Chi-Chi Earthquake
The Chi-Chi earthquake (later also known as the Jiji earthquake, 921 Earthquake, or the great earthquake of September 21), was a 7.3 ML or 7.7 Mw earthquake which occurred in Jiji (Chi-Chi), Nantou County, Taiwan on 21 September 1999 at 01:47:12 local time. 2,415 people were killed, 11,305 injured, and billion worth of damage was done. It is the second-deadliest earthquake in Taiwan's recorded history, after the 1935 Shinchiku-Taichū earthquake. Rescue groups from around the world joined local relief workers and the Taiwanese military in digging out survivors, clearing rubble, restoring essential services and distributing food and other aid to the more than 100,000 people made homeless by the quake. The disaster, dubbed the "Quake of the Century" by the local media, had a profound effect on the economy of the island and the consciousness of the people, and dissatisfaction with the government's performance in reacting to it was cited by a Taiwanese sociologist as ...

Dali District
Dali District ( zh, c=大里區, p=Dàlǐ Qū) is an inner city District (Taiwan), district in Taichung, Taiwan. Name The name "Dali" originates from ''Tai-li-khit'' ( zh, c=大里杙, poj=Tāi-lí-khi̍t), where ''Tai-li'' refers to the Hoanya aborigines and ''khit'' refers to a bamboo raft's toon. The word "khit" ( zh, c=:wiktionary:杙, 杙, poj=Khi̍t) means a tiny wooden post, referring to the time as a port city. History After the Retrocession of Taiwan, handover of Taiwan from Japan to the Republic of China (1912–1949), Republic of China in 1945, Dali was organized as a Township (Taiwan), rural township of Taichung County. On 1 November 1993, Dali was upgraded to a county-administered city due to its population. On 25 December 2010, Taichung County was merged with Taichung City and Dali was upgraded to a District (Taiwan), district of the Special municipality (Taiwan), city. Administrative divisions The current administrative divisions can be traced back to the 1920s u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tsar Bomba
The Tsar Bomba (code name: ''Ivan'' or ''Vanya''), also known by the alphanumerical designation "AN602", was a Thermonuclear weapon, thermonuclear aerial bomb, and by far the most powerful nuclear weapon ever created and tested. The Soviet physicist Andrei Sakharov oversaw the project at Arzamas-16, while the main work of design was by Sakharov, Viktor Adamsky, Yuri Babayev, , and Yuri Trutnev (scientist), Yuri Trutnev. The project was ordered by General Secretary of the Communist Party, First Secretary of the Communist Party Nikita Khrushchev in July 1961 as part of the Soviet resumption of nuclear testing after the Partial Nuclear Test Ban Treaty#Khrushchev and a moratorium: 1958–1961, Test Ban Moratorium, with the detonation timed to coincide with the 22nd Congress of the Communist Party of the Soviet Union (CPSU). Tested on 30 October 1961, the test verified new design principles for high-yield thermonuclear charges, allowing, as its final report put it, the design o ...

Joule
The joule ( , or ; symbol: J) is the unit of energy in the International System of Units (SI). In terms of SI base units, one joule corresponds to one kilogram- metre squared per second squared One joule is equal to the amount of work done when a force of one newton displaces a body through a distance of one metre in the direction of that force. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889). Definition According to the International Bureau of Weights and Measures the joule is defined as "the work done when the point of application of 1 MKS unit of force ewtonmoves a distance of 1 metre in the direction of the force." In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule is also equivalent to any of the following: * The work required to ...

Mainshock
In seismology, the mainshock is the largest earthquake in a sequence, sometimes preceded by one or more foreshocks, and almost always followed by many aftershocks. Foreshock A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space. The designation of an earthquake as ''foreshock'', ''mainshock'' or aftershock is only possible after the full sequence of events has happened. Aftershock In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to known laws. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes Doublet is a word de ...

Central Weather Bureau
The Central Weather Administration (CWA; ) is the government meteorological research and forecasting institution of Taiwan (the Republic of China). In addition to meteorology, the Central Weather Administration also makes astronomical observations, reports on sea conditions, and conducts research into seismology and provides earthquake reports. The Central Weather Administration is headquartered in Taipei City and is administered under the Ministry of Transportation and Communications. History While Taiwan was under Japanese rule, the government set up five weather monitoring stations on the island, located in Taipei, Taichung, Tainan, Hengchun, and Penghu. On 19 December 1897, the Taipei Observatory moved to the location presently occupied by the Central Weather Administration. In 1945 when the Kuomintang took control of Taiwan the various stations set up by the Japanese were incorporated into the new Taiwan Provincial Weather Institution, under the Chief Executive of Taiwan Pr ...

Richter Scale
The Richter scale (), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or .. Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses common logarithms simply to make the measurements mana ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mwg, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often use the term "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturatethat is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the United State ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun Moon Lake
Sun Moon Lake ( zh, t=, p=Rìyuè tán, poj= ; Thao language, Thao: ''Zintun'') is a lake in Yuchi, Nantou, Yuchi Township, Nantou County, Taiwan. It is the largest body of water in Taiwan. The area around the lake is home to the Thao people, one of Taiwan's indigenous peoples, indigenous ethnic groups. Sun Moon Lake surrounds a tiny island called Lalu Island, Lalu.

Epicenter
The epicenter (), epicentre, or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Determination The primary purpose of a seismometer is to locate the initiating points of earthquake epicenters. The secondary purpose, of determining the 'size' or magnitude must be calculated after the precise location is known. The earliest seismographs were designed to give a sense of the direction of the first motions from an earthquake. The Chinese frog seismograph would have dropped its ball in the general compass direction of the earthquake, assuming a strong positive pulse. We now know that first motions can be in almost any direction depending on the type of initiating rupture ( focal mechanism). The first refinement that allowed a more precise determination of the location was the use of a time scale. Instead of merely noting, or recording, the absolute motions of ...

Map Of 1999 Jiji Earthquake
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowing humans t ...
