PVMBG 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. ... Read all

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. ... Read all

BPPTKG reported that the eruption at Merapi (on Java) continued during 3-9 May. Seismicity had intensified compared to the previous week. The SW lava dome produced 176 lava avalanches that traveled as far as 2 km down the Bebeng drainage on the SW flank. ... Read all

The Darwin VAAC reported that on 12 May an ash plume from Manam rose to 4.6 km (15,000 ft) a.s.l. and drifted E based on satellite images and weather models. The plume had dissipated by 0030 on 13 May. ... Read all

PVMBG 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. ... Read all

AVO reported that slow lava effusion in Great Sitkin's summit crater likely continued during 8-14 May. Seismicity was low. Weather clouds fully or partly obscured satellite and webcam views. ... Read all

Instituto 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. ... Read all

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. ... Read all

PVMBG 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. ... Read all

JMA reported ongoing eruptive activity at Minamidake Crater (Aira Caldera's Sakurajima volcano) during 6-13 May with nighttime crater incandescence. Very small eruptive events were recorded. Sulfur dioxide emissions were high, averaging 2,000 tons per day on 7 May. ... Read all
