This is one of the FAQ's from the link below...
Do any of the features beneath the lake relate to possible volcanic eruptions?
It is very unlikely. All active features are related to faults and hot water (hydrothermal) vents. Identified craters were formed by collapse or as a
result of old hydrothermal explosions. Many of the rocks beneath the lake are lava flows more than 100,000 years old.
