Volcano watch
• Puyehue Cordon Caulle Volcano in Chile erupted on June 4, throwing up a cloud of ash more than six miles high. Winds pushed the ash plume eastward, causing flight cancellations and delays all over South America and then in Australia, New Zealand and South Africa. The cloud started its second pass over Chile in late June, triggering further airport closures.
The volcano is expected to remain active, with another large eruption possible.
