2006 Hengchun Earthquake
The 2006 Hengchun earthquakes occurred on December 26 at 20:26 and 20:34 local time off the southwest coast of Taiwan in the Luzon Strait, which connects the South China Sea with the Philippine Sea. The International Seismological Centre measured the shocks at 7.0 and 6.9 on the moment magnitude scale. The earthquakes not only caused casualties and building damage, but several submarine communications cables were cut, disrupting telecommunication services in various parts of Asia. Tectonic setting Taiwan lies in a zone of complex interaction between the Philippine Sea Plate (PSP) and the Eurasian Plate (EP). To the north, the PSP is subducting beneath the EP along the line of the Ryukyu Trench, forming the Ryukyu Volcanic Arc. To the south, in contrast, the EP is subducting beneath the PSP along the line of the Manila Trench, forming the Luzon Volcanic Arc. At its northern end the Luzon Arc is colliding with the continental margin of the Eurasian Plate as the thicker and more buoy ...

Peak Ground Acceleration
Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an wikt:accelerogram, accelerogram at a site during a particular earthquake. Earthquake shaking generally occurs in all three directions. Therefore, PGA is often split into the horizontal and vertical components. Horizontal PGAs are generally larger than those in the vertical direction but this is not always true, especially close to large earthquakes. PGA is an important parameter (also known as an intensity measure) for earthquake engineering, The design basis earthquake ground motion (DBEGM) is often defined in terms of PGA. Unlike the Richter magnitude scale, Richter and Moment magnitude scale, moment magnitude scales, it is not a measure of the total seismic scales#Magnitude and intensity, energy (magnitude, or size) of an earthquake, but rather of how hard the earth shake ...

Focal Mechanism
The focal mechanism of an earthquake describes the deformation in the source region that generates the seismic waves. In the case of a fault-related event it refers to the orientation of the fault plane that slipped and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms. The focal mechanism can be derived from observing the pattern of "first motions", that is, whether the first arriving P waves break up or down. This method was used before waveforms were recorded and analysed digitally and this method is still used for earthquakes too small for easy moment tensor solution. Focal mechanisms are now mainly derived using semi-automatic analysis of the recorded waveforms. Moment tensor solutions The moment tensor solution is typically displayed graphically using a so-called ''beachball'' diagram. The pattern of en ...

Sham Shui Po District
Sham Shui Po District is one of 18 districts of Hong Kong. It is the poorest district in Hong Kong, with a predominantly working-class population of 405,869 in 2016 and the lowest median household income of all districts. Sham Shui Po has long been home to poorer new immigrants from mainland China. It also saw the birth of public housing in Hong Kong, as the government sought to resettle those displaced by a devastating fire in its slums. Sham Shui Po also hosted a Vietnamese refugee camp during the influx of migration in the aftermath of the Vietnam War. The district covers the Shek Kip Mei, Sham Shui Po, Cheung Sha Wan, Lai Chi Kok, Kowloon Tsai, So Uk, , and Yau Yat Chuen areas of New Kowloon, and Stonecutters Island of Kowloon.

SCRAM
A scram or SCRAM is an emergency shutdown of a nuclear reactor effected by immediately terminating the fission reaction. It is also the name that is given to the manually operated kill switch that initiates the shutdown. In commercial reactor operations, this type of shutdown is often referred to as a "scram" at boiling water reactors (BWR), a "reactor ''trip''" at pressurized water reactors and at a CANDU reactor. In many cases, a scram is part of the routine shutdown procedure, which serves to test the emergency shutdown system. The etymology of the term is a matter of debate. United States Nuclear Regulatory Commission historian Tom Wellock notes that ''scram'' is English-language slang for leaving quickly and urgently, and cites this as the original and most likely accurate basis for the use of ''scram'' in the technical context. A persistent alternative explanation posits that ''scram'' is an acronym for "safety control rod axe man", which was supposedly coined by Enrico ...

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...

Taiwan Power Company
The Taiwan Power Company (, Taipower; ) is a state-owned electric power industry providing electricity to Taiwan and off-shore islands of the Republic of China. History Taipower was established on 1 May 1946. Its origins can be traced to 1919 when Taiwan Power was founded during Japanese colonial rule. In 1994 a measure which allowed independent power producers (IPP's) to provide up to 20 percent of Taiwan's electricity should have ended the monopoly. On 1 October 2012, Taipower allied with Taiwan Water Corporation to provide cross-agency integrated services called ''Water and Power Associated Service'' that accepts summary transactions between the two utilities. On 11 October 2012, the Economics Committee of the Legislative Yuan cut Taipower's budget for power purchases from IPP. In July 2015, the Executive Yuan approved the amendments to the Electricity Act which were proposed by the Ministry of Economic Affairs, which will divide Taipower into two separate business grou ...

Maanshan Nuclear Power Plant
The Maanshan Nuclear Power Plant ( or 核三; ''Hésān'') is a nuclear power plant located near South Bay, Hengchun, Pingtung County, Taiwan. The plant is Taiwan's third nuclear power plant and second-largest in generation capacity. The expected lifespan of this plant is 60 years. Generation Each unit at Maanshan is a three-loop Westinghouse PWR with three Westinghouse type F steam generators. Each steam generator has 5626 U-bend tubes made of thermally treated Inconel 600 alloy. The power plant can generate 15 TWh of electricity per year. Events 1985 On 7 July 1985 a turbine blade failure at Maanshan Unit 1 led to a fire and reactor trip. When the blades failed, the resulting turbine imbalance allowed hydrogen and seal oil to escape from the generator. It took approximately 2 hours for the fire to be extinguished, but no systems critical to safe operation and shutdown were affected. The subsequent repairs were so extensive that Unit 1 did not come back on-line for 11 months ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hengchun, Pingtung
Hengchun Township is a township located on the southern tip of the Hengchun Peninsula in Pingtung County, Taiwan. It is the southernmost township in Taiwan. Hengchun is also the only urban township in the southern part of Pingtung County. Hengchun has a land area of and has a population of 30,859 as of December 2014. The city of Hengchun is the entryway to Kenting National Park, the southernmost National Park in the country. With pristine beaches and a vibrant tourist industry, the Hengchun area often attracts more travelers than local residents. The city itself was once completely surrounded by a city wall; now about half of the wall remains intact, as well as the four city gates. On weekends, the streets of nearby Kenting are filled with cars and tour buses. The 2008 Taiwanese film '' Cape No. 7'', the top-grossing film in Taiwan's film history, features Hengchun.
