An ash cloud from a Chilean volcano continues to cause travel disruptions in South America, but also as far away as Australia and New Zealand.
In parts of Argentina the ash has forced the closure of roads and schools, leaving a grey blanket across a wide area.
Officials say the volcano’s latest eruptions are not as high as earlier ones, down from 12,000 to 5,000 metres. However, that doesn’t mean the effect has diminished, they say, warning that no one knows what the volcano will do in the short or medium term and what the effects will be.
The volcano erupted 10 days, spewing out a large cloud of ash that moved eastward. Flights have been disrupted in the region over safety fears.
The fine particles pose a danger to aircraft bodies and engines.
An ash cloud from a volcano in Iceland last year caused far worse disruption as it was spread from ground level right up to the upper atmosphere.
