Chile issues red alert over erupting volcano

Chile is issuing a red alert for a volcano on the border with Argentina that has become increasingly active.

The Copahue volcano in Argentina's Neuquen province started spewing ash and gas yesterday and officials issued a yellow and orange alert.

Chile's emergency office ONEMI raised the alert today after it registered seismic activity and a cloud of ash almost a mile (1.5 kms) high in the Biobio region .
