JMA reported that the number of explosions per day at Suwanosejima's Ontake Crater had increased on 16 September and remained elevated through 27 September. A total of 105 explosions were recorded during 20-27 September. Eruption plumes mainly rose as high as 2.9 km above the crater rim and material was ejected as far as 800 m away from the crater.
Ashfall was reported in Toshima village (4 km SSW). Notably, an explosion at 2349 on 20 September ejected material as far as 1.2 km SE. At 0711 on 26 September an eruptive event produced a plume that rose 5.4 km; weather clouds prevented confirmation of ejected bombs, but a large amount of ash fell in Toshima village.
The Alert Level remained at 3 and the public was warned to stay 2 km away from the crater.
