Chile volcano Calbuco quietens yet stays shaky.

The Chilean authorities have warned of further eruptions at the Calbuco volcano in southern Chile, which erupted twice last week.

During a lull in its activity, most airports in Chile and neighbouring Argentina reopened.They were closed because of the tons of fine volcanic ash thrown into the atmosphere.More than 6,000 people living close to the volcano have been evacuated.Scientists say they are also concerned that rain expected to fall in the next few days could mix with the ash to form dangerous mudslides.
