2024 Taiwan Earthquake
On 3 April 2024, at 07:58:11 Time in Taiwan, NST (23:58:11 Coordinated Universal Time, UTC on 2 April), a 7.4 earthquake struck south of Hualien City, Hualien County, Taiwan. At least 19 people were killed and over 1,100 were injured in the earthquake. It is the strongest earthquake in Taiwan since the 1999 Jiji earthquake, with three aftershocks above Mw 6.0. Tectonic setting Taiwan has a history of strong earthquakes. The island is located within a complex Convergent boundary, zone of convergence between the Philippine Sea plate and Eurasian plate. At the location of the earthquake, these plates converge at a rate of per year. To the south of Taiwan, oceanic crust of the Eurasian plate is subducting beneath the Philippine Sea plate creating an island arc, the Luzon Volcanic Arc, Luzon Arc. At Taiwan, the oceanic crust has all been subducted and the arc is colliding with continental crust of the Eurasian plate. To the north of Taiwan, the Philippine Sea plate is in contrast ...

Uranus Building
The Uranus Building ( zh, c=天王星大樓, p=Tiānwángxīng dàlóu) was a ten-story tower building in Hualien City, Hualien County, Taiwan that remained partially collapsed after the 2018 Hualien earthquake. The building was constructed in 1986 and houses shops and apartments. The building was again heavily damaged on 3 April 2024 during the 2024 Hualien earthquake, which left the building tilted over at a 25-degree angle. Demolition began on the building two days after the quake and completed after a two week period. It was one of two tower buildings that were rendered structurally leaning due to the earthquake, next to other damaged buildings including the National Hualien Girls' Senior High School.

Oceanic Crust
Oceanic crust is the uppermost layer of the oceanic portion of the tectonic plates. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic cumulates. The crust lies above the rigid uppermost layer of the mantle. The crust and the rigid upper mantle layer together constitute oceanic lithosphere. Oceanic crust is primarily composed of mafic rocks, or sima, which is rich in iron and magnesium. It is thinner than continental crust, or sial, generally less than 10 kilometers thick; however, it is denser, having a mean density of about 3.0 grams per cubic centimeter as opposed to continental crust which has a density of about 2.7 grams per cubic centimeter. The crust uppermost is the result of the cooling of magma derived from mantle material below the plate. The magma is injected into the spreading center, which consists mainly of a partly solidified crystal mush derive ... [...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 ...

TVBS
TVBS Media Inc. (), formerly Liann Yee Production Co., Ltd. () is a Taiwanese commercial television broadcasting company. It was originally established as a joint venture between Hong Kong television network TVB and Taiwanese network Era Television, Era Group, but TVB took over Era's shares in the company in 2005. Later, TVB sold all of its shares in the company to HTC Corporation Chairwoman Cher Wang. As of 2019, TVBS operates four domestic channels and one international channel: TVBS, the flagship channel; TVBS News, 24-hour news channel; TVBS Entertainment, which shows variety and drama series; TVBS E! (formerly TVB8), an alternative channel available on CHT MOD IPTV platform; and TVBS Asia, available outside Taiwan. History The company's flagship channel, TVBS, began its broadcast through satellite DTH and local cable systems on 28 September 1993. The name originally stood for "TVB Superchannel", while its Chinese name was ''Wuhsien Weihsing Tienshiht'ai'' (). It was origin ...

Taroko National Park
Taroko National Park () is one of the nine wonders in Taiwan and was named after the Taroko Gorge, the landmark gorge of the park carved by the Liwu River. The park spans Taichung Municipality, Nantou County, and Hualien County and is located in Xiulin Township, Hualien County, Taiwan. History This national park was originally established as the by the Governor-General of Taiwan on 12 December 1937 when Taiwan was part of the Empire of Japan. After the Empire of Japan's defeat in World War II, the Republic of China took over Taiwan in consequence. The ROC government subsequently abolished the park on 15 August 1945. It was not until 28 November 1986 that the park was reestablished. In 2002 it was named a potential World Heritage Site.https://twh.boch.gov.tw/taiwan/index.aspx?lang=en_us Taroko National Park covers an area of .

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Central Weather Administration
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 ...

Continental Crust
Continental crust is the layer of igneous, metamorphic, and sedimentary rocks that forms the geological continents and the areas of shallow seabed close to their shores, known as '' continental shelves''. This layer is sometimes called '' sial'' because its bulk composition is richer in aluminium silicates (Al-Si) and has a lower density compared to the oceanic crust, called '' sima'' which is richer in magnesium silicate (Mg-Si) minerals. Changes in seismic wave velocities have shown that at a certain depth (the Conrad discontinuity), there is a reasonably sharp contrast between the more felsic upper continental crust and the lower continental crust, which is more mafic in character. Most continental crust is dry land above sea level. However, 94% of the Zealandia continental crust region is submerged beneath the Pacific Ocean, with New Zealand constituting 93% of the above-water portion. Thickness and density The continental crust consists of various layers, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
