This 9th deepest lake in the world with otherworldly deep blue color is part of a park that serves as a live laboratory for learning evolution of a volcano, its process of expanding mounts, spewing lava, resulting explosion and eventual but gradual formation of this sensational lake. Important fact: Volcanic eruptions can cause massive upheavel of environment with potential to disrupt human life as evidenced by the demise of Neanderthals (our close cousins) from volcanic activity in Campania region (one possible explanation) |
