Veniaminof volcano (Alaska): weak ash emissions

A weak eruptive activity has started from the volcano. Since last night, weak ash emissions have appeared from the central cone of the caldera of the volcano.
The new activity is accompanied by a persistent steam plume and increasing volcanic tremor. So far there seem to be no lava flows or other significant eruptive processes.
The new ash emissions are very diluted and reach about 200-300 m height. They were first observed on the Aciation camera of Perryville from last night at around 17-18h local time. AVO who has not yet reported about the ash confirmed to Blog Culture Volcan that the plume indeed contains very small amounts of ash, which pose no problems to aviation (for now).
