Kaasuvedolliset
Kaasuvedolliset refers to a geological phenomenon where underground gas, often methane, escapes to the surface through natural fissures or disturbances in the ground. This can lead to the formation of gas vents, bubbles in water bodies, or even localized explosions if ignited. The gas typically originates from the decomposition of organic matter in soil and sediment layers, a process known as biogenic methanogenesis. In some cases, thermogenic methane from deeper geological formations can also contribute.
These occurrences are most commonly observed in areas with high organic content, such as wetlands, bogs, and
