S. America rattled by volcano devastation

Add A volcano in southern Chile, some 600 miles south of Santiago, erupts for a second day on June 5, 2011, shooting out a cloud of ash six miles high. Residents evacuated from the Puyehue-Cordón Caulle volcano complex area, and there have been no injuries. UPI/Miguel Angel Bustos  

SANTIAGO, Chile, June 13 (UPI) -- Several Latin American countries in the path of volcanic ash unleashed from a Chilean Andean crater are facing critical shortages of water, agricultural collapse, disruptions in transportation and growing risks to human and animal health.
Toxic ash clouds, seen to be dispersing toward Australia, have dumped the powdery substance across vast swathes of territory in Chile, Argentina, Brazil and Uruguay.
Air travel over the weekend remained erratic, with dozens of passenger aircraft grounded across airports in the region.

The Puyehue-Cordon Caulle volcano range in southern Chile began erupting June 4.

The ski season in Patagonia also faced cancellations as volcanic ash affected airport operations at Bariloche, Argentina, and clogged waterways including a river that runs off the slopes of the volcano. Several thousand inhabitants of nearby towns and villages in Chile and Argentina remained displaced, though some were allowed to return to their damaged homes.
Argentina said it faced an agricultural emergency in its Patagonian region as the blanket of ash left thousands of farm animals without pasture or water.
An estimated 750,000 sheep have been affected in Argentina alone. Data from Brazil, Chile and Uruguay weren't immediately available.
Sergio Pena, an Argentine livestock director said sheep were among the worst affected animals in the area.
"Sheep not only have little to eat but the ash grinds their teeth, further complicating the situation," he said.
Pena said local Argentine agricultural business could look to a much lower wool yield as a result of the ash contamination. The Chubut region was previously hit by a drought that lasted four years and killed more than 1 million sheep.
In Chile, ash and rocks pouring into the Nilahue River raised the temperature to 113 degrees Fahrenheit and killed more than 4.5 million fish, leaving local communities destitute or in need of government help.
National Fishing Service Director Guillermo Rivera told El Mercurio newspaper that fish loss was a direct result of the hot volcanic ash and rocks choking the river. The La Tercera newspaper said the river looked like a "thick, vaporous torrent of chocolate."
Officials said the long-term effects for the marine life of the lakes and rivers of the area will hit hard the fishing industry and tourism.
"I've never seen the lake like this. It's a disaster," Eudulio Velasquez, a cattle rancher, told La Tercera.
"I fish here in the Lago Puyehue and the Rio Gol Gol but I don't know if I'll be able to fish here anymore. I think that all the salmon and trout species have been wiped out in the Gol Gol. It's a tragedy for all the native species," Velasquez said.
Infrastructural damage from the ash has added to disruptions. Ash, landslides and snow blocked the Cardinal Samore Pass between Argentina and Chile after one of the walls collapsed.
The trucking route along the Pino Hachado crossing in the Araucania region was also blocked with vehicles carrying cargo to and from Argentina, Brazil, Chile, Paraguay and Uruguay stranded in the border region.
