AVO raised the Concern Color Code at Veniaminof from Green to Yellow on 4 January because around that time several small ash emissions from the volcano's intracaldera cone were observed on the Internet camera in Perryville. Ash emissions were visible starting around 0938, but may have been obscured by meteorological clouds in previous images. The discrete ash emissions were small, rose hundreds of meters above the cone, and dissipated as they drifted E. Read all- More about Veniaminof volcano

On 22 December, explosions at Santa María's Santiaguito lava-dome complex produced ash plumes to 700-1,300 m above the dome. Small collapses occurred from lava-flow fronts on the SW side of Caliente Dome. According to the Washington VAAC, ash plumes were visible on satellite imagery on several days during 22-27 December.
