Sarez Lake
Sarez Lake (russian: Сарезское озеро; tg, Сарез кӯл, Sarez Kūl) is a lake in Rushon District of Gorno-Badakhshan province, Tajikistan. Length about , depth few hundred meters, water surface elevation about above sea level and volume of water is more than . The mountains around rise more than above the lake level. The lake formed in 1911, after a great earthquake, when the Murghab River (Tajikistan), Murghab River was blocked by a big landslide. Scientists believe that the landslide dam formed by the earthquake, known as the Usoi Dam, is unstable given local seismicity, and that the terrain below the lake is in danger of catastrophic flood if the dam were to fail during a future earthquake. The Usoi Dam wall survived a localised 7.2 magnitude earthquake, the 2015 Tajikistan earthquake, on the 7th December 2015 with no visible signs of deterioration. Shadau Lake is a small water body southwest of the Usoi Dam and west of Sarez Lake. Formation The format ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Usoi Dam
The Usoi Dam is a natural landslide dam along the Murghab River (Tajikistan), Murghab River in Tajikistan. At high, it is the tallest dam in the world, either natural or man-made. The dam was created on February 18, 1911, when the 7.4-Surface wave magnitude, Ms 1911 Sarez earthquake, Sarez earthquake caused a massive landslide that blocked the flow of the river. The dam is formed of approximately of rock dislodged from the steeply sloped river valley of the Murghab River, Murghab, which cuts from east to west through the high and rough Pamir Mountains. It is named after the village of Usoi, which was completely buried by the 1911 landslide. The dam rises to a height of from the original valley floor. The basin formed by Usoi Dam now holds Sarez Lake, a -long lake holding of water. Water does not flow over the top of the dam, which would quickly cause it to erode away; instead, water seeps out of the base of the dam at a rate which approximately matches the rate of inflow, mai ...

Lakes Of Tajikistan
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khorog
Khorugh ( tg, Хоруғ, ; russian: Хорог, translit=Khorog; ) is the capital of the Gorno-Badakhshan Autonomous Region (GBAO) in Tajikistan. It is also the capital of the Shughnon District of Gorno-Badakhshan. It has a population of 30,500 (2020 ). Khorugh is above sea level in the Pamir Mountains (ancient Mount Imeon) at the confluence of the rivers Ghunt and Panj. The city is bounded to the south (Nivodak) and to the north (Tem) by the deltas of the Shakhdara and Ghunt, respectively. The two rivers merge in the eastern part of the city flow through the city, dividing it almost evenly until its delta in the Panj, on the border with Afghanistan. Khorugh is known for its poplar trees that dominate the flora of the city. History Until the late 19th century, Khorugh was in an area disputed between the Emir of Bukhara, Shah of Afghanistan, Russia and Britain. The Russians emerged the winners of the region after The Great Game, which fixed the current northern border of A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Old Style
Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, this is the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. In England, Wales, Ireland and Britain's American colonies, there were two calendar changes, both in 1752. The first adjusted the start of a new year from Lady Day (25 March) to 1 January (which Scotland had done from 1600), while the second discarded the Julian calendar in favour of the Gregorian calendar, removing 11 days from the September 1752 calendar to do so.Spathaky, MikOld Style and New Style Dates and the change to the Gregorian Calendar "Before 1752, parish registers, in addition to a new year heading after 24th March showing, for example '1733', had another heading at the end of the following December indicating '1733/4'.

2015 Tajikistan Earthquake
On December 7, 2015, an earthquake measuring 7.2 on the moment magnitude scale struck Tajikistan west of Murghab at 07:50 UTC at a depth of . The earthquake was also felt in neighboring Xinjiang in China, India, Afghanistan, Pakistan and Kyrgyzstan. The earthquake was felt with intensities of MMI IV in Islamabad, Pakistan, MMI IV in New Delhi, India, MMI IV in Kashgar, China, MMI II in Dushanbe, Tajikistan, MMI II in Kabul, Afghanistan, MMI III in Tashkent, Uzbekistan, MMI III in Bishkek, Kyrgyzstan, and MMI II in Almaty, Kazakhstan. A truck driver and a policeman were killed while dozens more were injured and 500 homes destroyed. The epicentre of this quake was approximately distant from the epicentre of the M7.3 1911 Sarez earthquake which formed the Usoi Dam across the Murghab river.

Seismicity
Seismicity is a measure encompassing earthquake occurrences, mechanisms, and magnitude at a given geographical location. As such, it summarizes a region's seismic activity. The term was coined by Beno Gutenberg and Charles Francis Richter in 1941. Seismicity is studied by geophysicists. Calculation of seismicity Seismicity is quantitatively computed. Generally, the region under study is divided in equally sized areas defined by latitude and longitude, and the Earth's interior is divided into various depth intervals on account of Earth's layering: Up to depth, , and > . The usual formula to calculate seismicity is: S = \frac where : _i: is the energy of a single seismic event (i.e., earthquake); : _0: interval of latitude; : _0: interval of longitude : _0: interval of the hypocenter; : _0: interval of the time of the seismic event. : The result is seismicity as energy per cubic unit.

Landslide Dam
A landslide dam or barrier lake is the natural damming of a river by some kind of landslide, such as a debris flow, rock avalanche or volcanic eruption. If the damming landslide is caused by an earthquake, it may also be called a quake lake. Some landslide dams are as high as the largest existing artificial dam.Robert B. Jansen (1988) "Advanced Dam Engineering for Design, Construction, and Rehabilitation", Causes The major causes for landslide dams investigated by 1986 are landslides from excessive precipitation and earthquakes, which account for 84%. Volcanic eruptions account for a further 7% of dams. Other causes of landslides account for the remaining 9%. Consequences The water impounded by a landslide dam may create a dam reservoir (lake) that may last for a short time, to several thousand years. Because of their rather loose nature and absence of controlled spillway, landslide dams frequently fail catastrophically and lead to downstream flooding, often with high casualti ...
