Klyuchevskoy (Kamchatka): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 18000 ft (5500 m) altitude or flight level 180 and is moving at 25 kts in SE direction.
The full report is as follows: VA EMISSIONS CONTINUING OBS VA DTG:21/1120Z to 18000 ft (5500 m)
