All times are local (unless otherwise noted)


PVMBG reported that at 0614 on 30 October a brownish-white ash emission from Kerinci rose around 800 m above the summit and drifted NE, E, and SE. Brownish ash emissions rose 800 m and drifted WSW at 1721 on 30 October and to 500 m and drifted ESE at 0543 on 1 November. An eruptive event at 0553 on 2 November generated a brown ash emission that rose 500 m and drifted ESE. During 3-5 November brown ash plumes rose 100-500 m. 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.

Geologic Background. 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.
