Sakurajima volcano (Kyushu Island, Japan): new explosive eruption

Eruption at Sakurajima in the evening of 25 Mar 2017 (image: @Rglove1211 / twitter)After several months of quiet, a vulcanian-type explosion occurred this afternoon (25 Mar) shortly after 18h local time(18:03).
The explosion seems to have come from the Minamidake summit crater and was relatively powerful; it appears to have produced small pyroclastic flows but only a relatively low ash plume (JMA indicates 500 m, but this is probably underestimated).
The volcano continued to vent ash (strombolian activity ?) for several hours following the initial eruption, then quieted down, but had a second eruption at 22:28 local time, with an eruption cloud rising 1400 m.
Whether the volcano is entering now a phase of more frequent explosions (as it had been doing typically during most of the past years until 2015) remains to be seen.
