Lake Kivu Incident and Mitigation

The video discusses the dangers of Lake Kivu, located between the Democratic Republic of the Congo and Rwanda, known for its potential to cause catastrophic limnic eruptions. These eruptions occur when CO2 and methane gases, dissolved under high pressure in deep lakes, are suddenly released, causing deadly gas clouds. Historical eruptions at Lake Nyos and Lake Manoun serve as warnings. Lake Kivu, with its massive gas reserves, poses a significant threat to the 2 million people living nearby. Current mitigation efforts are insufficient, and the video encourages viewers to learn more about the science behind these phenomena through Brilliant.org.
