PVMBG reported that the eruption at Kerinci was ongoing during 22-28 February. Weather clouds often prevented visual observations of the volcano. White-and-gray ash plumes rose 50-150 m above the crater rim and drifted W and E on 26 February. The next day white-and-brown ash plumes rose as high as 150 m and drifted W. 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.
