1999 Jiji Earthquake
The Chi-Chi earthquake (later also known as the Jiji earthquake) (), also known as 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 Tuesday, 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 government's performance in reacting to it was said by some commentators to ...

Time In Taiwan
National Standard Time is the official time zone in Taiwan defined by an UTC offset of +08:00. This standard is also known as Taipei Time () or Taiwan Time (). History The first time zone standard in Taiwan was enforced on 1 January 1896, the second year of Taiwan under Japanese rule. The standard was called with time offset of UTC+08:00, based on 120°E longitude. On 1 October 1937, the Western Standard Time zone was abolished and the , with time offset of UTC+09:00, was enforced in the entire country of Japan including Taiwan. This time was used until the end of the Second World War. On 21 September 1945, the Governor-General of Taiwan announced that the order issued in 1937 was revoked. Time Memorial Day was observed every 10 June from 1921 to 1941, which led to an increase in the observance of an official time. After the war's end, Taiwan was annexed to the five time zones system of the Republic of China and was classified in the "Chungyuan Standard Time" with time off ...

Kuomintang
The Kuomintang (KMT), also referred to as the Guomindang (GMD), the Nationalist Party of China (NPC) or the Chinese Nationalist Party (CNP), is a major political party in the Republic of China, initially on the Chinese mainland and in Taiwan after 1949. It was the sole party in China during the Republican Era from 1928 to 1949, when most of the Chinese mainland was under its control. The party retreated from the mainland to Taiwan on 7 December 1949, following its defeat in the Chinese Civil War. Chiang Kai-shek declared martial law and retained its authoritarian rule over Taiwan under the ''Dang Guo'' system until democratic reforms were enacted in the 1980s and full democratization in the 1990s. In Taiwanese politics, the KMT is the dominant party in the Pan-Blue Coalition and primarily competes with the rival Democratic Progressive Party (DPP). It is currently the largest opposition party in the Legislative Yuan. The current chairman is Eric Chu. The party originate ...

Yuanlin
Yuanlin (Hokkien POJ: ''Oân-lîm'') is a county-administered city in eastern Changhua County, Taiwan. It is the second largest settlement in the county, after the county seat of Changhua City. History The land around Yuanlin was cleared of trees and bushes, and fitted for cultivation since the Yongzheng era of the Qing dynasty (1723–1735). It was well developed about the 16th year of the Qianlong era. At first, people cut down the surrounding forests to build their houses. Gradually, only the round woodland was left, and the town was named (), meaning "the round woodland." Later the characters were changed to (Yuanlin). Yuanlin produces different kinds of fruits, and succade (fruit cooked in sugar syrup and encrusted with a sugar crystals) is one of its specialties. Republic of China After the handover of Taiwan from Japan to the Republic of China in 1945, Yuanlin was made the capital of the newly established Taichung County. In 1950, Changhua and Nantou were separated fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil Liquefaction
Soil liquefaction occurs when a cohesionless saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid. In soil mechanics, the term "liquefied" was first used by Allen Hazen in reference to the 1918 failure of the Calaveras Dam in California. He described the mechanism of flow liquefaction of the embankment dam as: The phenomenon is most often observed in saturated, loose (low density or uncompacted), sandy soils. This is because a loose sand has a tendency to compress when a load is applied. Dense sands, by contrast, tend to expand in volume or 'dilate'. If the soil is saturated by water, a condition that often exists when the soil is below the water table or sea level, then water fills the gaps between soil grains ('pore spaces'). In response to soil compressing, the po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Motion
Ground motion is the movement of the earth's surface from earthquakes or explosions. Ground motion is produced by seismic waves that are generated by sudden slip on a fault or sudden pressure at the explosive source and travel through the earth and along its surface. This can be due to natural events, such as earthquakes and volcanic eruptions, or human activities, such as the detonation of nuclear weapons. There are two main types of seismic waves: body waves and surface waves. Body waves travel through the interior of the earth, while surface waves travel along the earth's surface. Ground motion is typically caused by surface waves, which are the most destructive type of seismic waves. Ground motion is measured using a seismometer, a device that detects and records the movement of the earth's surface. Seismometers are used by seismologists to study earthquakes and other types of ground motion. The recordings produced by a seismometer are known as seismograms, and they can be use ...

Tsar Bomba
The Tsar Bomba () ( code name: ''Ivan'' or ''Vanya''), also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested. Overall, the Soviet physicist Andrei Sakharov oversaw the project at Arzamas-16, while the main work of design was by Sakharov, Viktor Adamsky, Yuri Babayev, Yuri Smirnov, and Yuri Trutnev. The project was ordered by Nikita Khrushchev in July 1961 as part of the Soviet resumption of nuclear testing after the Test Ban Moratorium, with the detonation timed to coincide with the 22nd Congress of the Communist Party of the Soviet Union. 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 of a nuclear device "of practically unlimited power". The bomb was dropped by parachute from a Tu-95V aircraft, and detonated autonomously above the cape Sukhoy Nos of Severny Island, N ...

Joule
The joule ( , ; symbol: J) is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. 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 In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule can also be defined by any of the following: * The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt. * The work required to produce one watt of power for one second, or one watt-second (W⋅s) (compare kilowatt-hour, which is 3.6 megajoules). This relationship can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Weather Bureau
The Central Weather Bureau (CWB; ) is the government meteorological research and forecasting institution of the Republic of China (Taiwan). In addition to meteorology, the Central Weather Bureau also makes astronomical observations, reports on sea conditions, and conducts research into seismology and provides earthquake reports. The Central Weather Bureau 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 Governor-General moved the headquarters to the present location occupied by the eventual successor agency of the Japanese "Taipei Observatory": the Central Weather Bureau. 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 In ...

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 Francis Richter and presented in his 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 logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

Sun Moon Lake
Sun Moon Lake (; Thao: ''Zintun'') is a lake in Yuchi Township, Nantou County, Taiwan. It is the largest body of water in Taiwan. The area around the lake is home to the Thao tribe, one of aboriginal tribes of Taiwan. Sun Moon Lake surrounds a tiny island called Lalu. The east side of the lake resembles a sun while the west side resembles a moon, hence the name. Sun Moon Lake is located above sea level. It is deep and has a surface area of approximately . The area surrounding the lake has many trails for hiking. While swimming in Sun Moon Lake is usually not permitted, there is an annual 3-km race called the ''Swimming Carnival of Sun Moon Lake'' held around the Mid-Autumn Festival each year. The Sun Moon Lake Swimming Carnival was launched in 1983 and is listed among the Top 50 Open Water Swims in Asia and the Top 100 Open Water Swims of the World. Everyone over 10 years old and with the ability to swim long distances can join, regardless of nationality. In recent years, ...

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. Surface damage Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in the magnitude 7.9 Denali earthquake of 2002 in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from . Continental earthquakes below are rare whereas in subduction zone earthquakes can originate at depths deeper than . Epicentral distance During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite s ...

Map Of 1999 Jiji Earthquake
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...
