Global Volcanic Activity - Ongoing Activity for the week of 5 June - 11 June 2019

Agung | Bali (Indonesia) : PVMBG reported that at 1212 on 10 June an explosion at Agung produced a gray ash plume that rose about 1 km and drifted SE and E. The Alert Level remained at 3 (on a scale of 1-4) with the exclusion zone set at a 4-km radius.

Aira | Kyushu (Japan) : JMA reported that during 3-10 June very small eruptive events at Minamidake crater (at Aira Caldera’s Sakurajima volcano) were recorded, as well as periodic crater incandescence. The Alert Level remained at 3 (on a 5-level scale).

Dukono | Halmahera (Indonesia) : Based on satellite and wind model data, and notices from PVMBG, the Darwin VAAC reported that during 5-11 June ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted in multiple directions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions on 3 June that sent ash plumes up to 3 km (10,000 ft) a.s.l. The plumes drifted E. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Kerinci | Indonesia : PVMBG reported that at 0604 on 7 June a grayish ash emission from Kerinci rose 800 m above the summit and drifted E according to a ground observer. The Alert Level remained at 2 (on a scale of 1-4), and tourists were warned to remain outside of the 3-km exclusion zone.

Klyuchevskoy | Central Kamchatka (Russia) : On 12 June ash plumes from Klyuchevskoy rose to an altitude of 5 km (16,400 ft) a.s.l. and drifted 10 km N, prompting KVERT to raise the Aviation colour Code to Orange (the second highest level on a four-colour scale). Ash emissions continued later that day with plumes rising to 5 km a.s.l. and drifting 68 km WNW.

Krakatau | Indonesia : PVMBG reported that Anak Krakatau’s seismic network recorded one eruptive event at 0850 on 10 June. The event as not followed by visible ash emissions, though observations were hindered by weather conditions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km radius hazard zone from the crater.

Manam | Papua New Guinea : The Darwin VAAC reported that during 7-8 June ash plumes from Manam rose to an altitude of 4.3 km (14,000 ft) a.s.l. and drifted SW, based on satellite data and weather models.

Merapi | Central Java (Indonesia) : PVMBG reported that during 3-10 June the lava-dome volume at Merapi did not change and was an estimated 458,000 cubic meters, based on analyses of drone footage. Extruded lava fell into the upper parts of the SE-flank, generating one block-and-ash flow that traveled 1 km down the Gendol drainage on 9 June. White plumes rose as high as 75 m above the summit. The Alert Level remained at 2 (on a scale of 1-4), and residents were warned to remain outside of the 3-km exclusion zone.

Rincon de la Vieja | Costa Rica : OVSICORI-UNA reported that a 10-minute-long eruption at Rincón de la Vieja began at 0343 on 11 June. Emissions were not visible due to weather conditions.

Sabancaya | Peru : Instituto Geofísico del Perú (IGP) reported that during 3-9 June an average of 12 explosion per day were recorded at Sabancaya. Ash plumes rose 2.9 km above the crater rim. On 7 June explosions generated ash plumes that drifted 30 km S and SW. The public was warned to not approach the crater within a 12-km radius.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch’s lava dome was identified daily in satellite images during 1-7 June. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Stromboli | Aeolian Islands (Italy) : INGV reported that during 3 and 6-9 June activity at Stromboli was characterized by ongoing Strombolian explosions and degassing from multiple vents within the crater terrace. Explosions from two vents (N1 and N2) in Area N (north crater area, NCA) occurred at a rate of 1-4 per hour, ejecting material 80 m high and producing ash plumes. Explosions from two vents (S1 and S2) in Area C-S (South Central crater area) occurred at a rate of 3-8 per hour, ejecting material 80-150 m high. Gas plumes rose from vent C.
