Volcanic Hazard Becomes Energy Source?

Lake Kivu in Rwanda is a potential volcanic hazard because an estimated 256 cubic kilometres of carbon dioxide and an estimated 65 cubic kilometres of methane sits on its bed. Th gas is currently held at the bottom under pressure from above. However, the water is reaching saturation point an underground volcano or earthquake could disturb forcing it to the surface and triggering explosions. To try and prevent an explosion and to produce energy the Rwandan government is planning to pump the gas to the surface and burn it to create electricity.
