The Tunguska ( Russian Подкаменная Тунгуска , transcription Podkamennaja Tunguska ; also Mean Tunguska , Russian Средняя Тунгуска / Srednjaja Tunguska ) is an eastern or right tributary of Jenissei in the central Siberia . With the source river Katanga it is 1865 km long.

The Tunguska area is known to astronomers for the Tunguska event , when a large meteorite exploded in 1908 and knocked over 2000 km² of forest.

course

The Stony Tunguska arises on the northern flank of the Angara ridge . From there it initially flows in a predominantly north-westerly direction through the southern part of the Central Siberian Mountains . The 641 km long headwaters to the confluence of the Tetere 400 km north of Bratsk (about  245  m above sea level.  Ostsee ) named Katanga (Катанга). Finally, the Stony Tunguska flows north of the Yenisei ridge at about 27  m above sea level. Baltic Sea near the village of Podkamennaya Tunguska, a district of the Bor settlement on the far west bank of the Yenisei 4 km downstream , into the Yenisei .

The Lower Tunguska , which flows in a large arc parallel to the Stony Tunguska and only flows into the Yenisei 600 km further north, rises about 100 km southeast of the source area of ​​the Katanga .

Localities and Tunguska event

On the stony Tunguska is the place Wanawara , which became famous through the Tunguska event. On June 30, 1908 , 65 km northwest of the town, a huge pressure wave devastated around 2000 km² of forest, knocking millions of trees radially outwards. The pressure wave was probably triggered by the core of a small comet that exploded several kilometers above the ground when it fell into the earth's atmosphere.

Hydrography
