1969 Yangjiang Earthquake
The 1969 Yangjiang earthquake occurred on 26 July, at 6:49 am, Beijing local time (25 July 22:49 UTC). It had a magnitude of 6.4 on the moment magnitude scale and a maximum perceived intensity of VIII (''Severe'') on the Mercalli intensity scale. It struck the city of Yangjiang, causing over 10,700 houses to collapse and severely damaging a further 36,000. The earthquake also caused landslides and sandblows observed along the coast and along some rivers in the area of Yangjiang. The earthquake was also felt in Hong Kong. There were an unconfirmed total of 3,000 deaths. Tectonic setting Guangdong Province lies in a tectonically stable part of China, which has relatively low seismicity. The area forms part of the passive margin between the continental crust of China and the oceanic crust of the northern part of the South China Sea. Within the stable South China Block, there are three zones of higher earthquake activity, one of which is the Southeast China Coast seismic zone ru ...

Yangjiang
Yangjiang (, ), alternately romanized as Yeungkong, is a prefecture-level city in southwestern Guangdong Province in the People's Republic of China. It borders Maoming to the west, Yunfu to the north, Jiangmen to the east, and looks out to the South China Sea to the south. The local dialect is the Gaoyang dialect, a branch of Yue Chinese. During the 2020 census, its population was 2,602,959 inhabitants of whom 1,292,987 lived in the built-up (''or metro'') and largely urbanized area comprising Jiangcheng District and Yangdong County. History Under the Qing, made up part of the commandery of Zhaoqing. It was later split off as a separate prefecture in its own right. Administration The prefecture-level city of Yangjiang administers 4 county-level divisions, including 2 districts, 1 county-level city and 1 counties.

Fault (geology)
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 ...
