The effusive eruption at the volcano is slowly but surely intensifying, Andi Volcanist, our expedition leader and guide, reported from field observations.

More and more glowing lava blocks continue to detach from the lava dome within the Crater 1, spreading onto the western and eastern flank, and illuminating mostly the western segment of the edifice.
As seen in the attached image, an impressive insight allows us to observe also a glowing Crater 2 in the background, meaning two craters out of five are active now.

Karangetang volcano (Sangihe Islands) - Smithsonian / USGS Weekly Volcanic Activity Report for 15 February-21 February 2023 (New Activity / Unrest)
According to PVMBG the eruption at Karangetang's Main Crater (S crater) continued during 14-21 February. Multiple nighttime webcam images posted with daily reports showed three main incandescent lava flows of different lengths descending the S, SW, and W flanks; a webcam image from 2156 on 17 February possibly showed incandescent material descending the SE flank. Incandescent rocks dotted the upper flanks, possibly from ejected or collapsed material from the crater; the incandescence was often most intense at the summit. ... Read all
