Tangshan in the context of "Kaiping Tramway"

The 1976 Tangshan earthquake (Chinese: 唐山大地震; pinyin: Tángshān dà dìzhèn; lit. 'Great Tangshan earthquake') was a M_w 7.6 earthquake that hit the region around Tangshan, Hebei, China, at 19:42:55 UTC on 27 July (03:42:55, 28 July local time). 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 count stated 242,469 deaths, while historians accepted at least 300,000 died, making it the deadliest earthquake in recorded history (excluding the famine deaths from the 1556 Shanxi earthquake) and one of the worst disasters in China by death toll.

Bohai Bay (simplified Chinese: 渤海湾; traditional Chinese: 渤海灣; pinyin: Bóhǎi Wān) is one of the three major bays of the Bohai Sea, the northwestern and innermost gulf of the Yellow Sea. It is bounded by the coastlines of eastern Hebei province (Tangshan and Cangzhou), Tianjin municipality and northern Shandong province (Binzhou and Dongying) south of the Daqing River estuary (which is an old mouth of Luan River in Laoting County) and north of the Yellow River estuary. It is the most southerly water in the Northern Hemisphere where sea ice can form.

The Bohai Bay is the drainage destination of the Hai River and 15 other rivers. Due to these rivers' muddy runoff, the bay used to be a highly silty water body, but extensive damming of the various river systems has greatly diminished siltage. Nevertheless, the Bohai Bay in effect concentrates the runoff of the whole eastern North China Plain, and the Bay is an intensely polluted body of water. Reduced silt deposition and sea level rise are causing problems with sea encroachment in some coastal areas.

Liaodong Bay is largest and longest of the three main bays of the Bohai Sea, the innermost gulf of the Yellow Sea. The other two bays are Laizhou Bay to the south and Bohai Bay to the southwest.

Although named after the Liaodong Peninsula (which forms its eastern shore), the bay is located directly south of the Liaoxi region, almost entirely west of the Liao River. It is bounded by the coastline of cities from southern Liaoning province (Dalian, Yingkou, Panjin, Jinzhou and Huludao) and eastern Hebei province (Qinhuangdao and Tangshan), between the Laotieshan Cape at Dalian's Lüshunkou District in the east, and the Daqing River estuary (which is an old southern mouth of Luan River) at Tangshan's Laoting County in the west. The bay is a source of ecological importance and exhibits rich biodiversity.

Laoting County (simplified Chinese: 乐亭县; traditional Chinese: 樂亭縣; pinyin: Làotíng Xiàn), often mispronounced as Leting County in accordance with the alternative frequently used Mandarin pronunciation, is a county in the northeast of Hebei province, People's Republic of China, facing the Bohai Sea to the east and south. It is under the administration of the prefecture-level city of Tangshan. The county spans an area of 1,308 square kilometres (505 sq mi), and, as of 2017, has a population of approximately 419,100.

Ninghe District (simplified Chinese: 宁河区; traditional Chinese: 寧河區; pinyin: Nínghé Qū; lit. 'Tranquil River'), formerly Ninghe County, is a district of the municipality of Tianjin, People's Republic of China, located in the rural northeast part of the municipality. Inside this district, there are three enclaves. Two belongs to neighbour Tangshan: Lutai Economic Development Zone and Hangu Administration Zone. The last one, the Qinghe Farm (zh), is administered by Beijing Municipal Administration of Prisons
