Tangkuban Parahu
Tangkuban Perahu (also Tangkuban Parahu) is a stratovolcano 30 km north of the city of Bandung, the provincial capital of West Java, Indonesia. It erupted in 1826, 1829, 1842, 1846, 1896, 1910, 1926, 1929, 1952, 1957, 1961, 1965, 1967, 1969, 1983, 2013 and 2019. It is a popular tourist attraction where tourists hike or ride to the edge of the crater to view the hot water springs and boiling mud up close, and buy eggs cooked on the hot surface. Together with Mount Burangrang and Bukit Tunggul, it is a remnant of the ancient Mount Sunda after the plinian eruption caused the Caldera to collapse. In April 2005, the Directorate of Volcanology and Geological Hazard Mitigation raised an alert, forbidding visitors from going up the volcano. "Sensors on the slopes of the two mountains - Anak Krakatoa on the southern tip of Sumatra Island and Tangkuban Perahu in Java - picked up an increase in volcanic activity and a build-up of gases, said government volcanologist Syamsul Rizal."

Ribu
A ribu is a mountain that reaches a topographic prominence of at least . "Ribu" is an Indonesian word meaning "thousand". In Indonesia and Malaysia, three categories of ribus are known according to the absolute height of the peak. The "Sangat Tinggi" (Indonesian for "very high") category is for peaks higher than 3,000 meters, "Tinggi Sedang" (Indonesian for "medium height") for peaks between 2,000 and 3,000 meters, and "Kurang Tinggi" (Indonesian for "less high") for peaks with an elevation of between 1,000 and 2,000 meters. Currently, a total of 270 ribus are known across the Indonesian archipelago, including those in Malaysia and East Timor. Some are popular hikes, such as Mount Rinjani, Mount Semeru, and Mount Kerinci, while others are much more obscure, and some do not even have official names. Some famous Indonesian mountains, such as Mount Bromo and Tangkuban Perahu, are not ribus because they are connected to higher peaks by high passes and therefore do not achieve enoug ...

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 equiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratovolcanoes Of Indonesia
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volcanoes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of West Java
A volcano is a rupture 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 most 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 can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Sangkuriang
Sangkuriang ( Sundanese: ᮞᮀᮊᮥᮛᮤᮃᮀ) is a legend among Sundanese people in Indonesia. The legend tells about the creation of Lake Bandung, Mount Tangkuban Parahu, Mount Burangrang and Mount Bukit Tunggul. The legend of Sangkuriang tells the story of a young man who falls in love with his own mother, which is somewhat comparable to the Greek tragedy Oedipus. From the legend, we can determine how long the Sundanese have been living in Java island. Firmly supported by geological facts, it is predicted that the Sundanese have been living on Java Island since a thousand years BC. The legend of Sangkuriang was almost certainly a story of oral tradition before being written down. The first written reference to Sangkuriang legend appeared in the Bujangga Manik manuscript written on palm leaves at the end of the 15th century or the early 16th century AD. Prince Jaya Pakuan, alias Prince Bujangga Manik or prince Ameng Layaran, visited all of the sacred Hindu sites in Java ... [...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. S ...

Citarum River
The Citarum River ( su, Walungan Citarum) is the longest and largest river in West Java, Indonesia. It is the third longest river in Java, after Solo River, Bengawan Solo and Brantas River, Brantas. It plays an important role in the life of the people of West Java. It has been noted for being considered one of the most water pollution, polluted rivers in the world. History In History of Indonesia, Indonesian history the Citarum is linked with the 4th-century Tarumanagara kingdom, as the kingdom and the river shared the same etymology, derived from the word "tarum" (Sundanese language, Sundanese for Indigofera, indigo plant). The earlier 4th-century BCE prehistoric Buni culture, Buni clay pottery-making culture flourished near the river's mouth. Stone inscriptions, Chinese sources, and archaeological sites such as Batujaya Archaeological Site, Batujaya and Cibuaya suggest that human habitation and civilization flourished in and around the river estuaries and river valley as early as ...

Sundanese Language
Sundanese (: , ; Sundanese script: ) is a Malayo-Polynesian language spoken by the Sundanese. It has approximately 40 million native speakers in the western third of Java; they represent about 15% of Indonesia's total population. Classification According to American linguist Robert Blust, Sundanese is closely related to the Malayic languages, as well as to language groups spoken in Borneo such as the Land Dayak languages or the Kayan–Murik languages, based on high lexical similarities between these languages. History and distribution Sundanese is mainly spoken on the west side of the island of Java, in an area known as Tatar Sunda ( Pasundan). However, Sundanese is also spoken in the western part of Central Java, especially in Brebes and Cilacap Regency, because these areas were previously under the control of the Galuh Kingdom. Many place names in Cilacap are still Sundanese names such as Dayeuhluhur, Cimanggu, Cipari and so on. Until 1600 AD, Sundanese was the ...

Types Of Volcanic Eruptions
Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—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 different types of eruptions: * Magmatic eruptions are the most well-observed type of eruption. They 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 erup ...

Tephra
Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism. Volcanologists also refer to airborne fragments as pyroclasts. Once clasts have fallen to the ground, they remain as tephra unless hot enough to fuse into pyroclastic rock or tuff. Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. When a volcano explodes, it releases a variety of tephra including ash, cinders, and blocks. These layers settle on the land and, over time, sedimentation occurs incorporating these tephra layers into the geologic record. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer. These fossils are later dated by scientists to determine the age of the fossil and its place within the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
