More than 5,000 people were forced to flee their homes after Mount Ulawun, known to be one of the most hazardous volcanoes in the world, erupted in a remote part of Papua New Guinea’s West New Britain.
Satellite imagery showed the eruption plume reaching heights of between 8 and 9.3 miles (13 and 15 km).
The Darwin Volcanic Ash Advisory Centre (DVAAC) issued a threat warning to aviation to reroute around the cloud, which was above the cruising level of commercial airlines, and flights have been cancelled into nearby Hoskins Airport
