Gunung Awu
Mount Awu ( id, Gunung Awu) is the largest volcano in the Sangihe chain, located on Sangir Island in North Sulawesi, Indonesia. Powerful eruptions occurred in 1711, 1812, 1856, 1892 and 1966 with devastating pyroclastic flows and lahars that have resulted in more than 8,000 fatalities altogether. A 4.5 km wide crater is found at the summit and a deep valley forms a passageway for lahars, splitting the flanks from the crater. This is a volcano in the Ring of Fire.

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 ...

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] |
18th-century Volcanic Events
The 18th century lasted from January 1, 1701 (Roman numerals, MDCCI) to December 31, 1800 (Roman numerals, MDCCC). During the 18th century, elements of Age of Enlightenment, Enlightenment thinking culminated in the American Revolution, American, French Revolution, French, and Haitian Revolution, Haitian Revolutions. During the century, History of slavery, slave trading and human trafficking expanded across the shores of the Atlantic Ocean, Atlantic, while declining in Russian Empire, Russia, Qing dynasty, China, and Joseon, Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that Proslavery, supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in Society, human society and the Natural environment, environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th cen ...

19th-century Volcanic Events
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of North Sulawesi
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, Stratum, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountain A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock.

Mountains Of North Sulawesi
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 ...

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. ...

Sangir Island
Sangir Besar, commonly called Sangir Island (with the spelling variants "Sangihe", "Sanghir" or "Sangi"), is an island in the Sangir Islands group. Its Indonesian name literally means "Great Sangir", in reference to the fact that it is the archipelago's main island. It is part of the North Sulawesi province. The main language is the Sangir language. It was the scene of the violent eruption of Gunung Awu volcano on 2 March 1856. The existing mountain was reshaped by the eruption, and flooding was extensive. The death toll was estimated to exceed two thousand, possibly as high as 6,000. Other major eruptions occurred in 1966 and 2004. The critically endangered cerulean flycatcher and Sangihe whistler The Sangihe whistler or Sangihe shrikethrush (''Coracornis sanghirensis'') is a species of bird in the family Pachycephalidae.
