific Ring of Fire, and it has suffered the highest numbers of eruptions resulting in fatalities, damage to arable land, debris flows, tsunamis, lava domes, and pyroclastic flows. Indonesia's most active volcanoes are Kelut and Mount Merapi on the island of Java. The majority of Indonesia's volcano are located on a 3,000 km long chain called the Sunda Arc. Here, the subduction of the Indian Ocean crust underneath the Asian Plate produced most of these volcanoes. History Volcanic eruptions The most severe eruptions on Earth in historical times took place in Indonesia. In 1815, the giant eruption of Mount Ta ...

Map Indonesia Volcanoes
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 supervolcanic eruption estimated to have occurred 74,000 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 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 the Philippine volcanoes. The most active volcano is Mount Merapi on Java. ...

Makian
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 84.36 sq.km, and had a population of 12,394 at the 2010 Census, which rose to 14,000 at the 2020 Census. The island is wide, and its high summit consists of a large wide crater, with a small lake on its Northeast side. There are four parasitic cones on the western slopes of Makian. Makian volcano is also known as Mount Kiebesi (or Kie Besi). Volcanic history Makian volcano has had infrequent, but violent eruptions that destroyed villages o ...

Galunggung
Mount Galunggung (Indonesian: ''Gunung Galunggung'', formerly spelled ''Galoen-gong'') is an active stratovolcano in West Java, Indonesia, around southeast of the West Java provincial capital, Bandung (or around to the east of the West Java town of Tasikmalaya). Mount Galunggung is part of the Sunda Arc extending through Sumatra, Java and the Lesser Sunda Islands, which has resulted from the subduction of the Australian plate beneath the Eurasian plate. For the first time since 1982 after eruptions finished and conditions seemed normal, on February 12, 2012, the status was upgraded to Alert based on changes in conditions. On 28 May 2012, it was lowered from 2 back to 1 (On a scale of 1–4). 1822 eruption Galunggung had its first historical eruption in 1822 that produced pyroclastic flows and lahars that killed 4,011 people. Hazardous eruption of 1982 The last major eruption on Galunggung was in 1982, which had a Volcanic Explosivity Index of 4 and indirectly killed 18 ...

Volcanological Survey Of Indonesia
Volcanological Survey of Indonesia is the official Indonesian government agency under Ministry of Energy and Mineral Resources which are responsible for investigating, recording, and warning about volcanoes within the Indonesian region of responsibility and geological hazard mitigation. The full official Indonesian name is the ''Pusat Vulkanologi dan Mitigasi Bencana Geologi'' (English: ''Vulcanology and Geological Hazard Mitigation Center''), often abbreviated to PVMBG. It is based in Bandung in West Java. It was preceded by the ''Netherlands East Indies Volcanological Survey''. It has also been known as the ''Direktorat Vulcanologi''. Its main publication has been known as ''Berita Berkala vulkanologi''.

Lampung
Lampung (Lampung: ), officially the Province of Lampung ( id, Provinsi Lampung) is a province of Indonesia. It is located on the southern tip of the island of Sumatra. It has a short border with the province of Bengkulu to the northwest, and a longer border with the province of South Sumatra to the north. It is the original home of the Lampung people, who speak their own language, and possess their own written script. Its capital is Bandar Lampung. The province covers a land area of 35,376 sq.km and had a population of 7,608,405 at the 2010 census, 9,007,848 at the 2020 census, and 9,081,792 according to the official estimates for mid 2021,with three-quarters of that being descendants of Javanese, Madurese, and Balinese migrants. These migrants came from more densely populated islands, in search of available land, as well as being part of the national government's Indonesian transmigration program, of which Lampung was one of the earliest and most significant transmigrati ...

Krakatoa
Krakatoa (), also transcribed (), is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group (Krakatoa archipelago) comprising four islands. Two, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the famous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption. In 1927, a fourth island, Anak Krakatoa, or "Child of Krakatoa", emerged from the caldera formed in 1883. There has been new eruptive activity since the late 20th century, with a large collapse causing a deadly tsunami in December 2018. Historical significance The most notable eruptions of Krakatoa culminated in a series of massive explosions over 26–27 August 1883, which were among the most violent volcanic events in recorded history. With an estimated Volcanic Explosivity Index (VEI) of 6, the eruption was equivalen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Tambora
Mount Tambora, or Tomboro, is an active stratovolcano in West Nusa Tenggara, Indonesia. Located on Sumbawa in the Lesser Sunda Islands, it was formed by the active subduction zones beneath it. Before 1815, its elevation reached more than high, making it one of the tallest peaks in the Indonesian archipelago. Tambora violently erupted in a series of eruptions beginning 5 April, 1815, culminating in the largest eruption in recorded human history and the largest of the Holocene (10,000 years ago to present). The magma chamber under Tambora had been drained by previous eruptions and underwent several centuries of dormancy as it refilled. Volcanic activity reached a peak that year, culminating in an explosive eruption. The explosion was heard on Sumatra island, more than away. Heavy volcanic ash rains were observed as far away as Borneo, Sulawesi, Java, and Maluku islands, and the maximum elevation of Tambora was reduced from about to . Although estimates vary, the death ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunda Arc
The Sunda Arc is a volcanic arc that produced the volcanoes that form the topographic spine of the islands of Sumatra, Nusa Tenggara, and Java, the Sunda Strait and the Lesser Sunda Islands. The Sunda Arc begins at Sumatra and ends at Flores, and is adjacent to the Banda Arc. The Sunda Arc is formed via the subduction of the Indo-Australian Plate beneath the Sunda and Burma plates at a velocity of 63–70 mm/year. Formation and geologic setting Mid-oceanic ridge basalts (MORB) form most of the oceanic basin south of Sunda, according to geodynamic studies. These plates began to converge in the Early Miocene. The Indo-Australian Plate is subducting beneath the Eurasian Plate with the dip angle of 49-56 degrees. The slab subducting under Java is continuous down to the lower mantle. However, the slab appears to beak apart under Sumatra Island''.'' Earthquake depth records indicate that there is no deep seismic activity in Sumatra, likely due to the age of the subducting ...
