Bogoslof volcano (Aleutian Islands): another powerful explosion, ash to flight level 350

Ash plume from Bogoslof volcano this morning (Himawari 8, NOAA/CIMSS)
It produced a relatively large ash plume that rose to 35,000 ft (12 km) altitude and drifted NE at 40 knots. The aviation color code was immediately raised to red; this plume was very dangerous for aircraft in the area who should now avoid the vicinity of the island.
Satellite data show the plume clearly (animation):
In addition, the Alaska Volcano Observatory could "see" the trace of the explosion on seismic recordings from instruments on nearby volcanoes, in particular Okmok and Makushin.
So far, no new explosions have been detected, but it is more than likely that the volcano is in for a series of more explosions although it is impossible to know how big they might be.
