PVMBG reported that the eruption at Kerinci was ongoing during 8-14 February. Ash plumes were visible on most days, though weather conditions prevented views towards the end of the week. At 0724 on 8 February a gray ash plum rose 150 m above the summit and drifted E. Gray-to-brown ash plumes rose 150 m and drifted NE that same day. White-and-gray ash plumes rose 150 m and drifted NE during 9-10 February. At 1740 on 10 February a dense gray ash plume rose around 100 m and drifted E, and on 14 February white-and-brown ash plumes rose 200 m and drifted NE. The Alert Level remained at 2 (on a scale of 1-4) and the public was reminded to stay 3 km away from the crater.
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.
