Wed, 27 Mar 2024, 15:00Japan Meteorological Agency (JMA) reported that the eruption at Suwanosejima's Ontake Crater continued during 20-26 March. Crater incandescence was observed nightly in infrared camera images. A total of seven explosions were registered by the seismic network; resulting ash plumes rose up to 1.3 km above the crater rim before drifting N and SE and ejected large ballistic projectiles (20-30 cm in diameter) as far as 600 m away from the center of the crater.

Wed, 27 Mar 2024, 15:00PVMBG reported that eruptive activity continued at Semeru during 20-26 March. During the week, 14 eruptive events were recorded by the seismic network, and ash plumes rose 500-1,200 m above the summit and drifted in multiple directions. During 20 and 23-24 March white and gray emissions rose 50-200 m above the summit and drifted multiple directions.

INSIVUMEH reported that eruptive activity continued at Santa Maria's Santiaguito lava dome complex during 20-26 March with a lava extrusion and 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 WSW flank lava flow. Daily explosions generated ash, gas, and steam plumes that rose as high as 900 m above the summit and drifted multiple directions on most days, and on 20 March rose 2.2 km above the summit.

Wed, 27 Mar 2024, 15:00Instituto Geofísico del Perú (IGP) reported that moderate levels of eruptive activity continued at Sabancaya during 20-26 March. The monitoring network recorded a range of 5-30 explosions per day. Explosions generated ash plumes that rose as high as 1.1 km above the summit crater and drifted less than 10 km in multiple directions; plume heights were not visible during 24-26 March.

Centro Nacional de Prevención de Desastres (CENAPRED) reported that eruptive activity continued at Popocatépetl during 20-26 March. Daily activity consisted of 14-69 long-period (LP) events that were accompanied by emissions of gas, steam, and small quantities of ash. Additionally, high-frequency and variable amplitude episodes of tremor were registered; duration of episodes ranged from approximately 2.9 to 17.6 hours per day.

Wed, 27 Mar 2024, 15:00Observatoire Volcanologique de Goma (OVG) reported that the sulfur dioxide (SO2) flux at Nyiragongo decreased slightly but remained at moderate levels during 18-23 March. The Munigi station measured a small increase in carbon dioxide (CO2) concentrations from fractures in the S area. Additionally, CO2 concentrations in the “mazuku”, or lowland areas located in the W area of the city of Goma, remained lethal.
