The event was most likely a partial collapse of the existing dome with possible explosions, since the ash emitted was mostly red (indicating it originated from old, altered lava).

KVERT reported ashfall SW of the volcano reaching villages Klyuchi (2mm of ash measured) and Lazo (1mm of ash). Ash plumes were extending to the south-east and south-west of the volcano.
