Per the Guardian, the erupting volcano,
"Ibu is one of Indonesia’s most active volcanoes, erupting more than 21,000 times last year. "
Doesn't that translate to it erupted all year long? How are we defining an eruption if we can count multiple eruptions a day?
Hörður Kristleifsson posted another of his 360 degree aerial panoramas of the eruption site in Iceland. This one was taken right after the eruption officially ended and you can seen down into the splatter cone, now devoid of lava.
Very cool and neat tool for getting an idea of the ground coverage this cycle of eruption produced.
The Icelandic Met has issued a new bulletin about magma buildup in the Svartsengi area. Their current estimate of magma buildup based on surface deformation/land rise is 14 million cubic meters, which is equal or greater to the amounts which previously triggered eruptions in the area. They're advising that another eruption may be imminent and with very little warning, as the ground is already heavily fractured.
When Hunga Tonga-Hunga Ha’apai erupted in January 2022, the underwater volcano in the South Pacific unleashed the most intense lightning storm ever recorded and set off a mega-tsunami that was hundreds of feet high. Research indicated the eruption was fueled by two merging magma chambers. Now, scientists are looking at another potential trigger.

In Iceland, they're in the process of building a second set of magma defense berms on Grindavik's eastern flanks. The primary berm system has been overflowed twice in recent weeks and lava piled up behind the existing berms is taller than the berms now across much of their length.
The new berms will be 6 meters high and offset from the original ones by about 120 meters.
The problem as I see it is there isn't really a way for this new berm system to rechannel/divert lava which spills over elsewhere. It's more forming a "catchment basin" with with a fixed dimension and volume. When it's full, it's full.
Right now, it's what they can do. Mother nature doesn't argue, she simply does what she does. Will she keep spewing out lava in this location for years?
Looks like we're starting to see a lot of small but very shallow tremors in the vicinity of Svartsengi. Svartsengi has continued to see significant land uplift even with the outflow of magma in the area, indicating significant and rising magma levels below the surface. How much longer until the area sees another significant eruption?
Un tableau qui résume l'augmentation du volume de lave de ces derniers mois, ayant engendré la création d'une digue (symbole carré) ou d'une éruption (symbole étoile). Et là, on doit frôler les 10 millions de mètre cube donc oui, c'est imminent !

VAN HALEN's "Eruption" Played On 7-String Violin Is Impressive
"I haven’t worked this hard since my masters recital on classical violin. I’ve ripped up my fingers to shreds, they bled, they blistered."
