JMA reported that eruptive activity at Suwanosejima's Ontake Crater continued during 2-9 September and crater incandescence was observed nightly in webcam images. The seismic network recorded 12 explosions and numerous eruptive events. Occasional rumbling and ashfall were reported at the Suwanosejima Branch Office in Toshima village (3.5 km SSW) on unspecified dates.
Wed, 11 Sep 2024, 14:00KVERT reported that during 1-6 September lava extrusion likely continued at Sheveluch's “300 years of RAS” dome on the SW flank of Old Sheveluch and at a new vent or dome that formed during the 17-18 August explosive events. Daily thermal anomalies over the domes were identified in satellite images. Explosive activity during 1-2 September generated ash plumes that rose as high as 8 km (26,200 ft) a.s.l. and drifted 1,050 km NE.

PVMBG reported that eruptive activity continued at Semeru during 4-10 September with multiple daily eruptive events recorded by the seismic network. White-and-gray ash plumes that were sometimes dense rose 300-600 m above the summit and drifted SW during 5, 7, and 9-10 September. Emissions were not observed on the other days.

Wed, 11 Sep 2024, 14:00INSIVUMEH reported ongoing eruptive activity at Santa Maria's Santiaguito lava-dome complex during 3-10 September with lava extrusion, block collapses, and avalanches at the Caliente dome complex. Effusion of blocky lava produced block avalanches on the dome's flanks and occasional short pyroclastic flows that descended multiple flanks; the deposits created promontories of unstable material near the top of the 2022 lava flow located in the Zanjón Seco and San Isidro drainages. Incandescence from avalanches of material at the dome as well as explosions was visible during dark hours.

IG-EPN reported that high levels of eruptive activity continued at Sangay during 3-10 September and the seismic network recorded 112-275 daily explosions. Gas-and-ash plumes were visible in webcam and/or satellite images on most days and rose 400-600 m above the summit and drifted mainly W, WSW, and SW. Weather conditions sometimes obscured views; emissions were not visible on 5 September.

PVMBG reported that eruptive activity at Lewotobi's Laki-laki volcano continued during 4-10 September mainly from a vent on the upper NW flank. Daily gray or white-and-gray ash plumes that were sometimes dense rose as high as 1.2 km above the summit and drifted SW, W, and NW; only white emissions were visible on 4 September. A webcam image from 0333 on 5 September captured an area of incandescence on the flank and possible lightning in the lower part of the plume.

Wed, 11 Sep 2024, 14:00PVMBG reported that activity at Ibu continued during 4-10 September with multiple eruptive events recorded daily. Daily gray or white-and-gray ash plumes that were sometimes dense generally rose as high as 1.5 km above the summit and drifted in multiple directions. At 1756 on 7 September a dense gray ash plume rose as high as 4 km above the crater rim and drifted W.

Wed, 11 Sep 2024, 14:00INSIVUMEH reported that eruptive activity continued at Fuego during 3-10 September. Daily explosions were recorded by the seismic network, averaging 3-10 per hour. The explosions generated gas-and-ash plumes that rose as high as 1.1 km above the crater rim and drifted as far as 30 km NW, W, and SW.

Wed, 11 Sep 2024, 14:00PVMBG reported that the eruption at Dukono was ongoing during 4-10 September. Gray-and-white ash plumes that were sometimes dense rose 100-1,200 m above the summit and drifted E, S, and W on most days; white plumes rose as high as 800 m above the summit and drifted E on 4 September. The Alert Level remained at Level 2 (on a scale of 1-4), and the public was warned to remain outside of the 3-km exclusion zone.
