Sirung Volcano, Pantar Island, Alor Archipelago, Indonesia
Mount Sirung ( id, Gunung Sirung) is an active volcano complex volcano located on Pantar Island in the Alor archipelago of the eastern Indonesian province of Nusa Tenggara Timor. The crater rim can be reached by an easy hike from the village of Kakamauta. Inside the crater is a large sulphurous crater lake and several active steam vents. The last major eruption occurred 1970, and regular gas and clastic eruptions have occurred since 2004. A small eruption beginning May 12, 2012 triggered an evacuation of an area within a 1.5 km radius of the caldera.

Pantar Island
Pantar ( id, Pulau Pantar) is the second largest island in the Indonesian Alor Archipelago, after Alor. To the east is the island of Alor and other small islands in the archipelago; to the west is the Alor Strait, which separates it from the Solor Archipelago. To the south is the Ombai Strait, and away, the island of Timor. To the north is the Banda Sea. Pantar is about north-to-south, and varies from in east–west width. It has an area of . The main towns on the island are Baranusa and Kabir. Administratively, the island is part of the Alor Regency. Geography The island consists of two distinct geographic zones. The eastern zone is dominated by a range of verdant hills which drop steeply to the coast of the Alor Strait. The western zone is relatively flat, consisting of a plain which gently slopes to the west from Mount Sirung, an active volcano. The western zone is characteristically drier and much less densely populated than the eastern zone. Owing to its relatively l ...

Volcanic Crater Lake
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the crater rim, is filled by water. The water may come from precipitation, groundwater circulation (often hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the upper portion of the lake is contained only by its adjacent natural volcanic dam; continued leakage through or surface outflow ac ...

Volcanoes Of The Lesser Sunda Islands
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 ...

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 ...

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. ...

Eruption
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 erupti ...

East Nusa Tenggara
East Nusa Tenggara ( id, Nusa Tenggara Timur – NTT; pt, Sonda Oriental) is the southernmost province of Indonesia. It comprises the eastern portion of the Lesser Sunda Islands, facing the Indian Ocean in the south and the Flores Sea in the north. It consists of more than 500 islands, with the largest ones being Sumba, Flores, and the western part of Timor; the latter shares a land border with the separate nation of East Timor. The province is subdivided into twenty-one regencies and the regency-level city of Kupang, which is the capital and largest city. A Christian-majority region, East Nusa Tenggara is the only Indonesian province where Roman Catholicism is the predominant religion. The province has a total area of 47,931.54 km2 and a population of 5,325,566 at the 2020 Census; the official estimate as at mid 2021 was 5,387,738. Economically, East Nusa Tenggara still remains one of the least developed provinces in Indonesia. It currently focuses on expanding the touris ...

Crater Rim
The rim or edge of an impact crater is the part that extends above the height of the local surface, usually in a circular or elliptical pattern. In a more specific sense, the rim may refer to the circular or elliptical edge that represents the uppermost tip of this raised portion. If there is no raised portion, the rim simply refers to the inside edge of the curve where the flat surface meets the curve of the crater bottom. Simple craters Smaller, simple craters retain rim geometries similar to the features of many craters found on the Moon and the planet Mercury. Complex craters Large craters are those with a diameter greater than 2.3 km, and are distinguished by central uplifts within the impact zone. These larger (also called “complex”) craters can form rims up to several hundred meters in height. A process to consider when determining the exact height of a crater rim is that melt may have been pushed over the crest of the initial rim from the initial impact, ther ...
