During 5-18 August, seismicity at Kerinci was dominated by small explosion earthquakes. According to the Darwin VAAC, on 27 August at 1000 an ash plume was observed at a height of ~3.5 km a.s.l. drifting to the NW. The cloud was not visible on satellite imagery.
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.
