साइबेरिया के लेक Baikal में बर्फ के नीचे मीथेन गैस ज्वाला दिखी

On Lake Baikal in Siberia, Russia, a guide lit methane gas trapped beneath the winter ice, producing visible flames. The methane is released by bacteria living in the lakebed, which generate the gas as they break down organic material. In summer it escapes into the air, but in winter it accumulates under the ice in bubbles. When ignited, the trapped gas flares up, creating a dramatic display.
