1605 Guangdong Earthquake
The 1605 Qiongshan earthquake () occurred on 13 July (33rd year of reign of Emperor Wanli, May 28th in the Chinese lunar calendar) that struck Hainan and the adjacent Guangdong province in China with an estimated magnitude of 7.5 with a maximum felt intensity of X (''Extreme'') on the Modified Mercalli intensity scale. It caused widespread damage, including the 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.

Peak Ground Acceleration
Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an wikt:accelerogram, accelerogram at a site during a particular earthquake. Earthquake shaking generally occurs in all three directions. Therefore, PGA is often split into the horizontal and vertical components. Horizontal PGAs are generally larger than those in the vertical direction but this is not always true, especially close to large earthquakes. PGA is an important parameter (also known as an intensity measure) for earthquake engineering, The design basis earthquake ground motion (DBEGM) is often defined in terms of PGA. Unlike the Richter magnitude scale, Richter and Moment magnitude scale, moment magnitude scales, it is not a measure of the total seismic scales#Magnitude and intensity, energy (magnitude, or size) of an earthquake, but rather of how much the earth shake ...

Wanli Emperor
The Wanli Emperor (4 September 1563 – 18 August 1620), also known by his temple name as the Emperor Shenzong of Ming, personal name Zhu Yijun, art name Yuzhai, was the 14th List of emperors of the Ming dynasty, emperor of the Ming dynasty, reigning from 1572 to 1620. He succeeded his father, the Longqing Emperor. His reign of 48 years was the longest among all the Ming dynasty emperors. The Wanli Emperor ascended the throne at the age of nine. During the first ten years of his reign, the young emperor was assisted and effectively led by Grand Secretary Zhang Juzheng, a skilled administrator. With the support of the emperor's mother, Empress Dowager Xiaoding, Lady Li, and the imperial eunuchs led by Feng Bao, the country experienced economic and military prosperity, reaching a level of power not seen since the early 15th century. The emperor held great respect and appreciation for Zhang Juzheng. However, as time passed, various factions within the government openly opposed Zhang, ...

Hainan
Hainan is an island provinces of China, province and the southernmost province of China. It consists of the eponymous Hainan Island and various smaller islands in the South China Sea under the province's administration. The name literally means "South of the Sea". The province has a land area of , of which Hainan Island is and the rest is over 200 islands scattered across three archipelagos: Zhongsha Islands, Zhongsha, Xisha Islands, Xisha and Nansha Islands, Nansha. It was part of Guangdong from 1950 to 1988, after which it was made a province of its own and was designated as a special economic zones of China, special economic zone by Deng Xiaoping, as part of the Chinese economic reform program. The Han Han Chinese, Chinese population, who compose a majority of the population at 82%, speak a wide variety of languages including Standard Chinese, Hainanese, Hainam Min, Yue Chinese, Cantonese, Hakka Chinese, etc. Indigenous peoples such as the Hlai people, Hlai, a Kra–Dai l ...

Guangdong
) means "wide" or "vast", and has been associated with the region since the creation of Guang Prefecture in AD 226. The name "''Guang''" ultimately came from Guangxin ( zh, labels=no, first=t, t= , s=广信), an outpost established in Han dynasty near modern Wuzhou, whose name is a reference to an order by Emperor Wu of Han to "widely bestow favors and sow trust". Together, Guangdong and Guangxi are called ''Liangguang, Loeng gwong'' ( zh, labels=no, first=t, t=兩廣, s=两广 , p=liǎng guǎng) During the Song dynasty, the Two Guangs were formally separated as ''Guǎngnán Dōnglù'' ( zh, first=t, t=廣南東路, s=广南东路, l=East Circuit (administrative division), Circuit in Southern Guang , labels=no) and ''Guǎngnán Xīlù'' ( zh, first=t, t=廣南西路, s=广南西路, l=West Circuit (administrative division), Circuit in Southern Guang , labels=no), which became abbreviated as ''Guǎngdōng Lù'' ( zh, first=t, t=廣東路, s=广东路 , labels=no) and ''Guǎngxī Lù ...

Modified Mercalli Intensity Scale
The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake — an event occurring at greater or lesser depth. (The "" scale is widely used.) The MMI scale measures intensity of shaking, at any particular location, on the surface. It was developed from Giuseppe Mercalli's Mercalli intensity scale of 1902. While shaking experienced at the surface is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. They also differ in the depth at which they occur; deeper earthquakes have less interaction with the surface, their energy is spread throughout a larger volume, and the energy reaching the surface is spread across a larger area. Shaking intensity is localised. It generally diminishes with dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Earthquakes In Guangdong
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disasters In Hainan
A disaster is an event that causes serious harm to people, buildings, economies, or the environment, and the affected community cannot handle it alone. ''Natural disasters'' like avalanches, floods, earthquakes, and wildfires are caused by natural hazards. ''Human-made disasters'' like oil spills, terrorist attacks and power outages are caused by people. Nowadays, it is hard to separate natural and human-made disasters because human actions can make natural disasters worse. Climate change also affects how often disasters due to extreme weather hazards happen. Disasters usually hit people in developing countries harder than people in wealthy countries. Over 95% of deaths from disasters happen in low-income countries, and those countries lose a lot more money compared to richer countries. For example, the damage from natural disasters is 20 times greater in developing countries than in industrialized countries. This is because low-income countries often do not have well-built build ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
