1927 Gulang Earthquake
The 1927 Gulang earthquake occurred at 6:32 a.m. on 22 May (22:32 UTC on 21 May). This 7.6 magnitude event had an epicenter near Gulang, Gansu in the Republic of China. There were 40,912 deaths. It was felt up to 700 km (435 mi) away. Geology The continental collision between the Indian Plate and the Eurasian Plate has formed the Himalayas and the large uplifted area of the Tibetan Plateau. The northeastern part of Tibet is affected by the eastward lateral spreading of the Tibetan Plateau. This spreading is accommodated by a series of sinistral (left-lateral) strike-slip faults, including the Altyn Tagh, Haiuyan, Kunlun and Xianshuihe faults, combined with thrusting on the Longmenshan fault. The earthquake ruptured the complex thrust fault system in the Qilian Mountains transpressional zone, formed at a restraining bend on the Haiyuan fault. Another segment of the Haiyuan fault was responsible for the 1920 Haiyuan earthquake. Damage In the area of greatest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or ''window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular ''klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind thr ...

Surface Wave Magnitude
The surface wave magnitude (M_s) scale is one of the magnitude scales used in seismology to describe the size of an earthquake. It is based on measurements of Rayleigh surface waves that travel along the uppermost layers of the Earth. This magnitude scale is related to the local magnitude scale proposed by Charles Francis Richter in 1935, with modifications from both Richter and Beno Gutenberg throughout the 1940s and 1950s. It is currently used in People's Republic of China as a national standard (GB 17740-1999) for categorising earthquakes. Recorded magnitudes of earthquakes through the mid 20th century, commonly attributed to Richter, could be either M_s or M_L. Definition The formula to calculate surface wave magnitude is: :M_s = \log_\left(\frac\right)_ + \sigma(\Delta)\,, where A is the maximum particle displacement in surface waves (vector sum of the two horizontal displacements) in μm, T is the corresponding period in s (usually 20 2 seconds), Δ is the epi ...

Seismic Scales
Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are usually determined from measurements of an earthquake's seismic waves as recorded on a seismogram. Magnitude scales vary on what aspect of the seismic waves are measured and how they are measured. Different magnitude scales are necessary because of differences in earthquakes, the information available, and the purposes for which the magnitudes are used. Earthquake magnitude and ground-shaking intensity The Earth's crust is stressed by tectonic forces. When this stress becomes great enough to rupture the crust, or to overcome the friction that prevents one block of crust from slipping past another, energy is released, some of it in the form of various kinds of seismic waves that cause ground-shaking, o ...

Yongchang County
Yongchang County () is a county located in the southern half of the prefecture-level city of Jinchang in north-central Gansu province, China, bordering Qinghai to the south. It has been associated with the historical Liqian and Fanhe counties. The village of Zhelaizhai, located in Jiaojiazhuang township, has been the subject of international academic and media attention for its potential connection to Sino-Roman relations. History The ancient Northern Silk Road passes through Yongchang County; numerous Han envoys were sent west along this trackway, some parties exceeding 100 members, late in the first millennium BC. The Han dynasty sent one mission to Parthia, which was reciprocated around 100 BC: Roman emissaries were captured by the Chinese in 30 BC along the Silk Road at Yongchang. At various times during the 20th century and early 21st century, the county has entered the sight of media because some of the inhabitants of Jiaojiazhuang township's Liqian village () (Zhelaizh ...

Wuwei, Gansu
Wuwei () is a prefecture-level city in northwest central Gansu province. In the north it borders Inner Mongolia, in the southwest, Qinghai. Its central location between three western capitals, Lanzhou, Xining, and Yinchuan makes it an important business and transportation hub for the area. Because of its position along the Hexi Corridor, historically the only route from central China to western China and the rest of Central Asia, many major railroads and national highways pass through Wuwei. History In ancient times, Wuwei was called Liangzhou (—the name retained by today's Wuwei's central urban district) and is the eastern terminus of the Hexi Corridor. People began settling here about 5,000 years ago. It was a key link for the Northern Silk Road, and a number of important archaeological finds were uncovered from Wuwei, including ancient copper carts with stone animals. The motifs and types of objects in the Wuwei graves, as well as their earthenware, lacquer, and bronze co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monseigneur Theodor Buddenbrock Conducts Missionary Work In China 1927
Monseigneur (plural: Messeigneurs or Monseigneurs) is an honorific in the French language, abbreviated Mgr., Msgr. In English use it is a title before the name of a French prelate, a member of a royal family or other dignitary. Monsignor is both a title and an honorific in the Roman Catholic Church. In francophone countries, it is rendered ''Monseigneur'', and this spelling is also commonly encountered in Canadian English practice. In France, monsignori are not usually addressed as ''monseigneur'', but by the more common term ''monsieur l'abbé'', as are priests. History As early as the fourteenth century it was the custom to address persons high in rank or power with the title Monseigneur or Monsignore. Until the seventeenth century, French nobles demanded from their subjects and dependents the title of Monseigneur. In international intercourse two titles gradually won general recognition, "Monsieur" as the title of the eldest brother of the King of France (if not heir presump ...
