Mount Dempo
Mount Dempo is the highest stratovolcano in South Sumatra province that rises above Pasumah Plain near Pagar Alam and adjacent with Bengkulu Province. Seven craters are found around the summit. A wide lake is found at the north-west end of the crater complex. Activities present been in 2009 and most recently, May 31, 2022. Historical activity has been confined to being small-to-moderate explosive activity that produced ashfall near the volcano. At 1:54 AM (GMT+7), a small phreatic explosion occurred causing small pyroclastic flows to ride down the northwest slope a few hundred meters downward, resulting to no injuries nor any damage to the surrounding landscape other than the volcano itself, lasting no more than 239s/3m59s. The Royal Rotterdam Lloyd Dutch shipping company named and operated a fine passenger liner named 'Dempo' from 1931 to 1944 between Europe and South Asia.

Bukit Barisan
The Bukit Barisan or the Barisan Mountains are a mountain range on the western side of Sumatra, Indonesia, covering nearly 1,700 km (1,050 mi) from the north to the south of the island. The Bukit Barisan range consists primarily of volcanoes shrouded in dense jungle cover, including Sumatran tropical pine forests on the higher slopes. The highest peak of the range is Mount Kerinci at 3,800 metres (12,467 ft). The Bukit Barisan Selatan National Park is situated towards the southern end of the range Liwa, Indonesia. The name Bukit Barisan actually means "row of hills" or "hills that make a row" in Malay, for the range stretches end to end along the island of Sumatra. There are 35 active volcanoes in Bukit Barisan. The largest volcano is the supervolcano Toba within the 100 km (62 miles) × 30 km (19 miles) Lake Toba, which was created after a caldera collapse (est. in 74,000 Before Present). The eruption is estimated to have been at level ei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Rotterdam Lloyd
The Royal Rotterdam Lloyd (Koninklijke Rotterdamsche Lloyd or KRL) was a Dutch shipping company that was established in Rotterdam between 1883 and 1970. Until 1947 the name was Rotterdamsche Lloyd (RL). In 1970 the KRL merged with several other Dutch shipping companies to form the Nederlandsche Scheepvaart Unie (NSU), known from 1977 as Nedlloyd. History The ''Royal Rotterdam'' was founded on June 15, 1883 with seven ships, housed in joint shipping companies and under the management of Wm. Ruys & Zonen, were united in one company the company's origins date back to 1839 when the Rotterdam shipowner Willem Ruys (1809-1889) set sail for the Dutch East Indies and the Far East. As a result of the opening of the Suez Canal, his son Willem Ruys (1837-1901) expanded the company in 1872 with a steamboat service to Batavia. In 1875 he founded the Partenrederij Stoomboot Reederij "Rotterdamsche Lloyd" himself, whose name was changed in 1881 to Stoomv ...

Mountains Of Sumatra
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

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] |
Active Volcanoes
An active volcano is a volcano which is either erupting or is likely to erupt in the future. An active volcano which is not currently erupting is known as a dormant volcano. Overview Tlocene Epoch. Most volcanoes are situated on the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes. ''Historical time'' (or recorded history) is another timeframe for ''active''. However, the span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less than 300 years, and in Hawaii and New Zealand it is only around 200 years. The incomplete ''Catalogue of the Active Volcanoes of the World'', published in parts between 1951 and 1975 by the International Association of Volcanology, uses this definition, by which there are more than 500 active volcanoes. , the Smithsonian Global Volcanism Program recognizes 560 volcanoes with ...

Volcanoes Of Sumatra
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 ...

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. ...

Volcanic Crater
A volcanic crater is an approximately circular depression in the ground caused by Volcano, volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During Types of volcanic eruptions, volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions, and sometimes of great depth. During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera. Geomorphology In most volcanoes, the crater is situated at the top of a mountain formed from the erupted volcanic deposits such as lava flows and tephra. Volcanoes that terminate in such a summit crater are usually of a conical form. Other volcanic craters may be found on the flanks of volcanoe ...

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 ...
