Etna (Sicily, Italy): Last night's eruptive episode of tall lava fountains, known as paroxysm, turned out to be one of the most impressive and powerful in recent years. Not only did it produce higher fire fountains than usually, but also it lasted longer than most other paroxysms.
Around 10:30 p.m. local time, volcanic tremor and strombolian activity from the New SE crater began to increase drastically. Half an hour later, a first lava flow started to descend from the eastern summit vent of the crater, and activity continued to increase, soon forming fountains of a few hundred meters tall.

...20 Feb:
The 4th paroxysm within little more than 4 days is occurring at the time of this update! Starting in the evening of 20 Feb 2021, the explosive activity at the New SE crater gradually increased and developed into sustained lava fountains now approx. 300 m tall, and still rising.
A lava flow has started to descend towards the Valle del Bove and although obscured by the night, a tall ash and steam plume is rising above the summit region of the volcano. As spectacular as it looks, these eruptions pose no threat to inhabited areas, although the ash plumes can be dangerous to aircraft and the lapilli and ash falls are a (rather common) nuisance to the downwind areas around the volcano.

Klyuchevskoy (Kamchatka): A new eruption started at the volcano very recently, this time not from the summit vent, but a fissure at the northwestern flank at relatively low altitude of 2500-2700 m above sea level.
Since the end of the impressive lava flow from the summit crater, which had been active for several months, but ceased in early February this year, the volcano rested only about 2 weeks before starting its current new eruption.
Russian volcanologists reported that new cinder cones have been forming around the new flank vents. Lava flows at the surface can be seen on satellite imagery.
