VOICED : Chile teme tercera erupcion del Calbuco

After two violent eruptions, authorities fear a third from the Calbuco volcano. Residents in Puerto Varas, 40 km away, witnessed the silent eruption, which sent smoke directly into the clear sky, creating a spectacular scene. A large fumarole in the morning worried locals in the tourist areas of southern Chile and Argentina. Experts clarified it wasn't a new eruption but didn't rule out future activity. Authorities established a 20 km exclusion zone and evacuated 4,500 people as a precaution.
