Another small eruption occurred at the volcano yesterday evening at 19:28 local time, producing a plume of steam with some ash that rose approx. 600 m above the active crater.
A similar eruption had taken place on 7 Aug when the alert level was raised to 3 (on a scale of 1-5). It had later been lowered to 2 on 19 Aug. Yesterday's activity did not prompt JMA to raise the alert level again, but this is likely to occur should the activity of the volcano increase again in the near future.
