SANTIAGO, Chile (AP) — Authorities downgraded the likelihood of a major eruption at the Calbuco volcano, although the mountain remained active Saturday and the ash clouds it already ejected caused cancelations of more airline flights. Officials urged people to keep using masks or handkerchiefs to prevent breathing in dust and they warned against drinking water from surface springs that could have been contaminated by falling volcanic ash. Interior Minister Rodrigo Penailillo, who visited the area around the volcano about 620 miles (1,000 kilometers) south of Chile's capital, said the government would compensate farmers for losses from the eruptions.
