NASA Earth Observatory Imagery: Chile's Chaiten Volcano Erupts
Fears volcanic ash is causing ecological disaster
Volcanic ash raining down from the Chilean volcano Chaiten may
cause long-term environmental damage and harm the health of people
and animals in Patagonia, scientists say.
Ash from the volcano, which started erupting in early May for the
first time in thousands of years, is made up of pulverised rock
containing all kinds of minerals.
It has spoiled lakes, rivers and lagoons, coated plants in a
dense layer of gray, and altered the sensitive habitat of animals
now struggling to survive. Satellite images show a white stripe
smeared across the southern part of South America.
