JMA reported that eruptive activity at Suwanosejima's Ontake Crater continued during 3-10 June and produced volcanic plumes that rose as high as 700 m above the crater rim. Crater incandescence was observed nightly in webcam images. No explosions were recorded.
Wed, 12 Jun 2024, 14:00KVERT reported that thermal anomalies over both the new and older lava domes at Sheveluch were identified in satellite images during 1-2 and 4-6 June; the domes were obscured by weather clouds on 31 May and 3 June. The Aviation Color Code remained at Orange (the third level on a four-color scale). Dates are based on UTC times; specific events are in local time where noted.

PVMBG reported that eruptive activity continued at Semeru. Continuous tiltmeter and GPS data showed that inflation was detected in May and seismic data showed that magma continued to rise to the surface. During 5-11 June white-and-gray ash plumes that were sometimes dense rose 300-800 m above the summit and drifted S and SW on all days except for 7 June.

Wed, 12 Jun 2024, 14:00In a special report issued on 10 June IG-EPN reported that the number and amplitude of explosions at Reventador had increased beginning on 21 March and remained elevated, based on seismic data. Additionally, during this period a slight increase in sulfur dioxide emissions was identified in satellite data. The daily explosion count peaked on 26 May and again on 9 June.

Wed, 12 Jun 2024, 14:00BPPTKG reported that the eruption at Merapi (on Java) continued during 31 May-6 June. Seismicity had decreased compared to the previous week. The SW lava dome produced 141 lava avalanches that traveled as far as 1.9 km down the upper part of the Bebeng drainage on the SW flank.

PVMBG reported that eruptive activity at Marapi (on Sumatra) was ongoing during 5-11 June. White gas-and-steam plumes rose 200-300 m above the summit and drifted in multiple directions during 5-6 and 8 June. White-and-gray ash plumes rose 300-750 m above the summit and drifted multiple directions during 7 and 9-10 June.

AVO reported that slow lava effusion in Great Sitkin's summit crater continued during 5-11 June. Seismicity was low with few daily small earthquakes. Slightly elevated surface temperatures at the summit were identified in satellite images during 4-6 June and diffuse steam emissions were visible in webcam images during 5-6 June.

Wed, 12 Jun 2024, 14:00KVERT reported that moderate explosive activity was ongoing at Ebeko during 30 May-6 June. According to volcanologists in Severo-Kurilsk (Paramushir Island, about 7 km E), explosions during 31 May and 1-2 June generated ash plumes that rose as high as 2 km (6,600 ft) a.s.l. and drifted SE and S.

PVMBG reported that the eruption at Dukono was ongoing during 5-11 June. Gray-and-white ash plumes rose 100-1,600 m above the summit and drifted E and W on most days; no emissions were observed on 7 June. 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.

Wed, 12 Jun 2024, 14:00JMA reported ongoing eruptive activity at Minamidake Crater (Aira Caldera's Sakurajima volcano) during 27 May-3 June with nighttime crater incandescence. Sulfur dioxide emissions were high, averaging 2,000 tons per day on 30 May. The Alert Level remained at 3 (on a 5-level scale), and the public was warned to stay 1 km away from both craters.
