Ash plumes rose as high as 1 km and drifted NW, causing ashfall mainly in a narrow band between the E part of old Rabaul town (3-5 km NW) and Namanula Hill, and further downwind towards Nonga area. Malaguna No. 1 and other parts of Rabaul town were also affected. Most noises were associated with forceful emissions and were short in duration. Seismicity was high and dominated by ash-emission events.
