PVMBG reported that at 1804 on 10 May a brown ash emission from Kerinci rose 700 m and drifted ESE. Seismic activity was characterized by continuous volcanic tremor and gas emissions. The Alert Level remained at 2 (on a scale of 1-4) with a 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.
