News and Updates on Volcanoes and Earthquakes

The Darwin Volcanic Ash Advisory Centre (VAAC) reported that an ash plume from Manam was identified in a satellite image at 1020 on 16 May drifting SE. The plume had dissipated by 1220. ... Διαβάστε όλα

The Japan Meteorological Agency (JMA) reported ongoing eruptive activity at Minamidake Crater (Aira Caldera's Sakurajima volcano). No eruptive events were recorded during 5-15 May, though inflation continued to be detected in deformation data, notably starting at 2000 on 12 May. Sulfur dioxide emissions were slightly low, averaging 300 tons per day (t/d); the last measurement was 900 t/d on 2 May. ... Διαβάστε όλα

On 13 May GeoNet reported near-continuous emissions of gas, steam, and minor amounts of ash at Whakaari/White Island based on visual observations during overflights, visual observations from the Bay of Plenty coast, and from webcams located at Whakatane and Te Kaha. Additionally, minor amounts of ash were identified in satellite data as reported by the Wellington Volcanic Ash Advisory Center (VAAC). As seen from the coast, the plume occasionally rose 300-600 m above the summit during calm weather conditions, but during windier conditions the plume was lower and was visible downwind for tens of kilometers. ...

The Japan Meteorological Agency (JMA) reported that eruptive activity at Suwanosejima's Ontake Crater continued during 5-12 May. Incandescence was observed nightly in webcam images. No explosions were detected, though plumes from eruptive events rose 900 m above the crater rim. ... Διαβάστε όλα

The Sezione di Catania - Osservatorio Etneo (INGV) reported that eruptive activity continued at Stromboli during 5-11 May. Webcam images showed Strombolian activity at four vents in Area N within the upper part of the Sciara del Fuoco and from at least two vents in Area C-S (South-Central Crater) on the crater terrace. The vents in Area N continued to produce low- to medium-intensity explosions at a rate of 6-9 events per hour, ejecting lapilli and bombs less than 150 m above the vents. ... Διαβάστε όλα

The Kamchatkan Volcanic Eruption Response Team (KVERT) reported that lava extrusion may have continued at Sheveluch's “300 years of RAS” dome on the SW flank of Old Sheveluch and at the Young Sheveluch dome during 1-8 May. Thermal anomalies over the domes were identified in satellite images almost daily. The Aviation Color Code remained at Orange (the second highest level on a four-color scale). ... Διαβάστε όλα

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that activity continued at Semeru during 7-13 May, with multiple daily eruptive events recorded by the seismic network. Daily white-and-gray ash plumes rose 400-1,000 m above the summit and drifted in multiple directions. Weather clouds mostly obscured views on 7 May. ... Διαβάστε όλα

The Instituto Nacional de Sismología, Vulcanología, Meteorología e Hidrología (INSIVUMEH) reported ongoing eruptive activity at Santa Maria's Santiaguito dome complex during 6-13 May with continuing lava extrusion at Caliente dome. Daily explosions, as many as five per hour when reported, sometimes generated gas-and-ash plumes that rose as high as 1 km above the dome and possibly drifted as far as 15 km E, S, SW, and W. Effusion of blocky lava and collapses of material produced block avalanches that descended multiple flanks; the collapsed material sometimes produced short pyroclastic flows. ... Διαβάστε όλα

The Instituto Geofísico del Perú (IGP) reported low levels of unrest at Sabancaya during 5-11 May, with no explosions, thermal anomalies, or significant deformation. Gas-and-steam plumes rose as high as 1 km above the summit and drifted less than 10 km SW and SE. Sulfur dioxide emissions were at low levels, averaging 211 tons per day. ... Διαβάστε όλα
