As predicted/expected . . . Iceland's volcano is an ongoing eruption. It behaves like the Hawaiian eruptions, except it is on top of the lengthy Atlantic oceanic rift, while the Hawaiian volcano is essentially a hotspot complex.
"After centuries of quiescence, Iceland's Reykjanes Peninsula has erupted twice in less than a year, sending up fountains of incandescent rock. The latest eruption, which started at 1:18 p.m. local time on August 3, opened up at a fissure only a few hundred feet away from the cone crafted by last year’s volcanic outburst."
Interesting the report is about "Iceland's Reykjanes Peninsula". Maybe because of the many fissures that have individually opened up that have all been part of a larger complex than the named volcanic peak which seemed central to the fissuring when the erupting started a year ago in March 2021. Clearly the Reykjanes Peninsula is central to all the erupting.

Iceland eruption may be the start of decades of volcanic activity

"When was the last volcanic eruption in Iceland?
“This could be the beginning of second stage.” Iceland, located above a volcanic hot spot in the North Atlantic, averages one volcanic eruption every four to five years. The last one was at Holuhraun in 2014, when a fissure eruption spread lava the size of Manhattan over the interior highland region."

SGT (Join to see) The entire Atlantic Oceanic Rift is more or less a "hotspot"! Lol. However, Iceland is on top of a mantle plume in the rift, and uniquely located on top of and on each side of that rift, at a juncture of two of earth's major tectonic plates.
Remember when the peninsula volcanism started last year after a very long time of no erupting in that particular area? Went on a while before it stopped, or visibly stopped for all intents and purposes! A friend's grown son took a vacation to Iceland after a divorce, a while back before starting work at Los Alamos, and was disappointed the rather relatively accessible peninsula volcanism was inactive while he was there. He loved Iceland anyway. Thought it was wonderful! Imho, Iceland would be a very interesting place to visit . . . including the people. My chemistry class prof a number of years ago, was a woman from the Philippines who was married to a man from Iceland, so she talked to the class, a bit, about what it was like there.
The link provides a brief description of the Iceland's geologic uniqueness, which is better in its briefness than many sources.
also from icelandontheweb:
"Iceland is a place where a mid-ocean ridge can be seen on land.
What's more, Iceland is probably the only place in the world where the effects of two major tectonic plates drifting apart can easily be observed above sea level."

Remind us PO1 William "Chip" Nagel . . . did you help with evacuation during Pinatubo? I recall you were near by and participated in some way . . .

PO1 William "Chip" Nagel - Excellent video (music too). Really does a good job of describing what it was like to be there. As a dilettante uncredentialed geologist being that close to an eruption is only a dream.

I only vaguely recall that eruption because it was during the first year I was learning to deal with the constant pain that would be with me for nearly 30 years, from an injury early on in the military. (I should have gone to a chiropractor initially, which could have prevented it, entirely . . . no chiropractic treatments at base VA hospitals at the time.) It was difficult to adjust to because of being aggravated by most normal movement. As a result, I truly knew very little about how devastating Pinatubo was to life in the Philippines at the time, even though I had developed a dyed in the wool interest in earning a geology degree close to two years earlier. Only later learned more about the effects on weather patterns and temperatures.
Clearly, PO1 William "Chip" Nagel your Pinatubo time and experience, and the devastation caused, will never be forgotten.
It can be mind boggling to imagine that volcanic goings on like that, all around the planet, along with less explosive eruptions like Hawaiian volcanoes - during a time that lasted for more eons than we know - created all of the oceanic and terrestrial crust on all the rocky planets; that long-term ongoing volcanism (during the Hadeon) probably changed the course of developing earliest life on the planet, caused mass extinctions of early life several times, and contributed to the type of life and ways that life eventually took hold on earth.

Remember that 2015 eruption where the ash shut down flights to Europe for a time?

Icelandic volcano's toxic gas is triple that of Europe's industry
A huge volcanic eruption in Iceland emitted on average three times as much of a toxic gas as all European industry combined, a study has revealed. Discharge of lava from the eruption at Bárðarbunga volcano released a huge mass -- up to 120,000 tonnes per day -- of sulphur dioxide gas, which can cause acid rain and respiratory problems.
