The Copahue volcano in Argentina's Neuquen province and Chile's Biobio region began spewing ash and gas early on Saturday, but officials say it's still in an early eruption stage. Chile's Mining Minister Hernan de Solminihac says the volcano's smoke plume led Argentine emergency officials to issue a yellow alert and constantly monitor its activity in case of a full eruption.
