Etna (Sicily, Italy): (20 Jan) Last night's activity of vigorous and near-constant strombolian explosions from the eastern summit vent of the New SE crater continued to increase, but judging from webcam imagery, it did not quite reach the intensity of previous paroxysms with true lava fountains.
During the most intense phase, starting around 1:45 am local time, a new lava flow was emitted from either the same vent at the summit of the New SE crater or a fissure beneath it, and descended approx. 200-300 m to the flat area at its northeastern base.

...20 Jan:
During the past hours, activity from the New SE crater has been increasing significantly and is currently showing intense and near-constant strombolian explosions. It seems very much as if it is heading for another paroxysm in the next hours if not less.
The volcanic tremor signal is also on an increasing trend.
During most of the day, when visibility allowed views, there were small and irregular ash emissions, likely related to smaller explosions from the New SE crater. In the evening, constant glow and intermittent explosions were visible. These have been increasing significantly during the past few hours.

Klyuchevskoy (Kamchatka): (20 Jan) Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ERUPTION AT 20210120/0240Z FL200 EXTD SW REPORTED OBS VA DTG:20/0310Z

Suwanose-jima (Ryukyu Islands): The explosive eruption of the volcano continues. Near-constant vulcanian activity is characterized by occasional strong explosions as it occurred today.
The eruption started at Suwanosejima volcano at about 15:50 local time. A dense dark ash plume rose to estimated 6,000 ft (1,828 m) altitude and drifted W. Ejected blocks reached distance approx. 400 m away from the crater.

...20 Jan:
The eruption continues on its gradually increasing trend. Pyroclastic flows - turbulent and hot avalanches of hot lava rocks, ash and volcanic gasses mixed together - are being released from the growing dome and now descend the SW flank of the volcano.
This morning, a glowing avalanche reached 1200 m in the Kali Krasak drainage at 05:35 local time.
