Portals into the machinations of the Earth, volcanoes take many forms – and occur due to a range of underlying processes. Take a look at these spectacular examples to understand a little about their destructive power – and the reason why | National Geographic UK

Incredible footage of volcanic eruption of a dormant volcano in Ethiopia from a commercial plane. 🌋 The dormant giant exploded with a towering ash column, pyroclastic clouds, and volcanic lightning ripping through the plume like threads of white fire. The entire scene was illuminated by the rising sun… turning destruction into something surreal and almost otherworldly. A moment no one on that plane will ever forget and one the world has never seen until now. ✈️ | Otherworld Earth
