1830 Cixian Earthquake
The region of Zhili (modern day Hebei province) was struck by a major earthquake with an estimated magnitude of 7.5 or 7.4 on June 12, 1830. The epicentre was close to Cixian, which suffered the most severe damage. A total of 7,477 people died as a result of the earthquake. Tectonic setting Cixian lies close to the western edge of the North China Basin, a rift basin that formed during the Eocene. Since the Pliocene, the active tectonics have been dominated by right-lateral strike-slip faulting. The two largest and most active of the fault zones are the Sanhe–Laishui Fault and the Tangshan–Heijian–Cixian Fault. The latter fault has been associated with many major historical earthquakes, including the 1976 Tangshan earthquake and the 1966 Xingtai earthquakes. Earthquake Based on macroseismic data the earthquake had an estimated magnitude of 7.5 or 7.4 . The maximum perceived intensity reached X (''extreme'') on the Modified Mercalli scale. Surface rupture interpreted to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 Chin ...

Sandblow
Sand boils or sand volcanoes occur when water under pressure wells up through a bed of sand. The water looks like it is boiling up from the bed of sand, hence the name. Sand volcano A sand volcano or sand blow is a cone of sand formed by the ejection of sand onto a surface from a central point. The sand builds up as a cone with slopes at the sand's angle of repose. A crater is commonly seen at the summit. The cone looks like a small volcanic cone and can range in size from millimetres to metres in diameter. The process is often associated with soil liquefaction and the ejection of fluidized sand that can occur in water-saturated sediments during an earthquake. The New Madrid Seismic Zone exhibited many such features during the 1811–12 New Madrid earthquakes. Adjacent sand blows aligned in a row along a linear fracture within fine-grained surface sediments are just as common, and can still be seen in the New Madrid area. In the past few years, much effort has gone into the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
