PVMBG reported that white steam-and-gas plumes rose as high as 150 m above Kerinci’s summit and drifted NE during 25-26 November. Gray plumes of variable densities rose 100-500 m above the summit and drifted NE, E, and NW. At 0830 on 27 November a gray ash plume rose about 400 m above the summit and drifted E. The Aviation Color Code remained at Orange (the second highest level on a four-color scale). The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 3-km exclusion zone.

Geological Summary. Gunung Kerinci in central Sumatra forms Indonesia's highest volcano and is one of the most active in Sumatra. It is capped by an unvegetated young summit cone that was constructed NE of an older crater remnant. There is a deep 600-m-wide summit crater often partially filled by a small crater lake that lies on the NE crater floor, opposite the SW-rim summit. The massive 13 x 25 km wide volcano towers 2400-3300 m above surrounding plains and is elongated in a N-S direction. Frequently active, Kerinci has been the source of numerous moderate explosive eruptions since its first recorded eruption in 1838.
