Raikoke volcano (Kurile Islands): SO2 gas plumes continue to spread around the northern hemisphere

The activity at the small island volcano itself seems to have decreased a lot or even ceased - there are no more new ash alerts issued that mention new emissions at the volcano itself, and no significant heat signals can be found.

However, VAAC Anchorage continues to alert about the possible remaining ash clouds from the main phase of the eruption during 21-22 June. On the other hand, most of this ash must by now have been dispersed sufficiently to fall below direct detection by satellite-based sensors.
What is still clearly being detected is the significant SO2 gas plume: in various branches, it hovers over parts of Siberia, the northern Pacific and Alaska mainly at altitudes between 9-13 km.
