Sakurajima volcano (Kyushu, Japan) activity update

Powerful strombolian explosion from Sakurajima at 13:48 UTC on 27 Sep (22:48 local time)
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.

JMA reported that 18 explosions from Sakura-jima's Showa Crater ejected tephra as far as 1,300 m during 17-20 September. Incandescence from the crater was visible some nights. Based on information from JMA and pilot observations, the Tokyo VAAC reported that during 18-20 and 22-23 September explosions generated plumes that rose to altitudes of 1.8-4.6 km (6,000-15,000 ft) a.s.l., and drifted SW, W, and NW. ...
