1.697°S, 101.264°E; summit elev. 3800 m
All times are local (unless otherwise noted)
The eruption at Kerinci was ongoing with brown or white-and-brown ash plumes rising as high as 200 m above the crater rim on most days during 20 December 2022-3 January 2023. The amplitude of continuous tremor increased during 28-29 December, suggesting increased fluid flow or rising magma. The Alert Level remained at 2 (on a scale of 1-4).
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.
