1957 Mongolia Earthquake
An earthquake occurred in southern Mongolia on December 4, 1957, measuring 7.8–8.1 and assigned XII (''Extreme'') on the Modified Mercalli intensity scale. Surface faulting was observed in the aftermath with peak vertical and horizontal scarp reaching . Because of the extremely sparse population in the area, this event, despite its magnitude, was not catastrophic. However, 30 people died and the towns of Dzun Bogd, Bayan-leg and Baruin Bogd were completely destroyed. Tectonic setting As the Indian Plate collides with the Eurasian Plate, the force of the collision causes deformation. A primary effect of this collision is the uplift of the Himalayas; however, deformation extends further. In Mongolia, escape tectonics created a network of active faults to support the strike-slip stresses. During this earthquake, two main faults sustained a rupture: the thrust Gurvan Bulag fault, and the related strike-slip Bogd fault. The Gurvan Bulag has a slip rate of /yr for the vertica ...

Mongolian People's Republic
The Mongolian People's Republic ( mn, Бүгд Найрамдах Монгол Ард Улс, БНМАУ; , ''BNMAU''; ) was a socialist state which existed from 1924 to 1992, located in the historical region of Outer Mongolia in East Asia. It was ruled by the Mongolian People's Party, Mongolian People's Revolutionary Party and maintained close links with the Soviet Union throughout its history. Geographically, it was bordered by China to its south and the Soviet Union (via the Russian Soviet Federative Socialist Republic, Russian SFSR) to its north. Until 1944, it also bordered the Tuvan People's Republic, a Soviet satellite state recognized only by Mongolia and the Soviet Union. History Formation From 1758 to 1911, the Mongols were ruled by the Manchu Qing dynasty. In the first decade of the 20th century, the Qing government began implementing the so-called Late Qing reforms, New Policies, aimed at a further integration of Outer Mongolia. Upset by the prospect of the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1905 Tsetserleg Earthquake
The 1905 Tsetserleg earthquake occurred in or near the Tsetserleg Sum of Khövsgöl Province in Mongolia on 9 July 1905. The earthquake has been estimated at 7.9 to 8.3 on the moment magnitude scale. Background The Tsetserleg earthquake is believed to be a strike-slip rupture of a branch of the Bolnai Fault, extending about 190 km. The fault displacement during the earthquake was greater than 5 m, and the duration is estimated at about one minute. However, this interpretation is contested; field surveys after the earthquake show a complex rupture not necessarily characteristic of a strike-slip mechanism. The Tsetserleg earthquake was followed two weeks later by the Bolnai earthquake, and is considered a part of the same general crustal movement. Damage There are few records of the immediate effects of the earthquake due to the remoteness of Mongolia in 1905. However, rockslides were reported in the nearby mountains, and supposedly "two lakes, each of eight acres in size, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
December 1957 Events In Asia
December is the twelfth and final month of the year in the Julian and Gregorian calendars and is also the last of seven months to have a length of 31 days. December got its name from the Latin word ''decem'' (meaning ten) because it was originally the tenth month of the year in the calendar of Romulus which began in March. The winter days following December were not included as part of any month. Later, the months of January and February were created out of the monthless period and added to the beginning of the calendar, but December retained its name.Macrobius, ''Saturnalia'', tr. Percival Vaughan Davies (New York: Columbia University Press, 1969), book I, chapters 12–13, pp. 89–95. In Ancient Rome, as one of the four Agonalia, this day in honour of Sol Indiges was held on December 11, as was Septimontium. Dies natalis (birthday) was held at the temple of Tellus on December 13, Consualia was held on December 15, Saturnalia was held December 17–23, Opiconsivia was ...
