A limnic eruption, also known as a lake overturn, is an extremely rare type of natural hazard in which dissolved carbon dioxide (CO2) suddenly erupts from deep lake waters, forming a gas cloud capable of asphyxiating wildlife, livestock, and humans. Scientists believe earthquakes, volcanic activity, and other explosive events can serve as triggers for limnic eruptions as the rising CO2 ejects water from the lake.
