Ashfall from Rabaul Volcano in Papua New Guinea has closed Tokua airport, forcing the cancellation of six flights. East New Britain’s Civil Aviation Authority said ash had been falling on the runway since Wednesday night. The runway would be fully cleared if winds change direction or if there was heavy rainfall. Rabaul's crater has been continuously deflating, going down by eight metres since the 1970s. No new material is being formed. The current eruption is old magma from beneath the caldera.
