Baikal is located in a rift zone, a deep crack in the Earth's crust which narrows at depths of several dozen kilometers.

130 dead seals washed up in Russia's Lake Baikal, and scientists have taken lake water samples and biopsies of the animals. Preliminary theories about the die-off did not suggest pollution is the reason.
