Intermittent mild to moderate explosive activity has continued at Tavurvur during the past week. Ash explosions and semi-continuous ash venting produced plumes rising up to about 1 km and alternated with periods of calm steaming.

from the latest Smithsonian / USGS Weekly Volcanic Activity Report:
"RVO reported that during 23-24 January variable emissions at Rabaul mostly consisted of white vapor plumes, although following explosions gray plumes rose 600 m above the crater. Some roaring and rumbling noises were noted.
"Five explosions were detected between 06:56 and 08:59 on 24 January; these explosions produced light gray ash plumes that rose as high as 1 km above sea level. After the explosion at 06:56 white plumes also rose from the crater. All plumes drifted E and ESE. Several explosions were detected between 16:30 on 24 January and 02:32 on 25 January, although seismicity remained at a low level. White vapor plumes and occasional light gray ash plumes rose from the crater and drifted E and SE.

"About five explosions occurred between 19:47 on 26 January and 04:14 on 27 January, producing plumes that drifted ESE. An explosion at 10:00 on 27 January produced a dense, billowing, light gray ash plume that rose a few hundred meters above sea level and drifted ESE. Ash emissions continued until 15:00, followed by white vapor emissions. Six explosions were detected overnight, possibly generating ash plumes that drifted E and ESE.

"During the morning of 28 January white vapor plumes rose from the crater. At 10:03 an explosion produced a dense, billowing, gray ash plume; ash emissions continued from the next hour and then turned to white vapor. Two explosions occurred at 13:23 and 18:16, generating ash plumes and sub-continuous emissions for one hour and 15-20 minutes, respectively. Plumes again drifted E and ESE. White plumes rose from the crater afterwards through 29 January, but an explosion at 17:23 generated a dense, billowing ash plume followed by a short period of sub-continuous emissions.
