All times are local (unless otherwise noted)
PVMBG reported that during 19-22 August brown emissions from Kerinci rose as high as 600 m above the summit and drifted W. Pilots reported that during 20-21 August ash plumes rose to 4-4.6 km (13,000-15,000 ft) a.s.l., or 150-770 m above the summit, and drifted NE and SW. 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.
