Ash plume and pyroclastic flow from the eruption of Kuchinoerabujima this morning
A powerful vulcanian explosion occurred this morning at 11:02 am local time at the volcano. The eruption - a both vertical and partially lateral massive explosion, occurred with apparently little warning from the Shintake vent and produced large pyroclastic flows by column collapse. A tall mushroom ash plume quickly rose to approx. 12 km altitude (36,000 ft).

Steam (and ash?) plume from Nevado del Ruiz yesterday
Unrest continues at the volcano. Strong steam emissions, sometimes mixed with light ash continue, accompanied by elevated seismic activity inside the volcano.

:
(26 May) As of yesterday evening, the eruption has decreased a lot in intensity. Lava fountaining at the 1 km fissure vent had essentially stopped. The lava flows, still far from the sea, were only weakly alimentated and advancing slowly.

PVMBG reported that during 20-27 May white plumes were observed rising as high as 100 m above Soputan even though inclement weather sometimes obscured crater views. Variable seismicity was dominated by volcanic earthquakes and signals indicating emissions and avalanches. Low-frequency harmonic tremor was occasionally detected.

Wed, 27 May 2015, 06:00AVO reported that seismicity at Shishaldin continued to be elevated over background levels 27 May-2 June, indicating that low-level eruptive activity confined to the summit crater likely continued. Elevated surface temperatures were periodically detected in satellite images, and minor steaming was recorded by the webcam during 27-28 May. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Wed, 27 May 2015, 06:00During 27 May-2 June IG reported moderate seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador; cloud cover sometimes prevented visual observations. On 27 May a steam-and-ash plume rose 1 km and drifted SW. The next day frequent vapor emissions with a slight amounts of ash rose 800 m above the crater and mainly drifted NW.

CENAPRED reported that during 27 May-2 June the seismic network at Popocatépetl recorded 60-145 daily emissions consisting of water vapor, gas, and ash; cloud cover sometimes prevented visual observations. Explosions occurred daily, and nighttime crater incandescence was observed. Gas-and-steam plumes drifted in multiple directions.

HVO reported that seismicity beneath Kilauea's summit, upper East Rift Zone, and Southwest Rift Zone was at background levels during 27 May-2 June. The lava lake continued to be active in the deep pit within Halema'uma'u Crater; the lake level was about 44 m below the crater floor on 29 May and 73 m below the floor on 31 May. The June 27th NE-trending lava flow continued to be active with surface flows within 7.9 km NE of Pu'u 'O'o.

JMA reported 18 explosions during 25-29 May and 24 during 29 May-1 June from Showa Crater at Aira Caldera's Sakurajima volcano, some that ejected tephra as far as 1,300 m, and incandescence from the crater was occasionally visible at night. On 29 May and 1 June explosions generated large ash plumes that rose 3.3 km above the crater. The Alert Level remained at 3 (on a 5-level scale).
