Mount Raung
The Raung (), or Mount Raung ( jv, ꦒꦸꦤꦸꦁꦫꦲꦸꦁ, Gunung Raung) is one of the most active volcanoes on the island of Java in Indonesia. It is located in the province of East Java and has a and caldera surrounded by a grayish rim. The difference in color of the rim and the flanks of the volcanoes is caused by the rim’s lack of vegetation compared with the healthy and extensive vegetation on the flanks. Raung, standing almost 3,332 metres (10,932 ft) above sea level, is the tallest volcano of this cluster. Although the valleys between the major volcanoes boast fertile, ash-enriched soil for agriculture, available land is very limited. Raung contains centres constructed along a NE to SW line, with Gunung Suket and Gunung Gadung stratovolcanoes being located to the northeast and west, respectively. Mount Raung can be seen from Lovina Beach, Singaraja, North Bali. The normal route climbing is through Bondowoso and Sumber Wringin. Its earliest recorde ...

List Of Peaks By Prominence
This is a list of mountain peaks ordered by their topographic prominence. Terminology The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. The lowest point on that route is the col. For full definitions and explanations of ''topographic prominence'', ''key col'', and ''parent'', see topographic prominence. In particular, the different definitions of the parent of a peak are addressed at length in that article. ''Height'' on the other hand simply means elevation of the summit above sea level. Regarding parents, the ''prominence parent'' of peak A can be found by dividing the island or region in question into territories, by tracing the runoff from the key col (mountain pass) of every peak that is more prominent than peak A. The parent is the peak whose territory peak A resides in. The ''encirclement parent'' is found by tracing the contour below peak A's key col and picking the highe ...

Normal Route
A normal route or normal way (french: voie normale; german: Normalweg) is the most frequently used route for ascending and descending a mountain peak. It is usually the simplest route. Overview In the Alps, routes are classed in the following ways, based on their waymarking, construction and upkeep: * Footpaths (''Fußwege'') *Hiking trails (''Wanderwege'') * Mountain trails (''Bergwege'') * Alpine routes (''Alpine Routen'') *Climbing routes (''Kletterrouten'') and High Alpine routes (''Hochalpine Routen'') in combined rock and ice terrain, (UIAA) graded by difficulty Sometimes the normal route is not the easiest ascent to the summit, but just the one that is most used. There may be technically easier variations. This is especially the case on the Watzmannfrau, the Hochkalter and also Mount Everest. There may be many reasons these easier options are less well-used: * the simplest route is less well known than the normal route (Watzmannfrau). * the technically easiest route is mor ...

Volcanoes Of East 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 ...

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. ...

Idul Fitri
is the popular name for two Islamic official holidays, Eid al-Fitr and Eid al-Adha in Indonesia, and is one of the major national holidays in the country. holiday officially lasts for two days in the Indonesian calendar, although the government usually declares a few days before and after the as a bank holiday. Many individuals or families, especially Muslims take paid time off from their workplace during these days. Etymology ''"Idul Fitri"'' and ''"Idul Adha"'' are Indonesian spelling of Arabic "Eid al-Fitr" and Eid al-Adha. While ''"lebaran"'' is localized name for this festive occasion, the etymology is not clear. It is suggested derived from Javanese word which means "finished", then the word "lebar" is absorbed into Indonesian language with additional suffix "-an", so it becomes a common vocabulary for a celebration when the fasting ritual is "finished", or derived from Sundanese word which means "abundance" or "many" to describe the abundance of foods and delicacies ...

Eruption Of Raung Volcano (2015) From Bali Strait At Dawn
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 eruptio ...

Ultra Prominent Peak
An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence. The term "Ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington (state), Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, 1,518 Ultras have been identified above sea level: 639 in Asia, 356 in North America, 209 in South America, 120 in Europe (including 12 in the Caucasus), 84 in Africa, 69 in Oceania, and 41 in ...
