Aerolíneas Argentinas, LAN and Austral canceled flights from Buenos Aires' Jorge Newbery Metropolitan (aka Aeroparque) and Ezeiza International airports after the ash cloud arrived in the city, and Spain's Iberia airline canceled three flights from Madrid to the Argentine capital, the Buenos Aires Herald reported. The latter flights were rerouted to Santiago, Chile.

The airlines had already canceled a string of morning flights but later called off flights until 5 pm with a warning more could follow, depending how the situation unfolds, the newspaper reported.

In a statement to the Argentine news agency Télam, Chile's LAN airline said it would not “operate its flights in Aeroparque and Ezeiza International Airport until conditions are favorable and compatible with the highest security standards of the company."

Ash from Puyehue's weekend eruption grounded flights earlier this week. Smoke and ash shot more than 6 miles into the the sky after the Puyehue-Cordon Caulle volcano complex in southern Chile erupted Saturday afternoon.

Authorities evacuated about 3,500 people from the area, the state emergency office said. Cities including Bariloche, San Martin de los Andes and others canceled school and public activities.

The Patagonia region in southern Argentina was the most affected by the ash,which piled as high as 30 centimeters (about 1 foot) on highways through Patagonia.

Chile is on the "Ring of Fire," an arc of volcanoes and fault lines circling the Pacific Basin that is prone to earthquakes and eruptions.
