LIMNIC ERUPTIONS

A limnic eruption occurs when a gas, usually CO2, suddenly erupts from deep lake water, posing the threat of suffocating wildlife, livestock and humans. Such an eruption may also cause tsunamis in the lake as the rising gas displaces water. Scientists believe landslides, volcanic activity, or explosions can trigger such an eruption. To date, only two limnic eruptions have been observed and recorded:
In 1984, in Cameroon, a limnic eruption in Lake Monoun caused the deaths of 37 nearby residents.
At nearby Lake Nyos in 1986 a much larger eruption killed between 1,700 and 1,800 people by asphyxiation.
TSUNAMIS
Tsunamis can be caused by undersea earthquakes as the one caused by the 2004 Indian Ocean Earthquake, or by landslides such as the one which occurred at Lituya Bay, Alaska.
The 2004 Indian Ocean Earthquake created the Boxing Day Tsunami.
On March 11, 2011, a tsunami occurred near Fukushima, Japan and spread through the Pacific.
