How can fire come out of lake ice in siberia?

Fire can emerge from lake ice in Siberia due to the presence of methane gas, which can accumulate in sediments beneath the ice. As organic matter decomposes, it produces methane, which can seep through fissures in the ice. If this gas ignites, often from natural sources like lightning or human activities, it can create flames that appear to "come out" of the ice. This phenomenon is particularly notable in areas with permafrost, where methane is more likely to be trapped and released.
