Wed, 17 Apr 2024, 14:00PVMBG reported that Ibu continued to erupt during 10-16 April. White-and-gray ash plumes rose 200-2,000 m above the summit and drifted in multiple directions almost daily; white plumes rose 200-500 m above the summit and drifted SE, W, and NW on 15 April. The Alert Level remained at 2 (the second highest level on a four-level scale), with the public advised to stay outside of the 2 km hazard zone and 3.5 km away from the N area of the active crater.

AVO reported that slow lava effusion in Great Sitkin's summit crater was last confirmed in a 10 April radar satellite image with continuing inflation over the vent and advancement of the NW and E lava lobes. Effusion likely continued during 11-16 April. Seismicity was low with a few small daily earthquakes recorded by the seismic network.

JMA reported ongoing eruptive activity at Minamidake Crater (Aira Caldera's Sakurajima volcano) during 8-15 April with nighttime crater incandescence. An explosion at 2137 on 10 April produced an ash plume that rose 500 m above the crater rim and ejected large blocks 1.2 km from the vent. Sulfur dioxide emissions were extremely high, averaging 4,300 tons per day on 12 April.
