PVMBG reported that the eruption at Kerinci was ongoing during 1-7 February. An eruptive event was recorded at 0230 on 3 February but was not visually confirmed. White-and-gray ash plumes were visible later that day rising 100 m above the summit and drifting NE and E. At 0646 on 4 February a gray-to-brown ash plume rose 200 m and drifted E and SE. At 0722 on 5 February a dense brown ash plume rose 200 m and drifted NE and E. White-and-brown emissions rose as high as 150 m on 7 February. 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.
