Chile volcano ash grounds flights in Argentina
Posted by Admin on June 7, 2011
Since airborne ash can severely damage jet engines, Aerolineas Argentinas and Austral, the country’s state-owned international and domestic airlines, canceled all flights within Argentina as well as to and from other countries until further notice.
At least six international carriers also suspended flights through Wednesday between Buenos Aires and cities in the United States, Europe and South America. Other carriers were expected to follow. Flights from Chile over Argentine territory also were suspended.
The capital’s usually bustling international and domestic airports were nearly deserted Tuesday, and aviation regulators met to decide whether and for how long to close them. Geologists in Chile have said the Cordon Caulle volcano could keep erupting for several weeks.
The closest major city to the volcano is San Carlos de Bariloche, just over the border in Argentina, where thick abrasive soot was coating slopes in a string of resorts that depend on the winter ski season, opening in less than two weeks. The plume then stretched northeast before curving east, dumping ash over Argentina’s vast ranchlands before reaching the capital.
“Given that even this morning the volcano continues to be active, the reopening of the airports isn’t expected until the conditions necessary for security can be guaranteed,” Argentina’s transportation department announced.
Transportation officials were meeting with representatives of Argentina’s meteorological service, civil aviation board and airport regulator to figure out where the ash cloud will move next and what to do about it, the statement said.
Despite the complications to air travel, the ash couldn’t be seen in the streets of downtown Buenos Aires by midday Tuesday.
But Jorge Echarran, who runs the emergency council of the surrounding Buenos Aires province, said in a local radio interview that “the cloud is already in the suburbs and is reaching the capital,” hovering at an altitude of between 16,400 feet (5,000 meters) and 22,970 feet (7,000 meters).
The ash cloud was blowing well to the south and away from Chile’s capital, Santiago, but at least four international carriers there canceled flights across Argentina to Buenos Aires, Brazil, Uruguay and Europe as a precaution.
Closer to the volcano, strong rains that began Monday night increased the danger of rivers getting clogged with ash and then overflowing in flash floods. Evacuations were expanding, with more than 4,000 people already fleeing their homes.
Vulcanologist Jorge Munoz of Chile’s National Geology and Mines Service said the eruption so far is considered to be moderate, but that could change. He said the volcano will likely begin to expel lava in the coming days, along with pyroclastic material that can turn waterways into avalanches of mud and rock that have the potential to destroy downstream communities.
