Amazing pictures: The lightning
storm that engulfed an erupting volcano
By MICHAEL HANLON 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 100 mph or
faster, incinerating and
flattening all in its wake. Thankfully, experts think this is
unlikely at this stage.
![]() ![]() The Chaiten volcano has triggered earth tremors and spewed ash two miles into the air ![]() Seen from space, Chaiten's ash plume streams across Argentina towards the Atlantic ![]() Locals wear masks to protect themselves from the all-pervasive ash near Futaleuf ![]() The gigantic plume of smoke from the volcano dominates the skyline 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 ![]() A local resident cycles through the ash as it settles across the town 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
