JMA reported that eruptive activity at Suwanosejima's Ontake Crater continued during 29 April-6 May. Crater incandescence was observed nightly in webcam images. Emissions rose as high as 600 m above the crater rim and blocks were ejected as far as 300 m from the crater's center; no explosions were detected.
Wed, 8 May 2024, 14:00PVMBG reported that eruptive activity continued at Semeru during 1-7 May and seismicity remained at high levels. One incandescent lava avalanche traveled 800 m down the Besuk Kobokan drainage on the S flank. Eruptive events were recorded by the seismic network during 1-2 May, though plumes were not visually confirmed.

INSIVUMEH reported that eruptive activity continued at Santa Maria's Santiaguito lava-dome complex during 30 April-7 May with a lava extrusion and blocks avalanches at the Caliente dome. Incandescence from the dome was visible during most nights and early mornings, and occasional incandescence was also present along the upper parts of the lava flow on the WSW flank. Daily explosions (1-5 per hour on most days) generated gas-and-ash plumes that rose 600-1,400 m above the summit and drifted as far as 25 km W, SW, S.

Wed, 8 May 2024, 14:00Instituto Geofísico del Perú (IGP) reported that the eruption at Sabancaya continued at moderate levels during 29 April-5 May with a daily average of 36 explosions. Gas-and-ash plumes rose as high as 2.5 km above the summit and drifted less than 10 km E, SE, and S. Thermal anomalies over the lava dome in the summit crater were identified in satellite data.

On 7 May IMO reported that the cone just E of Sundhnúk and along the fissure within the Reykanes volcanic system continued to erupt lava, though activity had decreased during the previous few days. Lava flowed short distances from the vent; no significant changes were observed at the S part of the flow field near the earthen barriers at Grindavík. Inflation from magma accumulation beneath Svartsengi was first detected at the beginning of April and the rate of inflation was unchanged for the past few weeks based on modeling of GPS and satellite data.

Wed, 8 May 2024, 14:00Servicio Geológico Colombiano's (SGC) Observatorio Vulcanológico y Sismológico de Manizales reported that eruptive activity at Nevado del Ruiz continued during 30 April-6 May. The number of seismic events associated with fluid movement remained stable at low-to-moderate levels, though the signal increased in magnitude. Some of these signals were associated with pulsating emissions of ash and gas; ash plumes rose as high as 2 km above the summit on 30 April and drifted NW and WNW.

BPPTKG reported that the eruption at Merapi (on Java) continued during 26 April-2 May. Seismicity had declined compared to the previous week. The SW lava dome produced 113 lava avalanches that traveled as far as 2 km down the SW flank.

Wed, 8 May 2024, 14:00PVMBG reported that eruptive activity at Marapi (on Sumatra) was ongoing during 1-7 May. White steam-and-gas plumes rose 200-300 m above the summit and drifted multiple directions almost every day. White-and-gray ash plumes rose 250-300 m above the summit and drifted E and SE on 6 May.

PVMBG reported that the eruption at Lewotolok continued during 1-7 May. White steam-and-gas plumes rose 100-700 m above the summit and drifted W and NW on most days. Gray-to-black ash plumes rose 300-500 m and drifted W on 6 May.

Wed, 8 May 2024, 14:00PVMBG reported that gray-to-white ash plumes rose 100-500 m above the summit of Lewotobi's Laki-laki volcano and drifted in multiple directions during 30 April-5 May. The plumes were sometimes dense. Eruptive events were recorded by the seismic network on 6 May, though no emissions were reported.

PVMBG reported that Ibu continued to erupt. A few notable eruptive events occurred during 24-29 April. On 24 April ash plumes rose 800-1,500 m above the summit and roaring was heard at the Ibu observation post (9 km W).

Wed, 8 May 2024, 14:00AVO reported that slow lava effusion in Great Sitkin's summit crater was last confirmed in a 30 April radar satellite image; effusion likely continued during 30 April-7 May. Seismicity was low. Weather clouds fully or partly obscured satellite and webcam views, though minor steaming from the vent area was observed in satellite images during 30 April-2 May.
