1604 Quanzhou Earthquake
The 1604 Quanzhou earthquake was an extremely large seismic event that occurred in the Taiwan Strait, off the coast of Fujian Province, near Quanzhou during the Ming dynasty. According to modern-day calculations, the earthquake had a moment magnitude of 8.1 . It is unknown how many casualties resulted from the quake, but major damage was reported. Tectonic setting The coast of Fujian Province, along the Taiwan Strait, is a tectonically stable part of the Eurasian Plate, therefore experience relatively low seismic activity. The area forms part of the passive margin between the continental crust of the South China Craton and the oceanic crust of the South China Sea. Within the stable South China Craton, there are three zones of higher earthquake activity, one of which is the Southeast China Coast seismic zone running through Guangdong and Fujian. This zone follows the South China Maritime Fold Belt, which formed during a subduction event during the Late Jurassic to Early Cretaceous ...

Ming Dynasty
The Ming dynasty (), officially the Great Ming, was an Dynasties in Chinese history, imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol Empire, Mongol-led Yuan dynasty. The Ming dynasty was the last orthodox dynasty of China ruled by the Han Chinese, Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump state, rump regimes ruled by remnants of the House of Zhu, Ming imperial family—collectively called the Southern Ming—survived until 1662. The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the naval history of China, navy's dockyards in Nanjin ...

Strike-slip
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Defensive Wall
A defensive wall is a fortification usually used to protect a city, town or other settlement from potential aggressors. The walls can range from simple palisades or earthworks to extensive military fortifications with towers, bastions and gates for access to the city. From ancient to modern times, they were used to enclose settlements. Generally, these are referred to as city walls or town walls, although there were also walls, such as the Great Wall of China, Walls of Benin, Hadrian's Wall, Anastasian Wall, and the Atlantic Wall, which extended far beyond the borders of a city and were used to enclose regions or mark territorial boundaries. In mountainous terrain, defensive walls such as ''letzis'' were used in combination with castles to seal valleys from potential attack. Beyond their defensive utility, many walls also had important symbolic functions representing the status and independence of the communities they embraced. Existing ancient walls are almost always masonry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slump (geology)
A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a Grade_(slope), slope. Movement is characterized by sliding along a concave-upward or planar surface. Causes of slumping include Earthquake, earthquake shocks, thorough wetting, freezing and thawing, undercutting, and loading of a slope. Translational slumps occur when a detached landmass moves along a planar surface. Common planar surfaces of failure include joints or bedding planes, especially where a permeable layer overrides an impermeable surface. Block slumps are a type of translational slump in which one or more related block units move downslope as a relatively coherent mass. A rotational slump occurs when a slump block, composed of sediment or rock, slides along a concave-upward slip surface with rotation about an axis parallel to the slope. Rotational movement causes the original surface of the block to become less steep, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Seismic Intensity Scale
The China seismic intensity scale (CSIS) is a national standard in the People's Republic of China used to measure seismic intensity. Similar to EMS-92 on which CSIS drew reference, seismic impacts are classified into 12 degrees of intensity, or ''liedu'' (, literally "degrees of violence") in Roman numerals from I for insensible to XII for landscape reshaping. The scale was initially formalized by the China Earthquake Administration (CEA) in 1980, therefore often referred to by its original title as "China Seismic Intensity Scale (1980)". It was later revised, and adopted as a national standard, or Guobiao, series GB/T 17742-1999 by then National Quality and Technology Supervision Administration (noGeneral Administration of Quality Supervision, Inspection, and Quarantine of P.R.C. AQSIQ) in 1999. The standard was set for revision not long before the 2008 Sichuan earthquake. ''Liedu'' scale Unlike the magnitude scales that objectively estimate the released seismic energy, ''l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Foreshock
A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space. The designation of an earthquake as ''foreshock'', ''mainshock'' or aftershock is only possible after the full sequence of events has happened. Occurrence Foreshock activity has been detected for about 40% of all moderate to large earthquakes, and about 70% for events of M>7.0. They occur from a matter of minutes to days or even longer before the main shock; for example, the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events. Some great earthquakes (M>8.0) show no foreshock activity at all, such as the M8.6 1950 India–China earthquake. The increase in foreshock activity is difficult to quantify for individual earthquakes but becomes apparent when combining the results of many different events. From such combined observations, the increase before the mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
