A field survey conducted on November 9th confirmed a tiny amount of ashfall around 2 km southwest of Otake crater. In addition, according to the Toshima Village administration, ashfall was observed in the settlement in the island (about 4 km south-southwest of Otake) on November 25th. A field survey at Bunka crater on November 8th revealed no remarkable change in the shape of the inside of the crater. Infrared images showed no significant change in temperature distribution at the crater.
Seismic activity remained at low levels. Volcanic tremors have occurred almost continuously since September 28th 2012, and especially in November, occurred at all times. The total tremor duration in November was 720 h (705 h 19 m in October).
