Ash plume rose 9.4 kilometres in the air.

At 18:45 UTC the ash cloud reached 9.7 km (32 000 feet) above sea level forcing the AVO to raise the Aviation Color Code to RED and the Alert level to WARNING.

Seismic data suggest that the ash emissions may still be going on. An interesting video by DahBoo7:

Strong eruption of Shevelush volcano on August 8, 2017

A day after, Shevelush showed to the world what he was able to do. The huge eruption – 16:31 UTC on August 8, 2017 – sent a plume of ash and gas 12.2 km (40 000 feet) above sea level.

About 5 hours after the explosion, the plume was measuring 220 km (137 miles) nd had already drifted 360 km (224 miles) SSE of the volcano.
