1303 Hongdong Earthquake
The 1303 Hongdong earthquake occurred in Yuan dynasty of the Mongol Empire, on September 25. The shock was estimated to have a moment magnitude of 7.6 and it had a maximum Mercalli intensity of XI (''Extreme''). This is one of the most fatal earthquakes in China, in turn making it one of the top disasters in China by death toll. Geology Because of the time period in which it struck, very little is known about the nature of the earthquake. However, its epicentre was almost certainly located somewhere in what is now Shanxi (山西) province, near the present-day towns of Hongdong (洪洞) and Zhaocheng (赵城). The earthquake likely occurred on the Taigu fault zone in Shanxi, and several scarps and uplifts of local faults were seen as evidence of this; the Taigu fault zone has not experienced any measurable activity since the 1303 earthquake. The magnitude was calculated by modern seismologists to be 8.0 on the moment magnitude scale, though it is impossible to say for s ...

14th-century Earthquakes
As a means of recording the passage of time, the 14th century was a century lasting from 1 January 1301 ( MCCCI), to 31 December 1400 (MCD). It is estimated that the century witnessed the death of more than 45 million lives from political and natural disasters in both Europe and the Mongol Empire. West Africa experienced economic growth and prosperity. In Europe, the Black Death claimed 25 million lives wiping out one third of the European population while the Kingdom of England and the Kingdom of France fought in the protracted Hundred Years' War after the death of Charles IV, King of France led to a claim to the French throne by Edward III, King of England. This period is considered the height of chivalry and marks the beginning of strong separate identities for both England and France as well as the foundation of the Italian Renaissance and Ottoman Empire. In Asia, Tamerlane (Timur), established the Timurid Empire, history's third largest empire to have been ever establis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquakes In China
This is a List of earthquakes in China, part of the series of lists of disasters in China. China has been the location of some of the most deadly earthquakes in history. The deadliest was the 1976 Tangshan earthquake with 300,000+ deaths. Earthquakes in the loess plateau where residents lived in yaodong caves tended to have big casualties, including the 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 2,698. 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 C ...

List Of Historical Earthquakes
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the beginning of the 20th century. As the events listed here occurred before routine instrumental recordings, they rely mainly on the analysis of written sources. There is often significant uncertainty in location and magnitude and sometimes date for each earthquake. The number of fatalities is also often highly uncertain, particularly for the older events. Pre-11th century 11th–18th centuries 19th century Source for all events with 'USGS' labelled as the source United States Geological Survey (USGS''Note: Magnitudes are generally estimations from intensity data.

Liquefaction
In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics. It occurs both naturally and artificially. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and the noble gases." Another is the conversion of solid coal into a liquid form usable as a substitute for liquid fuels. Geology In geology, soil liquefaction refers to the process by which water-saturated, unconsolidated sediments are transformed into a substance that acts like a liquid, often in an earthquake. Soil liquefaction was blamed for building collapses in the city of Palu, Indonesia in October 2018. In a related phenomenon, liquefaction of bulk materials in cargo ships may cause a dangerous shift in the load. Physics and chemistry In physics and chemistry, the phase tr ...

Subsidence
Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement. Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater; gradual compaction of sediments; withdrawal of fluid lava from beneath a solidified crust of rock; mining; pumping of subsurface fluids, such as groundwater or petroleum; or warping of the Earth's crust by tectonic forces. Subsidence resulting from tectonic deformation of the crust is known as tectonic subsidence and can create accommodation for sediments to accumulate and eventually lithify into sedimentary rock. Ground subsidence is of global concern to geologists, geotechnical engineers, surveyors, engineers, urban planners, landowners, and the public in general.National Research Council, 1991.

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1556 Shaanxi Earthquake
The 1556 Shaanxi earthquake (formerly romanized ''Shensi''), known in Chinese colloquially by its regnal year as "" ('' Jiājìng Dàdìzhèn'') or officially by its epicenter as "" ('' Huàxiàn Dìzhèn''), occurred in the early morning of 23 January 1556 in Huaxian, Shaanxi during the Ming dynasty. Most of the residents there lived in yaodongs—artificial caves in loess cliffs—which collapsed and buried alive those sleeping inside. Modern estimates put the direct deaths from the earthquake at over 100,000, while over 700,000 migrated away or died from famine and plagues, which summed up to a total loss of 830,000 people in Imperial records.颤抖的地球—地震科学' rembling Earth: On Seismology(2005).

Loess
Loess (, ; from german: Löss ) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loess or similar deposits. Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs. Properties Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non-stratified and often calcareous. Loess grains are angular, with little polishing or rounding, and composed of crystals of quartz, feldspar, mica and other minerals. Loess can be described as a rich, dust-like soil. Loess deposits may become very thick, mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linfen
Linfen is a prefecture-level city in the southwest of Shanxi province, China, bordering Shaanxi province to the west. It is situated along the banks of the Fen River. It has an area of and according to the 2020 Census, a population of 3,976,481 inhabitants of which 959,198 live in the built-up (or metro) area made up of Yaodu urban district. The GDP of Linfen ranked second in Shanxi Province. It was known as Pingyang () during the Spring and Autumn period. In 2006, the American Blacksmith Institute listed Linfen as one of the ten most polluted cities in the world. Prior to 1978, Linfen was famous for its spring water, greenery and rich agriculture and therefore nicknamed "The Modern Fruit and Flower Town". Since then it has been developing into a main industrial center for coal mining, which has significantly damaged the city's environment, air quality, farming, health and its previous status as a green village. Name Linfen is named for the Fen River. Its former names inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
