This ash fall streak was a result of an explosive eruption of the volcano over a month earlier, on 10 April — the volcanic ash plume could be seen moving southward in Himawari-8 Visible (0.64 µm) images (below).

Thanks go out to Santiago Gassó for bringing this interesting feature to our attention.
In #Kamchatka today, this feature caught my attention. A long dark streak , it is not atmospheric, it appears lack of snow on the ground, it is there the previous days. I am not super familiar with the topo but I do not recall seeing it before. Any guess? some ground heating? pic.twitter.com/ShVbWCPJhF
