Steam plume from Aso's Nakadake crater today
The volcano continues to be at unrest. The main vent in the Nakadake crater continues to produce mild, sporadic ash emissions and intense degassing, creating a plume that rises few hundred meters.
Sat, 3 Oct 2015, 08:21
Weak ash plume rising from Aso's Nakadake crater this morning
After the strong explosion on 14 Sep, the volcano has been rather calm, but continues to emit dilute ash plumes. The volcano remains at level 3 (out of 5) and access to the Nakadake crater closed.
