How do you imagine the world's most powerful volcano eruption? Boiling-hot orange lava spilling over the slopes of a mountain and destroying everything in its path? Huge clouds of ash, blacking out the sky and wiping out all the life in nearby towns? Toxic gases that sneak into the smallest nooks? But do you know that you might not even notice this devastating event?

There are over 1 million underwater volcanoes on our planet. But as you may guess, it's very hard to explore and examine these underwater monsters. No wonder scientists almost missed the largest underwater volcano eruption of our time!
