An aerial view shows the Yelcho river covered with ashes from Chaiten volcano near Chaiten town, located some 1220 km (760 miles) south of Santiago May 4, 2008. Covered in thick ash, the Patagonian community of Chaiten was a ghost town on Saturday as a volcano spewed ash a day after its first eruption in thousands of years forced nearly 4,500 people to flee.
