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 ...

Taipei
Taipei (), officially Taipei City, is the capital and a special municipality of the Republic of China (Taiwan). Located in Northern Taiwan, Taipei City is an enclave of the municipality of New Taipei City that sits about southwest of the northern port city of Keelung. Most of the city rests on the Taipei Basin, an ancient lakebed. The basin is bounded by the relatively narrow valleys of the Keelung and Xindian rivers, which join to form the Tamsui River along the city's western border. The city of Taipei is home to an estimated population of 2,646,204 (2019), forming the core part of the Taipei–Keelung metropolitan area, which includes the nearby cities of New Taipei and Keelung with a population of 7,047,559, the 40th most-populous urban area in the world—roughly one-third of Taiwanese citizens live in the metro district. The name "Taipei" can refer either to the whole metropolitan area or just the city itself. Taipei has been the seat of the ROC central governm ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can bl ...

Eurasian Plate
The Eurasian Plate is a tectonic plate that includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia), with the notable exceptions of the Indian subcontinent, the Arabian subcontinent and the area east of the Chersky Range in eastern Siberia. It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge. The eastern edge is a boundary with the North American Plate to the north and a boundary with the Philippine Sea Plate to the south and possibly with the Okhotsk Plate and the Amurian Plate. The southern edge is a boundary with the African Plate to the west, the Arabian Plate in the middle and the Indo-Australian Plate to the east. The western edge is a divergent boundary with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland. All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippine Plate
The Philippine Sea Plate or the Philippine Plate is a tectonic plate comprising oceanic lithosphere that lies beneath the Philippine Sea, to the east of the Philippines. Most segments of the Philippines, including northern Luzon, are part of the Philippine Mobile Belt, which is geologically and tectonically separate from the Philippine Sea Plate. The plate is bordered mostly by convergent boundaries:Smoczyk, G.M., Hayes, G.P., Hamburger, M.W., Benz, H.M., Villaseñor, Antonio, and Furlong, K.P., 2013Seismicity of the Earth 1900–2012 Philippine Sea Plate and vicinity U.S. Geological Survey Open-File Report 2010–1083-M, scale 1:10,000,000, ''https://dx.doi.org/10.3133/ofr20101083m''. To the north, the Philippine Sea Plate meets the Okhotsk Plate at the Nankai Trough. The Philippine Sea Plate, the Amurian Plate, and the Okhotsk Plate meet near Mount Fuji in Japan. The thickened crust of the Izu–Bonin–Mariana arc colliding with Japan constitutes the Izu Collision Zone. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huatung Valley
The Huadong Valley or Hualien–Taitung Valley (), also known as East Rift Valley or the Longitudinal Valley, is a long and narrow valley located between the Central Mountain Range and the Coastal Mountain Range. It is also recognized as a plain area which stretches for about 180 kilometers near the eastern coast of Taiwan, passes from Hualien City at the north to Taitung City at the south. It was called or simply Nakasendō during the era of Japanese rule. The valley is believed to be part of the northern terminus of the Philippine Mobile Belt, a complex collection of tectonic plate fragments and volcanic intrusions. There are three large river systems flowing through this valley, including the Hualien, Xiugulan and Beinan Rivers, all of which flow into the Pacific Ocean. The Huadong Highway, a section of Provincial Highway No. 9, runs the entire length of the valley from north to south.

List Of Earthquakes In 1972
This is a list of earthquakes in 1972. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. The death toll of just over 40,000 was dominated by 2 events. In April, an earthquake struck Iran resulting in 30,000 of the deaths. This was one of the worst disasters in Iranian history. Late in December, Managua, Nicaragua was severely affected by a fairly modest magnitude 6.3 event. The location however contributed to 10,000 deaths and major destruction to the city. Activity was around normal for the year with 16 events exceeding magnitude 7.0. The largest struck the Philippines in Decemb ...

List Of Earthquakes In Taiwan
Taiwan is in a seismically active zone, on the Pacific Ring of Fire, and at the western edge of the Philippine Sea Plate.Taiwan Yearbook 2005, p. 23 Geologists have identified 42 active faults on the island, but most of the earthquakes detected in Taiwan are due to the convergence of the Philippine Sea plate and the Eurasian Plate to the east of the island. Most of the earthquakes registered in Taiwan actually occur off the east coast and cause little damage, whereas smaller quakes beneath the island itself have historically proven more destructive. The first recorded earthquake in Taiwan was in 1624, the founding year of Dutch Formosa. Between 1901 and the year 2000 there were 91 major earthquakes in Taiwan, 48 of them resulting in loss of life. The most recent major earthquake was the 921 earthquake, which struck on 21 September 1999, and claimed 2,415 lives. Many modern buildings in Taiwan are constructed with earthquake safety in mind, including Taipei 101, which had to cope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1972 Earthquakes
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
