Disaster prevention
- Large volcanic rocks that follow a ballistic trajectory may be scattered up to approximately 3 km from Mount Shinmoe's crater, and pyroclastic flows may reach up to about 2 km. Therefore, please remain alert within a 3 km radius of Mount Shinmoe's crater.
- On the downwind side, not only volcanic ash but also small volcanic rocks may be carried over long distances by the wind and fall, so please exercise caution.
- Just like in 2011 atmospheric vibrations associated with the eruption could cause windowpanes to shatter. Please exercise caution.
