Karymsky volcano (Kamchatka): elevated activity, frequent explosions
The current activity is likely consisting of strombolian to vulcanian-type explosions at irregular, but possibly very frequent intervals. The volcano is extremely remote from any populated center and road, and only accessible by helicopter or via day-long treks. There is no ground monitoring of the volcano.
If activity continues, we might try visit it during our upcoming Volcano Special tour to Kamchatka 16-24 March.
KVERT reported on 16 February that a satellite image captured an ash plume from Karymsky drifting 55 km SE at altitudes of 2.5-3 km (8,200-10,000 ft) a.s.l.
The Aviation Color Code was raised to Orange (the second highest level on a four-color scale). According to the Tokyo VAAC a possible ash plume on 17 February rose to 3.7 km (12,000 ft) a.s.l. and drifted SE. A weak ash plume drifting 117 km ESE was visible in satellite images on 18 February.
