| Current State: |
A growth of the lava dome continues, a strong fumarolic activity sometimes with some amount of ash, and an incandescence of the eastern part of the lava dome and hot avalanches accompanie this process. Satellite data showed a thermal anomaly over the lava dome all week.  |
| Danger Prognosis for Aviation: |
The extrusive eruption of the volcano continues. Ash explosions up to 32,800-49,200 ft (10-15 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft. |
