In the northeast of Ethiopia, in the Danakil Desert, the active volcano Erta to Alya in which crater it is possible to see the streams of the melted lava escaping from the center of the earth is bred. Because of constant activity as a result of which over a volcano surface continually there are puffs, the volcano Erta to Alya and received the name in translation into Russian meaning "The smoker a volcano".
Erta to Alya – a basalt panel board volcano, one of five volcanoes on our planet in which heart there is a lava lake. But only at Erta to Alya there are not one, but whole two such sites. Tectonic drawing on a surface of lava lakes of a volcano Erta to Alya constantly changes. Here it is possible to consider, how long the stiffened magma sites forming a thin crust, and absolutely fresh, easily destroyed islands. This process is followed by chaotic splashes in brightly red melted lava and emissions of the accumulated gas. On a chemical composition of magma Erta to Alya compare to the deep-water volcanoes located in a middle part of the ridge at an ocean floor. In both cases the low content in magma of silicon acid is observed.
In recent years the volcano became more unpredictable. If in 2004 the lake in a crater of a volcano turned into a tectonic stronghold, having held on in such state of nearly 20 months, in November, 2010 the volcano woke up with an unexpected force. Eruption was followed by pushes which considerably affected a condition of breaks in northeast Africa. Scientists watch closely changes of activity of a volcano as it is in the important seismic zone called by "the Afarsky triangle". Noticeable shifts of plates and increase in width of breaks can change significantly a map of our planet, in particular, to affect all continent of Africa.
