Stromboli (Eolian Islands, Italy): (23 May) The lava flow on the upper half of the Sciara del Fuoco remains active with very little visible changes in activity since yesterday overall. Apparently, lava effusion rates are stable for the moment and high enough to maintain the lava flow reaching about 400-500 m elevation, i.e. half way down to the sea.
Frequent small rockfalls from the margins and front of the flow occur, whirling up dust trails. Spattering and intermittent strombolian-type explosions can be seen from several of the summit vents.
The overall volcanic activity index for the volcano remains “high”.

Etna (Sicily, Italy): (23 May) The latest paroxysm of Etna occurred during last night 22-23 May 2021, following about 40 hours since the previous one during 20-21 May, and marking the 3rd such episode in a row in May or number 20 during the year 2021 so far.
Similar as during the preceding two eruptions, the main active vent was in the summit region of the New SE crater, the one known as “saddle vent” (because it used to be in a small depression between the old SE crater and the “New” SE crater, which has been growing a large cone complex to the side of it since 2011).

…22 May:
The 3rd paroxysm or lava fountaining episode in a row is occurring at the volcano right now.
After a gradual climb, activity rapidly increased at the New SE crater during the past hours and is now producing a lava fountain. An ash plume is rising several kilometers and drifting towards the east.
The current eruption came at almost exactly the same interval, approx. 48 hours, as between the previous two. It looks as if the volcano once again has embarked on a rhythmic pattern of paroxysms, similar to what had occurred during Feb-April earlier this year.

Fagradalsfjall (Reykjanes Peninsula, Iceland): After the lava overtook the artificial dam that had been quickly built in a (failed) attempt to prevent the lava from entering the Natthagi valley, it entered the valley which is leading towards the southern ring road. As it descended the northern headwall of the valley, it created a beautiful lava fall, then formed a new flow along the bottom of the valley and actually following and covering the hiking path leading from the parking at the ring road northwards to the eruption area.
Its front is now very close to the road, probably less than 2 km away and if the eruption continues at its steady (in fact gradually increasing) lava output rate, which is likely, it is only a question of time when and where exactly it will cut it. Small topographic hills and new artificial dams might only be gaining some valuable time, though.

…22 May:
The effusive eruption of the volcano continues mostly from the eruptive fissure vent #5 that started to erupt on 13 April.
Lava flows started to overflow into the adjacent Nátthagi valley as broke eastern defense barriers today to protect Suðurstrandavegur main road.

…23 May:
Earthquakes have been occurring in the area, as users reported via our quake report service and authorities confirmed. People are advised to remain vigilant, avoid non-essential movements, and follow directions.
…23 May:
According to a post by NewTimesRwanda, the eruption appears to subside and some of the residents who had fled from Goma to Rwanda are returning home.
…23 May:
The situation is quickly worsening. According to local reports, the lava flows have reached the airport and are now thought to cross the city (again, as in 2002) to reach Kivu lake.
Mass panic has broken out in Goma and thousands are fleeing into other locations including Rwanda across the nearby border. The situation is chaotic.

…22 May:
The flank effusive eruption of the volcano continues at high levels and illuminates the sky over the capital city of Goma.
The new eruptive fissure vent on the eastern flank, as reported by observers in social media, is feeding fast-flowing lava flows – thanks to the volcano’s extraordinarily fluid lavas at extremely low viscosity – that continue to advance towards Busambali, Byungo, Mudja province including Goma capital city and are expected to threaten inhabited areas.

…22 May:
A new flank eruption started at the volcano this afternoon. It seems that a fissure opened on the eastern(?) flank, and drained the lava lake inside the volcano.
Large lava flows can be seen on published imagery, but it seems that so far, the city of Goma, partially destroyed in 2002 during the last flank eruption of the volcano, is not threatened (yet).
