It showed massive, grey-to-black, ash columns billowing vigorously at moderate to high angles from Vulcan and Tavurvur cones on opposite sides of Rabaul harbour. The vents on both cones appear to be in the order of 200 m wide, with the Vulcan vent extending down most of its harbourside flank. The maximum height of the cloud was said to be about 20,000 metres, with blocks as big as cars and possibly houses falling into the harbour. Lava was also reported to be flowing from Vulcan towards the harbour. Black ash appeared to be falling over a wide area and views of parts of Rabaul town showed buildings and vegetation blanketed by ash. Most of the rest of New Britain island appeared to be unaffected. The Australian Broadcasting Corporation television news late last night (Monday) reported that it was not clear whether four or five vents were active. Two of the vents may be on the harbour floor. One vent is located just off the end of the airstrip and the comment was made that the airstrip may never be used again. Media reports are now emphasizing the need to shelter and feed the evacuees and international appeals have been launched by non-government aid agencies. The town and surrounding villages have been evacuated but police teams have been sent back to deal with suspected looters. Fears are also held for a man apparently trapped in his house close to one of the vents, with the house near collapse from the weight of ash. Mention was also made of old people and children possibly trapped behind during the evacuation. However, only two deaths have been reported so far.
