The deaths were caused by asphyxiation. The shock of such strange occurrences has raised many questions within the scientific community.

The main questions stand out: What are these events? What are there causes? Based on eyewitness accounts and biological testing, scientists have created the following scenario of Limnic eruptions. Carbon dioxide collects at the bottom of a lake over time.

The people and livestock were literally choked to death. What is the cause for such rare occurrences?
