2006 Pingtung Earthquake
The 2006 Hengchun earthquakes occurred on December 26 at 20:26 and 20:34 China Standard Time, 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 subduction, subducting beneath the EP along the line of the Ryukyu Trench, forming the Ryukyu arc, 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 much the earth shake ...

Focal Mechanism
The focal mechanism of an earthquake describes the Fault (geology)#Slip.2C heave.2C throw, deformation in the Hypocenter, source region that generates the seismic waves. In the case of a Fault (geology), fault-related event, it refers to the orientation of the fault plane that slipped, and the slip Euclidean vector, 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", 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 displayed gra ...

Sham Shui Po District
Sham Shui Po District is one of 18 districts of Hong Kong. It is the second poorest district by income 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, China. It also saw the birth of public housing in Hong Kong, as the government sought to resettle those displaced by Shek Kip Mei Fire, a devastating fire in its slums. Sham Shui Po also hosted a Refugees in Hong Kong#From Vietnam, Vietnamese refugee camp during the influx of migration in the aftermath of the Vietnam War in the 1970s.

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, a "reactor ''trip''" at pressurized water reactors and "EPIS" at a CANDU reactor. In many cases, a scram is part of the routine shutdown procedure which serves to test the emergency shutdown system. Etymology There is no definitive origin for the term. United States Nuclear Regulatory Commission historian Tom Wellock notes that '' scram'' is English-language slang for leaving quickly and urgently (as in scrambling to get away), and he cites this as the original and most likely accurate basis for the use of ''scram'' in the technical context. Scram is sometimes cited as being an acronym for safety control rod axe man or safety cut rope axe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Reactor
A nuclear reactor is a device used to initiate and control a Nuclear fission, fission nuclear chain reaction. They are used for Nuclear power, commercial electricity, nuclear marine propulsion, marine propulsion, Weapons-grade plutonium, weapons production and Research reactor, research. Fissile material, Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutron, neutrons and split, releasing energy and multiple neutrons, which can induce further fission. Reactors stabilize this, regulating Neutron absorber, neutron absorbers and neutron moderator, moderators in the core. Fuel efficiency is exceptionally high; Enriched uranium#Low-enriched uranium (LEU), low-enriched uranium is 120,000 times more energy dense than coal. Heat from nuclear fission is passed to a working fluid Nuclear reactor#By coolant, coolant. In commercial reactors, this drives Turbine, turbines and electrical generator shafts.

Maanshan Nuclear Power Plant
The Maanshan Nuclear Power Plant ( or 核三; ''Hésān'') was a nuclear power plant located near South Bay, Hengchun, Pingtung County, Taiwan. The plant was Taiwan's third nuclear power plant and second-largest in generation capacity. Its two reactors were commissioned in 1984 and 1985, respectively, and shut down upon the expiration of each reactor's license, in 2024 and 2025. Generation Each unit at Maanshan was 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 could 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 we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hengchun, Pingtung
Hengchun is a Township (Taiwan), 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 29,702 as of February 2024. 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.
