Mount Agung
Mount Agung (, ) is an active volcano in Karangasem Regency, Bali, Indonesia. It is located southeast of Mount Batur volcano, also in Bali. It is the highest point on Bali, and dominates the surrounding area, influencing the climate, especially rainfall patterns. From a distance, the mountain appears to be perfectly conical. From the peak of the mountain, it is possible to see the peak of Mount Rinjani on the nearby island of Lombok, to the east, although both mountains are frequently covered in clouds. Agung is a stratovolcano, with a large and deep crater. Its most recent eruptions occurred from 2017–2019. History of eruptions 1843 eruption Agung erupted in 1843, as recorded in a report by Heinrich Zollinger: 1963–64 eruption The eruption of 1963 was one of the largest and most devastating eruptions in Indonesia's history. On February 18, 1963, local residents heard loud explosions and saw clouds rising from the crater of Mount Agung. On February 24, lava beg ...

Global Volcanism Program
The Smithsonian Institution's Global Volcanism Program (GVP) documents Earth's volcanoes and their eruptive history during the Quaternary Period of Earth's geologic history, with particular emphasis on volcanic activity during the Holocene Epoch (the last 11,700 years). The mission of the GVP is to document, understand, and disseminate information about global volcanic activity. Global Volcanism Program Database The GVP gathers information and reports on current eruptions from around the world, and maintains a database repository on active volcanoes, their eruptions and their eruption histories. In this way, a global context for the planet's active volcanism is presented. Smithsonian reporting on current volcanic activity dates back to 1968, with the Center for Short-Lived Phenomena (CSLP). The GVP is housed in the Department of Mineral Sciences, part of the National Museum of Natural History, on the National Mall in Washington, D.C. During the early stages of an eruption, ...

VEI 5
The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. The scale is open-ended with the largest eruptions in history given a magnitude of 8. A value of 0 is given for non-explosive eruptions, defined as less than of tephra ejected; and 8 representing a supervolcanic eruption that can eject (240 cubic miles) of tephra and have a cloud column height of over . The scale is logarithmic, with each interval on the scale representing a tenfold increase in observed ejecta criteria, with the exception of between VEI-0, VEI-1 and VEI-2. Classification With indices running from 0 to 8, the VEI associated with an eruption is dependent on how much volcanic material ...

Indonesian National Board For Disaster Management
The National Agency for Disaster Countermeasure (), abbreviated as BNPB, is the Indonesian board for natural disaster affairs. It was established in 2008 to replace the National Coordinating Board for Disaster Management ( or Bakornas PB). BNPB is directly responsible to the President of Indonesia and the chairman is directly appointed by the President. History On 20 August 1945, the Indonesian government established the Agency for Assisting Families of War Victims (; abbreviated as BPKKP) and its focus was to assist the war victims and their respective families during the Indonesian National Revolution. In 1966, the government established the advisory board of Central Natural Disaster Management (; abbreviated as BP2BAP) through the Presidential Decree Number 256 of 1966. The board was responsible to the Minister of Social Affairs. A year later, the Cabinet Presidium through Decree number 14/U/KEP/I/1967, established the National Coordination Team for Disaster Management (; abb ...

Seismologist
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies. It also includes studies of the environmental effects of earthquakes such as tsunamis; other seismic sources such as volcanoes, plate tectonics, glaciers, rivers, oceanic microseisms, and the atmosphere; and artificial processes such as explosions. Paleoseismology is a related field that uses geology to infer information regarding past earthquakes. A recording of Earth's motion as a function of time, created by a seismograph is called a seismogram. A seismologist is a scientist who works in basic or applied seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus () ...

