What causes Limnic explosion?
Limnic eruptions can occur for two reasons. If the water becomes completely saturated with dissolved gases, any additional CO2 or methane injected into the lake will be forced to bubble out of solution, rise and be released into the air.
What triggers limnic eruptions?
How can you prevent a limnic eruption?
Once the degassing fountains have ceased, they cannot restart spontaneously. This means CO2 will buildup again at Lake Nyos due to continued natural recharge of magmatic CO2, implying an ongoing risk of recurrence of limnic eruption. The best way to avoid this risk is to remove the bottom water artificially.
Why does Lake Kivu explode?
Instead, the dissolved gas accumulates in denser bottom layers, capped by a ‘cork’ of pressure from the waters above (see ‘Deep gas’). If the gases accumulate to such an extent that they form bubbles, these lakes can literally explode like a champagne bottle.
