1946 Chatkal Earthquake
On November 2 of 1946, west Kyrgyzstan (then the Kirghiz Soviet Socialist Republic in the Soviet Union) was struck by a magnitude 7.5-7.6 earthquake, the largest in the republic since 1911. The earthquake's hypocenter is probably located beneath the Tien Shan Mountains, near the border with Uzbekistan and north of Namangan. The earthquake had a maximum intensity of X (''Extreme'') on the Mercalli intensity scale, and IX on the MSK scale. This shock rocked the entire country and Tian Shan Range. Severe property damage was reported in its aftermath but the number of deaths and injuries remains unknown. It has been considered one of the most devastating earthquakes in Central Asia. Two days later, a magnitude 6.9 earthquake struck nearby Turkmenistan, killing 400 people. Tectonic setting The Talas-Fergana Fault is a massive 800-km-long intracontinental strike-slip fault running through the Tien Shan Mountains, the largest in Central Asia. It has produced several significant earthq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kyrgyzstan
Kyrgyzstan,, pronounced or the Kyrgyz Republic, is a landlocked country in Central Asia. Kyrgyzstan is bordered by Kazakhstan to the north, Uzbekistan to the west, Tajikistan to the south, and the People's Republic of China to the east. Its capital and largest city is Bishkek. Ethnic Kyrgyz make up the majority of the country's seven million people, followed by significant minorities of Uzbeks and Russians. The Kyrgyz language is closely related to other Turkic languages. Kyrgyzstan's history spans a variety of cultures and empires. Although geographically isolated by its highly mountainous terrain, Kyrgyzstan has been at the crossroads of several great civilizations as part of the Silk Road along with other commercial routes. Inhabited by a succession of tribes and clans, Kyrgyzstan has periodically fallen under larger domination. Turkic nomads, who trace their ancestry to many Turkic states. It was first established as the Yenisei Kyrgyz Khaganate later in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Earthquakes In 1946
This is a list of earthquakes in 1946. 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. Several great shocks affected the planet in 1946. The largest was one of the most significant in human terms. The quake itself was a magnitude 8.6 striking on April 1 in Alaska resulting in a tsunami mainly affecting Hawaii. The consequence of this apart from many deaths was the foundation of the Pacific Tsunami Warning Center. This organisation has helped to substantially reduce the death toll of tsunamis in the Pacific, although there have been a few exceptions, including the 2011 Japan event. Japan itself was heavily affected in 1946 by a large quake hitting in December, causing 1,362 deaths. The Dominican Republic was another n ...

Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a distance equal to the rupture length away from the fault plane. The pattern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tashkent, Uzbekistan
Tashkent (, uz, Toshkent, Тошкент/, ) (from russian: Ташкент), or Toshkent (; ), also historically known as Chach is the Capital city, capital and List of cities in Uzbekistan, largest city of Uzbekistan. It is the most populous city in Central Asia, with a population of 2,909,500 (2022). It is in northeastern Uzbekistan, near the border with Kazakhstan. Tashkent comes from the Turkic languages, Turkic ''tash'' and ''kent'', literally translated as "Stone City" or "City of Stones". Before Islamic influence started in the mid-8th century AD, Tashkent was influenced by the Sogdian people, Sogdian and Turkic people, Turkic cultures. After Genghis Khan destroyed it in 1219, it was rebuilt and profited from the Silk Road. From the 18th to the 19th century, the city became an Tashkent (1784), independent city-state, before being re-conquered by the Khanate of Kokand. In 1865, Tashkent fell to the Russian Empire; it became the capital of Russian Turkestan. In Soviet Unio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Rupture
In seismology, surface rupture (or ground rupture, or ground displacement) is the visible offset of the ground surface when an earthquake rupture along a fault affects the Earth's surface. Surface rupture is opposed by buried rupture, where there is no displacement at ground level. This is a major risk to any structure that is built across a fault zone that may be active, in addition to any risk from ground shaking. Surface rupture entails vertical or horizontal movement, on either side of a ruptured fault. Surface rupture can affect large areas of land. __TOC__ Lack of surface rupture Not every earthquake results in surface rupture, particularly for smaller and deeper earthquakes. In some cases, however, the lack of surface effects is because the fault that moved does not reach the surface. For example, the 1994 Northridge earthquake had a moment magnitude of 6.7, caused major damage in the Los Angeles area, occurred at below the Earth's surface, but did not cause surface ...

Quake Lake
Quake Lake (officially Earthquake Lake) is a lake in the western United States, on the Madison River in southwestern Montana. It was created after an earthquake struck on August 17, 1959, with 28 fatalities. Northwest of West Yellowstone, Quake Lake is in length with a maximum depth of . U.S. Route 287 follows the lake and offers glimpses of the effects of the earthquake and landslide, and a visitor center is just off the road. The lake is mostly within Gallatin National Forest. Earthquake The earthquake measured 7.5 on the Richter magnitude scale (revised by USGS to 7.3) and caused an 80-million ton landslide, which formed a landslide dam on the Madison River. The earthquake was the most powerful to hit the state of Montana in historic times. The landslide traveled down the north flank of Sheep Mountain, at an estimated , killing 28 people who were camping along the shores of Hebgen Lake and downstream along the Madison River. Upstream the faulting caused by the earthqua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naryn (river)
The Naryn ( ky, Нарын, uz, Norin) rises in the Tian Shan mountains in Kyrgyzstan, Central Asia, flowing west through the Fergana Valley into Uzbekistan. Here it merges with the Kara Darya (near Namangan) to form the Syr Darya. It is long (together with its upper course Chong-Naryn) and its basin area is . It has an annual flow of . The river contains many reservoirs which are important in the generation of hydroelectricity. The largest of these is the Toktogul Reservoir in Kyrgyzstan containing of water. Dams downstream of the Toktogul in Kyrgyzstan include: Kürpsay, Tash-Kömür, Shamaldy-Say and Üch-Korgon. Upstream of Toktogul in Kyrgyzstan is the Kambar-Ata-2 and At-Bashy Dams while the Kambar-Ata-1 Dam is in planning stages.

Rockfall
A rockfall or rock-fallWhittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984. . is a quantity/sheets of rock that has fallen freely from a cliff face. The term is also used for collapse of rock from roof or walls of mine or quarry workings. "A rockfall is a fragment of rock (a block) detached by sliding, toppling, or falling, that falls along a vertical or sub-vertical cliff, proceeds down slope by bouncing and flying along ballistic trajectories or by rolling on talus or debris slopes." Alternatively, a "rockfall is the natural downward motion of a detached block or series of blocks with a small volume involving free falling, bouncing, rolling, and sliding". The mode of failure differs from that of a rockslide. Causal mechanisms Favourable geology and climate are the principal causal mechanisms of rockfall, factors that include intact condition of the rock mass, discontinuities within the rockmass, weathering susceptibility, ground and surface water, ...
