The magma chamber threatening the grindavik area has erupted again just before 8:00am.

A map plotting the 569 earthquakes (and still counting over the last 24 hours). These are mostly centered around the magma intrusion.
A close up view frown Professor Shawn Willsey’s livestream showing just how close the southern fissure is to town. This was taken a few hours ago via ariel drone. The vent opened in real time while the drone was flying and observing the northern rift.
A few hours later, a structure in northern Grindavik closest to the southern fissure appears to have caught on fire.
If there is any good news to be found, the eruption appears to have lost a bit of its initial thunder.
A closer view of the initial damage. This could very well be the beginning of the end for Grindavik.
It noteworthy to mention that the town has been evacuated and the people are not in harms way, but this was likely someones home. My heart breaks for you folk.
At 7:57am, the fissure opened. Whereas last time the fissure opened up far to the north and east of Grindavik, they were not so lucky this time. The fissure has now spread much more south in the Hagafell region. It seemed to me as though it erupted at the southern end of the fissure that erupted in December. At the time of this post (11:00am), magma is only a few hundred feet from the greenhouse and maybe a mile from Grindavik.
A considerable portion of the rift spread under the protective berm they created over the last few weeks. While the berm was effective (Think sandbags stacked up to stop flood waters, but with dirt and stone), It could only ever stop a certain amount of liquid flow. This spreading of the fissure effectively circumvented it’s protection for areas of the fissure inside the berm. The best case scenario now is that the southern end of the fissure ceases and cools before it can eject enough matter to overwhelm the town, which is now downhill.
Send hope that Grindavik and it’s populace are spared. This is close to a worst case scenario.

What’s home insurance like in Iceland?
Not sure, but I suspect rates just went up. I’m just a science geek from North Carolina that does refractory for a living, hence my interest.
I watched as the first home caught fire. It was brutal to watch it. I did read that it was not occupied. It does not appear on a lot of maps. The second home though that went up was occupied. This was someone’s home, someone’s place of solace. Children were raised here. Memories were rooted here. It was a total loss. I read that (3) homes in total were destroyed by fire due to the 100km southern fissure’s lava output, though I only saw (2). I am unsure about the third. I am unsure where the third one was.
Numerous other homes are going to be severely damaged though. Hot water is actually quite abundant I hear due to the geothermal power plant. The lavaflow from the 900km main fissure was mostly deflected by the berm away from Grindavik, but the berm untimately guided it to the pipeline. Geographically speaking and considering the timeframe they had to work in, I don’t think it could be helped.
I understand that hot water is a primary source of heat since it’s a cheap and abundant byproduct of the powerplant. It’s what you’re also bathing in at the Blue Lagoon Hot Springs. Now devoid of heat, I would suspect that many homes are now going to suffer damage from frozen/busted pipes.
My heart still goes out to the incredible people of Iceland. I’d like to think I could cope with an event like this, but I’m fairly certain I would puss out. Icelanders are far more metal than I.
Interesting, I didn’t think about what for of chaos a disruption to a major geothermal pipe could cause.
Luckily, Icelanders is pretty good about keeping people alive during events like these.
My two was hit hard by the Thomas Fores, and while mine didn’t burn down, I know people who lost their homes to that fire. It’s pretty devastating, but they’re all doing well now. I hope it’s the same for these people.
Either a third fissure has opened (there is a mini-cluster of larger magnitude quakes in his area), the second fissure has extended into town, or more homes are catching on fire. It’s getting hard to tell which due to the volcanic gasses (White), smoke (Black) and just the darkness of winter.
There was a another mini-cluster of earthquakes further to the south edge of town as well. With it’s proximity to the sea it will cause a severe amount of damage.
I feel this is a historic event. I’m also a refractory designer, which places this squarely in my realm of interest, but it’s heartbreaking to have to watch in slow motion. This would be very cool if it were not for the human element present in these conditions.
If you are looking at camera 4 (yellow), the camera is situated atop porbjorn looking west and a bit south. The red lines are an approximation of the rift. The building near center frame becoming surrounded by lava is their greenhouse. Town is at the right.
Edit: My line is drawn incorrectly. It is a bit more west on the other side of Hagafell.
