The Russians consider it their greatest natural wonder. Of the 2,700 species of fish that swim in Lake Baikal, as many as 60% are considered endemic species (they inhabit a geographically limited territory and cannot be found anywhere else in the world).
As many as 544 streams flow into the lake, some of which are rivers of various sizes, and some streams and other seasonal streams. Only one river flows out of it and it is called Angara.
About 2,000 small and large earthquakes occur here every year. Although most feel weak, there are also those, such as the earthquake of 1862, when 10 degrees were measured on the Richter scale. On that occasion, due to the earthquake, the lake swallowed about 200 square kilometers of land with about 1,300 inhabitants.
In some scientific circles, it is believed that, since its inception (25 million years ago), until today, Lake Baikal has been in constant expansion. This phenomenon, as they say, is due to the movement of tectonic plates, among others, the massive Siberian underground platform on the very edge of which the lake is located.
The water in the lake is completely renewed every 380 years. The area of Lake Baikal is equivalent to the area of the entire state of Belgium.
Fishermen, as well as the local population, who later contacted scientists and researchers, witnessed the frequent appearance of glowing balls, which could be seen above the surface of the lake. People who live in the vicinity of this, according to many characteristics, unreal lake, claim that it is the spirits of their ancestors, who still live in that area. Scientists, as usual, have a different explanation, which says that it is methane gas that comes out of underwater pockets, which are abundant in the lake itself, and, in contact with oxygen, ignites and shines.
