Spectacular: A time-lapse photo shows lightning bolts striking around the Puyehue-Cordon Caulle volcanic chain in PatagoniaFlames reach up to the heavens as lightening 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.
Nature's force: Lightning and volcanic fire is seen amid and underneath a towering cloud of ash. Puyehue volcano erupted for the first time in half a century on June 4
Incredible lighting bolts strike around the plume of volcanic ash and smoke
The dramatic scenes above the volcano makes an incredible cloud formation as smoke rises several miles into the airThe eruption in the Puyehue-Cordon Caulle volcanic chain, about 575 miles south of the capital, Santiago, also prompted authorities to close a busy border crossing into Argentina.
It was not immediately clear which of the chain's four volcanoes had erupted because of ash cover and weather conditions. The chain last saw a major eruption in 1960.
Local media said the smell of sulphur hung in the air and there was constant seismic activity.
'The Cordon Caulle (volcanic range) has entered an eruptive process, with an explosion resulting in a 10-kilometre-high gas column,' the state emergency office ONEMI said.

This development is the latest volcanic activity to affect the country. Three years ago, Chile's Chaiten volcano erupted spectacularly for the first time in thousands of years, spewing molten rock and a vast cloud of ash that reached the stratosphere and was visible from space.
It also drifted over neighbouring Argentina, coating towns. Chile's Llaima volcano, one of South America's most active, also erupted that year and again in 2009.
Chile's chain of about 2,000 volcanoes is the world's second largest after Indonesia. Some 50 to 60 are on record as having erupted, and 500 are potentially active.

One could be forgiven for thinking this was a wintry scene covered in snow, but in fact it is all ash
It was the latest in a series of volcanic eruptions in Chile in recent years.
Chile's Chaiten volcano erupted spectacularly in 2008 for the first time in thousands of years, spewing molten rock and a vast cloud of ash that reached the stratosphere.
The ash also swelled a nearby river and ravaged a nearby town of the same name.

Smiling lightning: As molten rock and gases are ejected from the core of the volcano below, what appears to be a 'have a nice day' face is formed from the electrically charged air
Protection: One man wears a gas mask to avoid breathing in ash
