Flames reach up to the heavens as lightning flashes criss-cross the sky. These extraordinary images show the full force of Mother Nature as a Chilean volcano erupts for the first time in 50 years. Ash has been thrown six miles up into the sky and the South American government has ordered the evacuation of thousands of residents. Winds fanned the ash toward neighbouring Argentina, darkening the sky in the ski resort city of San Carlos de Bariloche, in the centre of the country, and its airport has also been closed.
