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

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.
