Tangshan, China
Tangshan () is a coastal, industrial prefecture-level city in the northeast of Hebei province. It is located in the eastern part of Hebei Province and the northeastern part of the North China Plain. It is located in the central area of the Bohai Rim and serves as the main traffic corridor to the Northeast. The city faces the Bohai Sea in the south, the Yan Mountains in the north, Qinhuangdao across the Luan River to the east, and Tianjin to the west. Much of the city's development is thanks to the industrialization, beginning in 1870, when Kailuan Group established coal mines in the region. It's the birthplace of China's first standard-gauge railway, the first railway plant, the first steam locomotive, and the first cement factory. It was hailed as China's "cradle of industrialization". Even today, Tangshan is a hub of steel, energy, chemical, and ceramics production. Ping opera, which originated from the city's Luanzhou county, is one of the five most popular Chinese operas. T ...

Prefecture-level City
A prefecture-level city () or prefectural city is an administrative division of the People's Republic of China (PRC), ranking below a province and above a county in China's administrative structure. During the Republican era, many of China's prefectural cities were designated as counties as the country's second level division below a province. From 1949 to 1983, the official term was a province-administrated city (Chinese: 省辖市). Prefectural level cities form the second level of the administrative structure (alongside prefectures, leagues and autonomous prefectures). Administrative chiefs (mayors) of prefectural level cities generally have the same rank as a division chief () of a national ministry. Since the 1980s, most former prefectures have been renamed into prefectural level cities. A prefectural level city is a "city" () and "prefecture" () that have been merged into one consolidated and unified jurisdiction. As such it is simultaneously a city, which is a munici ...

Northeast China
Northeast China or Northeastern China () is a geographical region of China, which is often referred to as "Manchuria" or "Inner Manchuria" by surrounding countries and the West. It usually corresponds specifically to the three provinces east of the Greater Khingan Range, namely Liaoning, Jilin, and Heilongjiang, but historically is meant to also encompass the four easternmost prefectures of Inner Mongolia west of the Greater Khingan. The heartland of the region is the Northeast China Plain, the largest plain in China, with an area over . It is separated from Russian Far East to the north by the Amur, Argun, and Ussuri rivers; from Korea to the south by the Yalu and Tumen Rivers; and from Inner Mongolia to the west by the Greater Khingan and parts of the Xiliao River. Due to the shrinking of its once-powerful industrial sector and decline of its economic growth and population, the region is often referred to as China's Rust Belt. As a result, a campaign named Northeast Area Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richter Magnitude Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

1976 Tangshan Earthquake
The 1976 Tangshan earthquake () was a 7.6 earthquake that hit the region around Tangshan, Hebei, China, at 3:42 a.m. on 28 July 1976. The maximum intensity of the earthquake was XI (''Extreme'') on the Mercalli scale. In minutes, 85 percent of the buildings in Tangshan collapsed or were rendered unusable, all services failed, and most of the highway and railway bridges collapsed or were seriously damaged. The official report claimed 242,769 deaths and 164,851 serious injuries in Tangshan, but when taken into account the missing, the injured who later died and the deaths in nearby Beijing and Tianjin, scholars accepted at least 300,000 died, making it the deadliest earthquake in China and among the top disasters in China by death toll. The earthquakes The Tangshan earthquake was composed of two main shocks. The first struck at 3:42:56 in the morning (local time), approximately 12 km under the southern part of Tangshan.. The was initially estimated at 8.1, subsequent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Standard-gauge Railway
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kailuan Group
The Kailuan (Group) Co., Ltd. () is a major Chinese coal mining company. Chinese Engineering and Mining Company was its predecessor. In 2009, Kailuan Group planned to build a coal reserve base on the northeast coast to store 50 million tonnes of the fossil fuel. As one of the world's largest coal consumer and producer, it has set up four to six coal reserve bases, each with a storage capacity of more than 20 million tonnes, in eastern Shandong province to help cope with future supply shocks.

Luan River
The Luan River (, formerly known as ''Lei Shui'', or ''Ru Shui'') is a river in China. River The river flows northwards from its source in the province of Hebei into the province of Inner Mongolia, and then flows southeast back into Hebei to its mouth on the Bohai Sea. The headstream is known as Shandian River. This part of the river flows near the ancient Mongol capital city of Shangdu. Another important settlement in this section is Duolun. From here, the river's course turns to the southeast. Its length is about 600 km. One subsidiary is the Yixun He, which runs through Hebei. During its course, the Luan also passes by the Great Wall. After Chengde, the river is navigable. The largest city along the river's course is Chengde.
