Volcano Golovnina
kunashir island, Kuril Islands, Sakhalin region
Description:
This volcano is beautiful not by its size, but by multiple craters. The height of Golovnin is only about 500 meters. One of the calderas has a diameter of about five kilometers. Surrounded by high sides. There are four domes in the trough. One of them is occupied by the Boiling Lake. In another part of the caldera is located Lake Hot.
In the lake Boiling life beats the key, despite the fact that there are predominant chemical elements - hydrogen sulfide, sulfurous gases, hydrogen chloride and carbon dioxide. During the reactions, there is a constant sediment of sulfur, which is found everywhere in the crater. It is in the film of the reservoir, and in the sand on the shore, and even settles at the bottom. This does not harm small fish. They live perfectly in hot springs, mud boilers and combined cycle jets.
Another lake - Hot is also rich in wildlife. Its maximum depth reaches 60 meters. The total area of the reservoir is three square kilometers. In addition to fish in the lake there are also crustaceans.