Basaltic Andesite
Basaltic andesite is a volcanic rock that is intermediate in composition between basalt and andesite. It is composed predominantly of augite and plagioclase. Basaltic andesite can be found in volcanoes around the world, including in Central America and the Andes of South America. Description Basaltic andesite is a fine-grained (aphanitic) igneous rock that is moderately low in silica and low in alkali metal oxides. It is not separately defined in the QAPF classification, which is based on the relative percentages of quartz, alkali feldspar, plagioclase feldspar, and feldspathoids, but would fall in the basalt-andesite field. This corresponds to rock in which feldspathoid makes up less than 10% and quartz less than 20% of the total QAPF fraction, and in which at least 65% of the feldspar is plagioclase. Basaltic andesite would be further distinguished from basalt and andesite by a silica content between 52% and 57%. Although classification by mineral content is preferred by the ...

Mafic
A mafic mineral or rock is a silicate mineral or igneous rock rich in magnesium and iron. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. Common mafic rocks include basalt, diabase and gabbro. Mafic rocks often also contain calcium-rich varieties of plagioclase feldspar. Mafic materials can also be described as ferromagnesian. History The term ''mafic'' is a portmanteau of "magnesium" and "ferric" and was coined by Charles Whitman Cross, Joseph P. Iddings, Louis V. Pirsson, and Henry Stephens Washington in 1912. Cross' group had previously divided the major rock-forming minerals found in igneous rocks into ''salic'' minerals, such as quartz, feldspars, or feldspathoids, and ''femic'' minerals, such as olivine and pyroxene. However, micas and aluminium-rich amphiboles were excluded, while some calcium minerals containing little iron or magnesium, such as wollastonite or apatite, were included in t ...

Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Geology of Mars, Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) to porphyritic (coarse-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Tulamben
Tulamben is a small fishing village on the north-east coast of Bali. It is among the most popular dive sites on Bali since the wreck of the , a US Army Transport ship torpedoed by a Japanese submarine in 1942 lies just off shore. During high-season, up to 100 divers descend to the wreck each day. History The town's name is derived from the word ''batulambih'', which roughly translates as "many stones", a reference to the destructive eruptions by Mount Agung that have affected this part of Bali from time to time. The beach in Tulamben is not made of sand, but is entirely covered with fairly large, smooth stones. The modern name evolved over time, first to "Batulamben" and finally settling on the contraction Tulamben ("batu" means "stone" in Indonesian). Diving The best conditions for diving here are during October and November, when the weather is generally calm and during the start of southeast monsoon, which typically extends from May to July. In addition to a wide variety o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
USAT Liberty
USAT ''Liberty'' was a United States Army cargo ship torpedoed by in January 1942 and beached on the island of Bali, Indonesia. She had been built as a Design 1037 ship for the United States Shipping Board in World War I and had served in the United States Navy in that war as animal transport USS ''Liberty'' (ID-3461). She was also notable as the first ship constructed at Federal Shipbuilding, Kearny, New Jersey. In 1963 a volcanic eruption moved the ship off the beach, and ''Liberty''s wreck is now a popular dive site. World War I ''Liberty'' was launched on 19 June 1918 by the Federal Shipbuilding Company in Kearny, New Jersey, and acquired by the United States Navy on 7 October 1918 and commissioned the same day. Assigned to the Naval Overseas Transportation Service, ''Liberty'' departed the New York Navy Yard on 24 October 1918, arriving at Brest, France, with her cargo of horses on 8 November. Over the next 6 months, ''Liberty'' made two additional cruises from New Yo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Balinese People
The Balinese people (, ) are an Austronesian ethnic group native to the Indonesian island of Bali. The Balinese population of 4.2 million (1.7% of Indonesia's population) live mostly on the island of Bali, making up 89% of the island's population. There are also significant populations on the island of Lombok and in the easternmost regions of Java (e.g. the regency of Banyuwangi). The Balinese are distinctive amongst Indonesian ethnic groups for their adherence to Balinese Hinduism rather than Sunni Islam. Origins The Balinese originated from three periods of migration. The first waves of immigrants came from Java and Kalimantan in prehistoric times and were of Proto-Malay stock. The second wave of Balinese came slowly over the years from Java during the Hindu period. The third and final wave came from Java, between the 15th and 16th centuries, about the same time as the conversion to Islam in Java, causing aristocrats and peasants to flee to Bali after the collapse of the Ja ...
