RVO reported that ash emissions increased at Rabaul on 3 March and were mainly brownish. Emissions again increased the next day, occurring almost every minute. Billowing brown ash clouds slowly rose from the crater then quickly dispersed to the SE. The emissions decreased to about every hour on 7 March.
Seismicity was very high during 4-6 March and then declined in the evening of 7 March. Three regional earthquakes felt during this period ranged in magnitude from 5.1-5.5, and occurred SSE from Rabaul offshore outside the Wide Bay area at depths ranging between 50 and 60 km. They were felt in Rabaul town with intensities of III-IV. Emissions were absent during 8-11 March.
Activity resumed on 12 March at 1108. An explosion ejected tephra and a gray-to-black billowing ash plume rose 300 m and drifted SE. The forcefulness and color lessened over at least the next 40 minutes; ash plumes rose 100 m, but were carried to 1 km with the wind. Seismicity remained low.
