All times are local (unless otherwise noted)
On 9 August a small explosion at Kerinci produced an ash cloud that rose 700 m above the summit. Workers in rice fields around the volcano heard a booming sound and VSI personnel saw the dark brown ash cloud drift to the NNE. During 30 July-12 August seismographs recorded 990 small explosion events. The volcano was at Alert Level 2.
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.
