SERNAGEOMIN reported that explosions in the main crater of Llaima propelled incandescent material 200-500 m in the air during 8-13 February. Explosions occasionally alternated between N and S cones in the main crater. On 9 February, the Calbuco River was about 1 m higher than the normal level, likely due to melt water from the lava and glacier interaction. On 10 February, Strombolian eruptions from the main crater were observed during an overflight. The lava flows on the W flank were 2.5 km long and made channels in the ice tens of meters deep. Although visual observations were limited due to cloud cover, sulfur dioxide and steam plumes from lava interacting with ice during 10-14 and 17 February rose to altitudes of 4.1-6.1 km (13,500-20,000 ft) a.s.l. Plumes drifted SE on 11 February. Lava flows were 3 km long on 11 February. On 13 February, incandescence at the summit was noted.
