A sculpture of the Chilean national hero Arturo Prat is seen covered with ash from Chaiten volcano, at Futaleufu public square, some 1,450 km (900 miles) south of Santiago, May 9, 2008. A towering plume of ash from an erupting volcano in Chile's remote Patagonia could rain down on the surrounding area and cause devastating damage, a volcano expert warned on Friday. [Agencies]
