Mount Papandayan
Mount Papandayan is a complex stratovolcano, located in Garut Regency, to the southeast of the city of Bandung in West Java, Indonesia. It is about to the southwest of the town of Garut. At the summit, there are four large craters which contain active fumarole fields. An eruption in 1772 caused the northeast flank to collapse producing a catastrophic debris avalanche that destroyed 40 villages and killed nearly 3,000 people. The eruption truncated the volcano into a broad shape with two peaks and a flat area 1.1 km wide with Alun-Alun crater in the middle, making the mountain appear as a twin volcano; one of the peaks is called Papandayan and the other Mount Puntang. Since 1772, only small phreatic eruptions were recorded before an explosive eruption that began in November 2002. More recently, the volcano has been quite active. On 13 August 2011 the volcano's early warning status was lifted from Level II, "Vigilant" ( id, Waspada) to Level III, "Alert" () following t ...

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 enough to ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

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 pa ...

Tourist Attractions In West Java
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 ...

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]   |

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. ...

Javanese Edelweiss
''Anaphalis javanica'', the Javanese edelweiss, is a flowering plant species endemic to Indonesia. They are found mostly in mountainous regions of Java, southern Sumatra, southern Sulawesi and Lombok. Although a mature plant can reach eight metres in height, most specimens are less than a metre tall. The flower are generally seen between April and August. A bird species, the Javan whistling thrush ('' Myophonus glaucinus''), nests in the plant's branches. Threats Known as ''bunga abadi'' in Indonesian, literally means eternal flower, this plant is popular among tourists. Dried flowers are often sold as souvenirs. This could lead to the destruction of the wild grown species. In the Bromo-Tengger region in East Java this plant is considered extinct. This species is constantly decreasing in number and is currently protected in Gunung Gede Pangrango National Park Mount Gede Pangrango National Park is a national park in West Java, Indonesia. The park is centred on two volcanoes†... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Elfin Forest
Dwarf forest, elfin forest, or pygmy forest is an uncommon ecosystem featuring miniature trees, inhabited by small species of fauna such as rodents and lizards. They are usually located at high elevations, under conditions of sufficient air humidity but poor soil. There are two main dwarf forest ecosystem types, involving different species and environmental characteristics: coastal temperate and montane tropical regions. Temperate coastal dwarf forest is common for parts of Southern California. Montane tropical forests are found across tropical highlands of Central America, northern South America and Southeast Asia. There are also other isolated examples of dwarf forests scattered across the world, while the largest dwarf forest is found in the Philippines. High-elevation tropical dwarf forest High-elevation tropical locations in cloud forests contain mossy wet elfin forests due to high-elevation precipitation. These regions are characterized by low rainfall, with most of the wa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bandung Regency
Bandung Regency (''Kabupaten Bandung'') is an administrative landlocked regency located to the south, southeast, east and northeast of the city of Bandung. The northern parts of the Bandung Regency are effectively part of the Bandung Metropolitan Area (technically the whole of the Regency is within the Metropolitan Area), with the southern third being less urbanized and jutting upwards from the Valley, though not as sharply as the mountain range to the immediate north of Bandung. The Regency is part of the Indonesian province of West Java, and is situated about 75 miles southeast of Jakarta. The town of Soreang is the regency seat. The Regency was reduced in size as first Cimahi City (which became autonomous) and then West Bandung Regency were split off from the regency. In the 2010 Census, the population of the residual area reached 3,178,543 after final adjustments, while the 2020 Census increased the total to 3,623,790; the official estimate as at mid 2021 was 3,666,156, for ...

Kawah Putih
Kawah Putih (Sundanese script, Sundanese: ) ( en, White Crater) is a Volcanic crater lake, crater lake and tourist spot in a volcanic crater about south of Bandung in West Java in Indonesia. Kawah Putih lake (7.10° S 107.24° E) is one of the two craters which make up Mount Patuha, an andesitic stratovolcano (a "composite" volcano). Mount Patuha is one of numerous Volcanism of Java, volcanoes in Java. Kawah Putih crater lake itself represents a relatively stable volcanic system with no records of significant activity since around 1600. The Kawah Putih site was opened to visitors in 1987. The lake is above sea level so the local climate is often quite chilly (temperatures are frequently around ). This makes a brisk change from the humidity of the north Java plain and the capital city of Jakarta. Kawah Putih is a sizeable highly acid lake (pH 0.5-1.3) which changes colour from bluish to whitish green, or brown, depending on the concentration of sulfur and the temperature or the o ...

Mud Pool
A mudpot, or mud pool, is a sort of acidic hot spring, or fumarole, with limited water. It usually takes the form of a pool of bubbling mud. The acid and microorganisms decompose surrounding rock into clay and mud. Description The mud of a mudpot takes the form of a viscous, often bubbling, slurry. As the boiling mud is often squirted over the brims of the mudpot, a sort of mini-volcano of mud starts to build up, sometimes reaching heights of 1 to 1.5 meters. Although mudpots are often called "mud volcanoes", true mud volcanoes are very different in nature. The mud of a mudpot is generally of white to greyish color, but is sometimes stained with reddish or pink spots from iron compounds. When the slurry is particularly colorful, the feature may be referred to as a paint pot. Geology Mudpots form in high-temperature geothermal areas where water is in short supply. The little water that is available rises to the surface at a spot where the soil is rich in volcanic ash, clay, and ...
