Etna (Sicily, Italy): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse warned about a volcanic ash plume that rose up to estimated 19000 ft (5800 m) altitude or flight level 190 and is moving at 15 kts in SE direction.
The full report is as follows: ERUPTION AT 20210331/1911Z WITH WEAK ASH EMISSION OBS VA DTG:01/1300Z to 19000 ft (5800 m)
...1 Apr:
The 17th paroxysm (lava fountain episode) from the New SE crater in a row has been going on all night, and is still increasing as of 9 am this morning local time, making it a record-breaker in terms of duration.
The National Institute of Geophysics and Volcanology (INGV) in Catania reported that strombolian activity at the SE Crater passed to sustained lava fountains from around midnight, meaning that these now have been continuing for more than 9 hours! The eruption column has been rising to an altitude of approx. 7 km (20,000 ft) and dispersing towards the SSW, where it is raining black lapilli and volcanic sand now.

...31 Mar:
During the past hours, activity has gradually been (and still is) increasing at the New SE crater, and it has entered the lava fountaining or paroxysmal phase.
While activity from the the new eruptive vent that opened this morning at the southern base of the SE crater continued to increase, feeding lava flows, in particular one directed south and southwest towards the Valle del Bove, the summit vent has been activated again to join the action. Its activity began with smaller explosions that quickly grew in intensity and now started to generate lava fountains, constantly increasing in height and likely already surpassing 200 meters as of now.

Asama (Honshu): The Japan Meteorological Agency (JMA) raised the alert level for the volcano to level 2, as an elevated seismic activity and slight inflation has been recorded.
Since 15 March the seismic station recorded a slight ground deformation on the western flank of the volcano indicating magma moving upwards through the volcanic conduits.

Tanaga (Aleutian Islands): (1 Apr) Low power likely due to snow cover has resulted in loss of operation and communication with all but two seismic stations at the volcano.
As a result, the Alaska Volcano Observatory (AVO) can no longer locate earthquakes that could indicate unrest at Tanaga, and the Aviation Color Code and the Volcano Alert Level are now designated as Unassigned.
