Sakurajima volcano (Kyushu, Japan) activity update

Powerful strombolian explosion from Sakurajima at 13:48 UTC on 27 Sep (22:48 local time)
Activity fluctuates on a scale of few days, but remains at relatively high levels overall. Explosions from the Showa crater often follow each other at intervals of few hours, and ash plumes regularly surpass 10,000 ft altitude (something that had been more rare during the past years).
Strong vulcanian explosion from Sakurajima in the afternoon of 27 Sep (08:24 UTC, 17:24 local time); ash plume reached 13,000 ft.
Most explosions are of vulcanian type (strong fragmentation of solid material blocking the vent, generation of tall ash plumes, often with shock waves and explosion sounds) and more rarely strombolian, with mainly incandescent lava ejected in fountains of several hundred meters and only little ash.
Following most explosions, the volcano usually continues to near-constantly emit ash plumes of various size for several hours. These plumes, when observed during the past days, were up to about 500 m tall, with sometimes weak strombolian activity visible reaching above the crater rim.

Activity remains at high levels with near-constant ash venting and frequent and often large vulcanian explosions (ash plumes rising to 10,000 ft / 3 km altitude and more). Today's activity seen from the south: ... [more]

Activity remains elevated. The volcano produces near-constant ash venting and relatively many (3+ per day) vulcanian-type explosions. Ash plumes have been rising up to 14,000 ft (4.2 km) during the past 2 days. ... [more]

An explosion this morning produced an ash plume rising to 14,000 ft (4.2 km) altitude. This is the latest of the currently intense eruptive phase of ash emissions and frequent vulcanian explosions (at least 6 during yesterday). [more]

JMA reported that 15 explosions from Sakura-jima's Showa Crater ejected tephra as far as 1,300 m during 2-6 September. Incandescence from the crater was visible some nights. An explosion at 1100 on 4 September generated an ash plume that rose 2.8 km and drifted S, causing ashfall in areas downwind including Arimuracho (4 km SSE). Tephra 4 cm in diameter was confirmed in an area 3 km S, and tephra 1 cm in diameter was reported 10 km SSE. ... [more]
