Ahh, I was mistaken. Libre is open source.

Having used autocad for nearly 40 years, I will say they stick it to their customers pretty fiercely. I still use 2010 with 3rd party software to get it to run on win10 at home. I do a lot of solid models and assemblies as well as technical 2D drawings and renderings.
FreeCAD is impressive, but it lacks an easy to use interface. NanoCAD and LibreCAD are not open source but are free and are both better 2D alternatives.
Edit: LibreCAD is open source.
They trip all over themselves just to seemingly not use the phrase "open source" huh?
Professional geologist Shawn Willsey posted a graphic of the approximate location of the newest fissure on his livestream. This fissure and flow is not likely to be a threat to the town of Grindavik, but it is a threat to both the blue lagoon and the powerplant.
I built a PC for my little sister in 2007. She was starting college and didn't have a computer. It totaled 2805 and some change, custom built through Antares Digital (When you know, you Lili). These were all top of the line components (Asus M2N32-WS PRO, Amd athlon64 X2 AM2 5200, Corsair Memory). Not a cheapy system in its day.
Three nights before I was to deliver it to her, I completed all of the setup, had all the software ready to go, even setting up a custom theme for her (We were both metalheads). My folks said that she would need a printer/fax/copy/scanner as well, so last minute, I ended up buying an HP 5610 at target for 192 dollars.
The HP instructions didn't say that if you connected the cable between the printer and the PC before you had installed the drivers, the printer would not mount as a device. In fact, it would never connect to that PC ever again. Apparently, it ruined the registry until you reformatted and reinstalled the OS.
To be fair, the manual did say to install the drivers first, then the cable, but this was not the norm back then and they didn't really emphasize it in any way, nor did it mention that you were about to be FITA big time. Had to scramble to completely reformat the drive, reinstall all the software... Essentially, starting over from a blank slate and getting done in 2 days for delivery to her dorm on move in day. It did connect second time around.
I wrote them an angry letter regarding the poor deployment, but of course I never heard back from them. Never bought another HP for myself or anyone else ever again. I go out of my way to encourage people to not buy anything from HP. If I happen to be somewhere and see someone looking at an HP printer, I'll just approach them, introduce myself, and tell them my story to discourage them from buying it.
The aftermath of the January 14 2024 volcanic eruption which has now officially been declared to be over.
The Map
This is a combination of Agust Gudmundsson's Satellite Map and the 2D quake map. I used Autocad to import each image and then known features to match the scales and orientations, but it's still an approximation. Additionally, the satellite image is greyscale and low resolution so the perimeter of the lava field gets hard to discern in some areas with little to no color contrast.
The Fissures and Lava Fields
The two eruptive fissures (north[900m] and south[150m]) are shown in red. It ejected quite a bit of lava, but the experts say they were lucky that the eruption was as weak as it was. The new lava fields from each are in orange. The initial fissure to the north grew in its size as the eruption continued and extended itself underneath the original berm. This extension and the area where the berm crossed the highway allowed lava behind the ber.
The southern fissure was completely unexpected and it was heartbreaking to witness. While it released a smaller amount of lava at a lower pressure than the north, but due to its proximity to the village, it was enough to destroy at least (2) homes.
The Berms
The berms are shown in blue, both the original (lite blue) and the two new additional ones (medium blue).
The original 10-15 meter high [32-48 foot] berm held up strong and most likely saved the village from much more damage. However, it was not completely effective. A small portion of the berm at the highway had been left open for travel until the day of the eruption when emergency crews plugged it last minute.
During and since the eruption, the emergency crews have built (2) new berms on the west side of Grindavik to further deflect lava and protect the village.
The Infrastructure
The town is still under evacuation order due to the uncertainty of future eruptions and the dangers inside the village due to subsidence and instability.
Electricity seems to be back on in town.
The geothermal pipeline that runs tandem (a few meters west) to the north-to-south highway and was destroyed by lava. This is significant in that this supplies Grindavik it's most abundant heat source, hot water. Homes that were not in harms way are still going to have moderate damage due to frozen pipes. [Edit Jan 21 2024] It was reported that just yesterday emergency crews bypassed the destroyed section of pipe restoring water both hot and cold.
Two of the reported three homes that were destroyed by lava are shown in white. The north home does not appear on many maps. It was reported to be a new home that was yet unoccupied. The south home was occupied and appeared to be a complete loss. I am still unsure about the third home.
The greenhouse, shown in green, survived seemingly undamaged thanks the the original berm. It was reported to have had all of its equipment removed prior to the eruption.
I heard a report that the local government is probably going to be able to offer Grindavik residents a buyout for their homes and property but all I can find is a report that it may be possible.
250 abandoned sheep were reported to have been rescued and removed on Tuesday Jan 16.
The Next Chapter
The future of Grindavik is not looking so good. The data seems to point towards yet another eruption, and likely within the next few weeks.
The Svartsengi GPS Station is near the power plant (north of Grindavik). This is the region where the experts suspect the ultimate source of the magma. It is feeding the magma chamber under Grindavik which is where the eruptive fissures from both December and January formed. It will take months or years of inactivity for this to cool and plug itself. While the system is fed, the pressure will increase. As the pressure builds, the chances of the magma moving or erupting increase. There is no real way known to man as to what exactly is going on down there.
Earthquakes have been very quiet in the area which is to be expected after the balance of pressure. They have ramped back up through the week but are still low in frequency, size and depth. During the eruption, there were numerous mini-clusters of earthquakes near Grindavik (Locations with a high concentration of earthquakes). One of these locations ultimately became where the southern fissure erupted. There were (2) other mini-clusters south of that fissure well inside of Grindavik. Both of these areas of mini-clusters are above the magma chamber and could be places of a future eruption. With the damage to the area, it could just be stress related fractures.
Send hope and prayers to the great and brave people of Grindavik.
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.
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.
I look at the most recent activity and suspect that either a new fissure has opened in the town proper or the southern fissure has lengthened. There exists a mini cluster of larger earthquakes in this area. The best case scenario is that this is a new structure on fire. All three scenarios are rotten-a-f. It is getting hard to tell due to gasses, smoke and darkness.
That is most likely a RUV news helicopter in the foreground. It's footage may be available shorty. You can also read their english blog here. Drones are once again banned 4km from town.
Iceland erupted again this morning at 7:57am Grindavik Time. The eruption was captured in real time. It again is a northwest linear fissure and is located west of Hagafell and a bit south of the prior eruption site in December.
While the locals had built a huge rock berm to protect some of it's infrastructure, the fissure formed and spread underneath the berm, circumventing its protection. Everyone has been evacuated, though there are reports that despite being told not to bring any previously evacuated animals back to town, some may not have obeyed and now the animals may be locked up and in harms way.
Additionally, a second fissure opened on the north edge of town. You can see this in real time on Professor Shawn Willsey's live update from early this morning. This southern fissure is much smaller but is much closer to town. It has spewed forth enough lava that it has now contacted and destroyed (2) houses along the towns northern edge. It was one of the worst scenarios that could happen. This is likely just the beginning, and could signal the end of Grindavik as it now exists.
The northern fissure has ejected a huge amount of lava but most was deflected and contained by the berm. It has now breached the berm at the highway, which they plugged as best they could early this morning. All things considered, it was quite wise of them to do this. The greenhouse would likely have been destroyed already, and much more lava would now be heading towards Grindavik, which is downhill from both eruption sites.

This is a very serious and dire situation. Whatever god you acknowledge, pray for the town of Grindavik to be spared. My heart goes out to the brave people of Grindavik.
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.
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.
