Source summary
WikipediaA 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. Lakes in which such activity occurs are referred to as limnically active lakes or exploding lakes. Some features of limnically active lakes include:
Investigations of the Lake Monoun and Lake Nyos casualties led scientists to classify limnic eruptions as a distinct type of hazard event, even though they can be indirectly linked to volcanic eruptions.
