Klyuchevskoy (Kamchatka): (11 Oct) We posted the following time-lapse video of the eruption this morning (or evening, in Kamchatka time). At 08:30 UTC (17:30 local time), a new vent opened in the saddle between Klyuchevskoy and neighboring Kamen volcano, producing a fountain of lava and ash rising to about 7 km altitude. The KVERT webcam even captured lightning during this eruption:

Soufriere Hills (Montserrat, West Indies (UK)): (11 Oct) MVO reported that activity at the Soufrière Hills Volcano has remained low over the past week. The dome produced a number of rockfalls and a few volcano-tectonic earthquakes. Volcanic gas emissions were at average levels.
Jebel Zubair (Red Sea): (11 Oct) As of today, the submarine eruption continues with the production of a steam plume of variable size, not always easily identifiable on satellite images. A SO2 plume is also visible on satellite data drifting from the eruption site.
No ash can be seen on satellite imagery, only steam, and the area of discolored water (indicator of suspended particles) is small if not has disappeared. That suggests that the eruption is currently rather weak and probably has not yet entered the so-called surtseyan phase where solid fragments (ash, lava blocks) are ejected above the surface of the sea.
