1976 Songpan–Pingwu Earthquake
The 1976 Songpan–Pingwu earthquake that struck Songpan and Pingwu counties in Sichuan, China consisted of three mainshocks on the 16th, 21st, and 23rd (UTC) of August. A 1984 report gave the magnitudes as 7.2, 6.7, and 7.2, respectively (scale not specified).. The magnitudes were subsequently recalculated as 6.7, 6.3, and 6.4 on the scale, and 7.0, 6.6, and 6.7 on the scale. These were preceded by an earthquake swarm lasting three years. During the period from August 16 to August 31 there were over 400 aftershocks of magnitude 3.0 or greater. Short term earthquake warning were issued 3 months before the earthquake. There were 38 dead in the four counties struck—Songpan, Pingwu, Maowen and Nanping. More than 5,000 houses collapsed and 2800 heads of livestock lost. The earthquake was felt as far as Gaotai, Gansu to the west, Kunming, Yunnan to the south, Hohhot, Inner Mongolia to the north, and Changsha, Hunan to the east; an area with a maximum radius of 1,150 kilometers (7 ...

Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, 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 (geometry), 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 geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

China Earthquake Administration
The China Earthquake Administration (CEA; ) is a public institution managed by the State Council at the deputy ministerial level in charge of national earthquake disaster reduction work. It is currently managed by the Ministry of Emergency Management. Some English text use the name Chinese Seismic Bureau (CSB). In older text, it was also referred to by its former name, National Earthquake Bureau (NEB) or National Seismic Bureau (NSB).

Ngawa Tibetan And Qiang Autonomous Prefecture
Ngawa Tibetan and Qiang Autonomous Prefecture, also known as Aba (; Qiang language, Qiang: ; zh, s=阿坝藏族羌族自治州, t=阿壩藏族羌族自治州), is an autonomous prefecture of northwestern Sichuan, bordering Gansu to the north and northeast and Qinghai to the northwest. Its seat is in Barkam, and it has an area of . The population was 895,200 by 2022. The county of Wenchuan in Ngawa is the site of the epicenter of the 2008 Sichuan earthquake, in which over 20,000 of its residents died and 40,000 were injured. History and names During the reign of Tibetan Empire, Tibet's king Trisong Detsen in the 8th century, the Gyalrong area was visited by the great translator Vairotsana. In 1410 Je Tsongkhapa's student Tshakho Ngawang Tapa established the first Tibetan Buddhism, Tibetan Buddhist Gelug school monastery in the area, called "Gyalrong". In contemporary history, most of Ngawa was under the 16th Administrative Prefecture of Szechwan (), which was established by t ...

Earthquakes In Sichuan
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Geophysical Research
The ''Journal of Geophysical Research'' is a peer-reviewed scientific journal. It is the flagship journal of the American Geophysical Union. It contains original research on the physical, chemical, and biological processes that contribute to the understanding of the Earth, Sun, and Solar System. It has seven sections: A (Space Physics), B (Solid Earth), C (Oceans), D (Atmospheres), E (Planets), F (Earth Surface), and G (Biogeosciences). All current and back issues are available online for subscribers. History The journal was originally founded under the name ''Terrestrial Magnetism'' by the American Geophysical Union's president Louis Agricola Bauer in 1896. It was renamed to ''Terrestrial Magnetism and Atmospheric Electricity'' in 1899 and in 1948 it acquired its current name. In 1980, three specialized sections were established: ''A: Space Physics'', ''B: Solid Earth'', and ''C: Oceans''. Subsequently, further sections have been added: ''D: Atmospheres'' in 1984, ''E: Planets' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Earthquakes In China
This is a list of earthquakes in China, part of the series of list of disasters in China by death toll, lists of disasters in China. Earthquakes in the loess plateau where residents lived in yaodong caves tended to have big casualties, including the 1303 Hongdong earthquake, 1303 Hongdong and 1920 Haiyuan earthquakes. The most recent earthquake with a death toll of more than a thousand was the 2010 Yushu earthquake, which killed 2,968. The collision of India with the rest of Asia has led to seismic activity throughout Western China, particularly in Tibet and the Yunnan, Xinjiang, Sichuan, Gansu and Qinghai provinces. However, these regions in comparison with Eastern China have a low population density. These areas also in general have poorer transport and building codes. Throughout China, poor building codes increases the damage and loss of life from earthquakes. The northern regions of Eastern China are not as seismically active as the western areas of the country, but earthqua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Earthquakes In 1976
This is a list of earthquakes in 1976. Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for some other reason. 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 main point of note from this year was the devastation seen across the globe from several catastrophic events. Several countries experienced their worst ever natural disasters. Chronologically, Guatemala in February suffered 23,000 deaths. Indonesia in June had an earthquake causing 6,000 deaths. China in July had officially 242,000 deaths from the 1976 Tangshan earthquake. This was the worst toll from an earthquake for over 400 years. Shortly afterwards the Philippines had 8,000 fatalities. Towards the year end Turkey had an event resulting in 5,000 deaths.

1976 Longling Earthquake
The 1976 Longling earthquake in Yunnan Province, People's Republic of China, was a doublet earthquake, with two main shocks striking just east of Longling at 12:23:20 and 14:00:22 UTC (20:23 and 22:00 local time). The magnitudes were estimated at 6.7 and 6.6, respectively, on the scale, and 6.9 and 7.0 on the scale; Chinese sources put these at 7.4 and 7.3 on the scale. The region is noted for the quantity and intensity of its earthquakes, and the complexity of its tectonics, which are closely related to the collision between the Indian and Eurasian tectonic plates. No one died in the Longling county town. Loss in the 9 counties in Baoshan, Lincang and Dehong were 98 deaths, 451 severe injuries and 1,991 light injuries. 420,000 buildings collapsed in an area of 1883 square kilometers.
