Try to imagine the volcano crater. Got it? And now see pictures of the crater Nyiragongo. This volcano is located in the heart of the Great Lakes region in Africa.
Just unreal photos. In the center of this crater is a lake of lava, which then goes to sleep, then come alive again. Down to it is dangerous without special equipment. Smoke and sulfur fumes can kill.
And the heat is just hellish - to survive without the protective clothing at the lake is unreal - burn in a literal sense.
The volcano erupted in 1977 and 2002 - the lava came "from the coast, completely wiping out much of the city of Goma in Congo.
