RVO reported that ash plumes from Rabaul caldera’s Tavurvur cone rose to altitudes of 1.2-1.7 km (3,900-5,600 ft) a.s.l. and drifted NW, W, SW, S, SE, and E during 6-11 February. Ashfall was reported everyday in areas downwind, including Matupit, Kokopo, and Rabaul Town, and surrounding areas. During 6-7 February, incandescence at the summit was noted and incandescent material was propelled from a vent on the inner E wall of the crater.
