Gamalama
Gamalama is a near-conical stratovolcano that comprises the entire Ternate island in Indonesia. The island lies off the western shore of Halmahera island in the north of the Maluku Islands. For centuries, Ternate was a center of Portuguese Empire, Portuguese and Dutch East Indies Company, Dutch forts for spice trade, which have accounted for thorough reports of Gamalama's volcanic activities. An eruption in 1775 caused the deaths of approximately 1300 people. On December 4, 2011 Mount Gamalama erupted, ejecting material up to 2,000 meters into the air. Thousands of residents in nearby Ternate City fled due to ash and dust particles raining down on the town. Finally on December 27 some 4 people died and dozens injured from debris falls (lahar) after a month of activity. More eruptions occurred in September 2012. An eruption on December 18, 2014, deposited five centimeters of ash on the runway of Babullah Airport in Ternate, closing the airport. See also * List of volcan ...

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 ...

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 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 Antarctica. ...

Mountains Of Indonesia
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 ...

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] |
Babullah Airport
Sultan Babullah Airport ( id, Bandar Udara Sultan Babullah) also known as Ternate Airport, is located in the Indonesian province of North Maluku, close to the city of Ternate. The airport is named after the Indonesian warrior Sultan Babullah of Ternate (1528–1583). The airport serves as the main access to the province, with a high flow of both passengers and cargo. In the long run, government policy regarding air transport development plans will be aimed at the development of infrastructure and service at the airport, allowing for further routes to and from the city. History Sultan Babullah Airport was opened in 1971 but officially commenced operations for civilian aircraft in 1978, becoming the main form of transportation to North Maluku. The airport is located roughly 6 km from the city centre. In 2005, a terminal was inaugurated in order to accommodate the growing number of passengers. The airport set about further expansion in 2013, inaugurating a new and larger termi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lahar
A lahar (, from jv, ꦮ꧀ꦭꦲꦂ) is a violent type of mudflow or debris flow composed of a slurry of pyroclastic material, rocky debris and water. The material flows down from a volcano, typically along a river valley. Lahars are extremely destructive: they can flow tens of metres per second, they have been known to be up to deep, and large flows tend to destroy any structures in their path. Notable lahars include those at Mount Pinatubo and Nevado del Ruiz, the latter of which killed thousands of people in the town of Armero. Etymology The word ''lahar'' is of Javanese origin. Berend George Escher introduced it as a geological term in 1922. Description The word ''lahar'' is a general term for a flowing mixture of water and pyroclastic debris. It does not refer to a particular rheology or sediment concentration. Lahars can occur as normal stream flows (sediment concentration of less than 30%), hyper-concentrated stream flows (sediment concentration between 30 ...

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 ...
