Wed, 15 May 2024, 14:00PVMBG reported that eruptive activity continued at Semeru during 8-14 May. White-and-gray ash plumes rose 300-800 m above the summit and drifted in multiple directions during 8-9 and 12-14 May. Several additional eruptive events were recorded during the week by the seismic network, though plumes were not visually confirmed.

IMO reported that no active lava in the cone just E of Sundhnúk and along the fissure within the Reykanes volcanic system was visible in aerial photos taken during the evening of 8 May, indicating that the eruption was over. The Aviation Color Code remained at Orange (the second highest level on a four-color scale) because magma continued to accumulate at depth at a consistent rate, increasing the likelihood of a new eruption. Seismicity was relatively stable with 50-80 earthquakes recorded each day during the previous week.

Wed, 15 May 2024, 14:00PVMBG reported that an eruption at Lewotobi's Laki-laki volcano continued during 8-14 May. White steam-and-gas plumes rose 50-150 m above the summit and drifted in multiple directions during 8-9 and 12 May; eruptive events were occasionally recorded during those days though emission details were unknown. Gray-to-white ash plumes rose 50-200 m above the summit and drifted SW and W during 10-11 and 13-14 May.

Wed, 15 May 2024, 14:00Instituto Geofísico-Escuela Politécnica Nacional (IG-EPN) reported that the eruption at Fernandina decreased during 8-14 May. Sulfur dioxide emissions, measured using satellite data, ceased to be detected on 8 May, possibly indicating a decline in activity. Daily thermal anomalies from the lava flow were identified in satellite images.

KVERT reported that moderate explosive activity was ongoing at Ebeko during 3-10 May According to volcanologists in Severo-Kurilsk (Paramushir Island, about 7 km E), explosions on 2 and 6 May generated ash plumes that rose as high as 2.5 km (8,200 ft) a.s.l. and drifted SE and S. A thermal anomaly was identified in satellite images on 3 and 6 May; on other days either no activity was observed or weather conditions prevented views.

Wed, 15 May 2024, 14:00PVMBG reported that the eruption at Dukono was ongoing during 8-14 May. Gray-and-white ash plumes rose 450-1,200 m above the summit and drifted E and SE almost daily; emissions were not observed on 14 May. 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, 15 May 2024, 14:00Instituto Geofísico del Perú (IGP) reported that thermal anomalies from the main crater floor at Ubinas were identified almost daily during 7-14 May. Ash, gas, and steam plumes rose to 1.1 km above the crater rim during 7-8 May. Similar plumes emitted continuously for a period of time on 12 May rose to 1.1 km above the crater rim and drifted S and SE.

Tonga Geological Services reported that unrest at Tofua continued during 8-14 May. Thermal anomalies were detected daily and had intensities that fluctuated at low levels. The Aviation Color Code remained at Yellow (the second lowest color on a four-color scale); the Maritime Alert Level remained at Orange (the second highest level on a four-color scale) and mariners were advised to stay 2 km away from the island; the Alert level for residents of Vava'u and Ha'apai remained at Green (the lowest color on a four-color scale).
