Actually, there’s now activity at 27 different volcanoes, says volcanodiscovery.com.
Kizimen (Kamchatka): “An ash plume rising to 17,000 ft (5 km) altitude was reported on Dec 27 by VAAC. Webcam images show a significant steam plume which possibly contains ash. This suggests that the lava dome might be entering a new phase of growth.”
Karymsky (Kamchatka): “Strombolian to mild vulcanian explosions continue at the volcano. VAAC Tokyo reported an ash plume at 15,000 ft (4,5 km) altitude on Dec 27.”
