South American ash cloud causes major disruptions

Volcanic ash "is very abrasive for plane engines, and could result in very serious complications”.

Buenos Aires: The vast ash cloud spewing from Chile`s Puyehue volcano caused major disruption to South American air travel, grounding hundreds of flights and upsetting regional diplomacy.

All flights in and out of the Argentine capital were halted, as well as most arriving or departing the Uruguayan capital Montevideo, forcing President Jose Mujica to postpone a Buenos Aires meeting with his Argentine counterpart.

As the travel misery intensified, organisers were also forced to delay Friday`s first annual meeting in Buenos Aires of finance ministers from the Union of South American Nations (UNASUR) regional bloc. No new date was set.

"Humans make plans, but God has the final word," Mujica, the Uruguayan leader, said on his weekly radio program.

The volcano, which rumbled to life on Saturday for the first time since 1960, is high in the Andes mountains, 870 kilometres (540 miles) south of the Chilean capital Santiago, near the border with Argentina.

Winds have spread the ash across much of southern Argentina, threatening to hurt tourism at the start of the winter ski season, as well as into Uruguay and southern Brazil, where airlines suspended flights "at least" until Friday.

Chilean volcano monitors said Puyehue was belching ash columns that reached nearly 7.5 kilometres (4.6 miles) into the sky.

A Buenos Aires aviation official said the ash was some 9,000 meters (29,000 feet) above the Argentine capital, adding that planes generally fly at 10,000 meters (33,000 feet).

Volcanic ash "is very dangerous, very abrasive for plane engines, and could result in very serious complications”, warned Argentine Transportation Secretary Juan Pablo Schiavi.

At Jorge Newbery International Airport in Buenos Aires, some travellers were clearly beginning to despair, while others waited anxiously for loved ones.

"I`m waiting for my mother to arrive from Chile. She`s 90 years old and probably alone in Santiago," Ana Adelardi said.

One man, standing forlornly next to his wife and their baggage, said they were heading to Salta in northern Argentina for their first vacation.

"We`ve already paid for everything and our time is running out," he added.

The first flight cancellations came on Tuesday, but the resumption of many routes on Wednesday had raised hopes that things would return to normal. Officials on Thursday sounded a more pessimistic note.

Most air terminals in central and southern Argentina will remain closed "until there is a guarantee that they can operate safely”, read a government statement, as a fine coat of ash blanketed much of the Argentine capital.

Authorities in the Uruguayan capital Montevideo warned that visibility would be "significantly reduced" at least until early Friday.

"The current projection... is that the cloud of volcanic ash will be with us all day," Meteorology and Aeronautics Office director Laura Vanoli told local radio.

While ruling out any "significant effect on human health”, the Health Ministry advised "caution" from people with respiratory allergies, telling them to limit outdoor activities.

It warned of severe irritation, reversible airway obstruction and ocular mucosa, especially in people with chronic conditions like asthma, COPD (chronic obstructive pulmonary disease), bronchitis and conjunctivitis.

The bucolic Argentine resort town of Villa La Angostura, just 40 kilometres (25 miles) from the volcano, was buried under more than 20 centimetres (eight inches) of ash, enough to knock down power lines and clog water pipes.

Close to the Chilean border, in the town of El Rincon, pensioner Ruben Monsalve refused to leave his home.

"Every day I feel a bit of movement" from seismic activity, he said. "But why get scared if I`m inside my house?"

Most of his neighbours fled days ago.

The eruption forced the Argentine ski resort town Bariloche, located some 100 kilometres (62 miles) from the volcano, to declare a state of emergency and close its airport.

Nearby, police rescued 16 people, including park rangers, trainee park rangers and tourists from picturesque Nahuel Huapi Lake after they became trapped on Victoria Island by volcanic debris.
