Wrath of Nature

Few sights in nature can compare to the sheer magnificence of a
volcano erupting in full flow.

But while scenes of molten lava are relatively commonplace, this
otherworldly picture of Chaiten Volcano in southern Chile shows a
truly spectacular, and devastating, volcanic phenomenon.

This astonishing picture shows the Chaiten volcano erupting
during storms in the middle of the night

As clouds of toxic ash and dust tower into the sky, they ionise
the air, generating an explosive electrical storm. Colossal forks
of lightning spark around the noxious plume as it spews from the
volcano's crater, creating an image of raw, terrifying energy -
as if the air itself were ablaze.

Now, the worst-case scenario is the collapse of the volcano
accompanied by a "pyroclastic flow" - a devastating
super-eruption of scorching dense gas and molten rock that would
roll down the mountainside at 100mph or faster, incinerating and
flattening all in its wake.

Thankfully, experts think this is unlikely at this stage.

Pyroclastic flows are also called nuees ardentes - or
"burning clouds" - and are probably the single most
destructive weapon in nature's armoury, capable of flattening
cities in seconds.

It was such a catastrophe that destroyed the Roman town of
Pompeii in AD79.

The 3,300 ft Chaiten Volcano, 800 miles south of the Chilean
capital Santiago, is erupting for the first time in thousands of
years, sending a plume of ash into the sky that stretches as far as
Argentina.

It is also spewing out chunks of lava and hot rock. Authorities
have already evacuated around 4,200 people from the town of
Chaiten, six miles from the volcano, but 300 civilians and troops
remain and are being evacuated now. Rescue is complicated by the
fact that southern Chile is fragmented by fjords and access is
often difficult.

The village of Chaiten, next to the volcano, was virtually
emptied in a massive evacuation

Winds carried the ash to other towns in the region and across
the Andes to Argentina

The authorities are also evacuating a second town, Futaleufu.
Some of Futaleufu's 1,000 or so residents had already crossed
into neighbouring Argentina, where some areas have been showered
with ash and where authorities last week closed schools and treated
some for breathing problems.

The ash is more than six inches (15 cm) thick in places, and has
contaminated water supplies.

Chile, which sits right on the Pacific's volcanic "ring
of fire", has the world's second most active string of
volcanoes behind Indonesia.
