Tunguska may refer to:
Siberia is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed part of the sovereign territory of Russia and its various predecessor states since the centuries-long conquest of Siberia, which began with the fall of the Khanate of Sibir in the late 16th century and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over 13.1 million square kilometres (5,100,000 sq mi), but home to only one-fifth of Russia's population. Novosibirsk and Omsk are the largest cities in the area.
The Tunguska event was a 3–5 megaton explosion that occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate, Russia, on the morning of 30 June 1908. The explosion over the sparsely populated East Siberian taiga flattened an estimated 80 million trees over an area of 2,150 km2 (830 sq mi) of forest, and eyewitness accounts suggest up to three people may have died. The explosion is generally attributed to a meteor air burst, the atmospheric explosion of a stony asteroid about 50–60 metres wide. The asteroid approached from the east-south-east, probably with a relatively high speed of about 27 km/s (60,000 mph). Though the incident is classified as an impact event, the object is thought to have exploded at an altitude of 5 to 10 kilometres rather than hitting the Earth's surface, leaving no impact crater.
The Angara is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is 1,849 kilometres (1,149 mi) long, and has a drainage basin of 1,039,000 square kilometres (401,000 sq mi). It was formerly known as the Lower or Nizhnyaya Angara. Below its junction with the Ilim, it was formerly known as the Upper Tunguska and, with the names reversed, as the Lower Tunguska.
The Yenisey, also romanised as Yenisei or Jenisej, is the fifth-longest river system in the world, and the largest to drain into the Arctic Ocean.
The Amur River or Heilong River is a perennial river in Northeast Asia, forming the natural border between the Russian Far East and Northeast China. The Amur proper is 2,824 km (1,755 mi) long, and has a drainage basin of 1,855,000 km2 (716,000 sq mi). If including its main stem tributary, the Argun, the Amur is 4,444 km (2,761 mi) long, making it the world's tenth longest river.
The early history of Siberia was greatly influenced by the sophisticated nomadic civilizations of the Scythians (Pazyryk) on the west of the Ural Mountains and Xiongnu (Noin-Ula) on the east of the Urals, both flourishing before the common era. The steppes of Siberia were occupied by a succession of nomadic peoples, including the Khitan people, various Turkic peoples, and the Mongol Empire. In the Late Middle Ages, Tibetan Buddhism spread into the areas south of Lake Baikal.
The Nizhnyaya Tunguska is a river in Siberia, Russia, that flows through the Irkutsk Oblast and the Krasnoyarsk Krai. The river is a right tributary of the Yenisey joining it at Turukhansk. The ice-free period on the Nizhnyaya Tunguska starts in mid-June and ends in the first half of October. The river forms the western limit of the Lena Plateau.
Podkamennaya Tunguska may refer to:
The Turukhan is a river in northern Krasnoyarsk Krai in Russia. It is a southeast-flowing left tributary of the Yenisey. The river is 639 kilometres (397 mi) long. The area of its basin is 35,800 square kilometres (13,800 sq mi). The Turukhan freezes up in October and stays under the ice until late May or the first half of June. Its main tributaries are the Usomchik, Bolshaya Bludnaya, Verkhnyaya Baikha and Nizhnyaya Baikha from the right and Makovskaya from the left. Its mouth is 20 kilometres (12 mi) downstream from Turukhansk, where the Lower Tunguska joins the Yenisei. The river is navigable for about 288 kilometres (179 mi) from its mouth to the settlement of Yanov Stan. It was part of the canoe route from the Gulf of Ob – Taz – Turukhan – Yenisey – Nizhnyaya Tunguska – Yakutsk. The uncompleted Salekhard–Igarka Railway from the Ob to the Yenisey was planned to cross the Turukhan at Yanov Stan.
Bam or BAM may refer to:
The Tunguska event was an explosion that occurred on 30 June 1908, in the Siberian region of Russia, possibly caused by a meteor air burst. The event has inspired much speculation and appears in various fictional works.
Lake Cheko is a small freshwater lake in Siberia, near the Podkamennaya Tunguska River, in what is now the Evenkiysky District of the Krasnoyarsk Krai.
Siberian River Routes were the main ways of communication in Russian Siberia before the 1730s, when roads began to be built. The rivers were also of primary importance in the process of Russian conquest and exploration of vast Siberian territories eastwards. Since the three great Siberian rivers, the Ob, the Yenisey, and the Lena all flow into the Arctic Ocean, the aim was to find parts or branches of these rivers that flow approximately east-west and find short portages between them. Since Siberia is relatively flat, portages were usually short. Despite resistance from the Siberian tribes, Russian Cossacks were able to expand from the Urals to the Pacific in only 57 years (1582-1639). These river routes were crucial in the first years of the Siberian fur trade as the furs were easier to transport over water than land. The rivers connected the major fur gathering centers and provided for relatively quick transport between them.
Demid Sofonovich Pyanda or, according to some sources, Panteley Demidovich Pyanda, also spelled Penda (Пенда) was among the first and most important Russian explorers of Siberia. According to few historical documents and later reconstructions based on them, Pyanda, in 1620–1623, while leading a party which was hunting for Siberian furs and buying them from the locals, became the first known Russian to ascend the Lower Tunguska River and reach the proximity of the Lena, one of the world's greatest rivers. According to later legendary accounts, collected a century after his journey, Pyanda allegedly discovered the Lena River, explored much of its length, and via the Angara River returned to the Yenisey, whence he came.
The Kochechum is a river in Siberia, Russia. It flows through the Syverma Plateau in Krasnoyarsk Krai. It is a right and most significant tributary of the Nizhnyaya Tunguska.
Tunguska Nature Reserve is a Russian 'zapovednik' located in the central part of the Central Siberian Plateau. As a result of a meteorite in 1908, more than 2,000 km2 of boreal forest was felled and burned. The taiga affected in the disaster area has been restored in the past 100 years. The reserve is situated in the Evenkiysky District of Krasnoyarsk Krai.
The Bakhta is a river in Krasnoyarsk Krai, Russia. It is a right hand tributary of the Yenisey.
The Bolshoy Pit is a river in Krasnoyarsk Krai, Russia. It is a right hand tributary of the Yenisey.
The Tunguska is a river in the Khabarovsk Krai in Russia. It is a left tributary of the Amur. It is formed at the confluence of the rivers Kur and Urmi. It flows into the Amur about 15 km north of the city Khabarovsk. The Tunguska is 86 kilometres (53 mi) long, and has a drainage basin of 30,200 square kilometres (11,700 sq mi).
The Pilyuda is a river in Irkutsk Oblast, Russia. It is a tributary of the Lena with a length of 105 kilometres (65 mi) and a drainage basin area of 1,760 square kilometres (680 sq mi).
