Today (20-August-2022) at 05:45 UTC an Mw3,2 earthquake took place in Reykjanes volcano. This is a part of a longer pattern in this volcano. This is going to end in a eruption, when that happens, is impossible to know.

This might also signal a new earthquake activity since the eruption in Meradalir valley is about to end. The situation is complex and many volcanoes that are now active on Reykjanes peninsula.

Today (19-August-2022) there hasn’t been any lava flow seen from the crater in Merdalir valley in Fagradalsfjall mountain according to University of Iceland, Earth Science on Facebook. Few splashes of lava have been seen coming from the crater. This has also been observed on web cameras watching the eruption. Harmonic tremor has also dropped considerably since yesterday (18-August-2022) and continues to drop.
When the eruption ends exactly is unclear, but it might happen in the next few days.

It has been reported in the news today (18-August-2022) at Rúv that more pulse activity has been seen. This results in lava being thrown up high in the air.
This is the same pattern as happened last year in the eruption in Geldingadalir valley. It took a while for that eruption to end and that might also be the case now.
Other than this, there have not been any other news of the eruption. There also has been interesting events out in the lava field, where the new lava is compressing the lava from 2021, resulting it being squeezed out at the edges. Since there is still flowing lava in the lava field from 2021 and that is going to be like that for many decades until this lava field cools through.

This morning on (13-August-2022) at 06:30 to 08:00 UTC there was a sharp drop in harmonic tremor activity in the eruption in Meradalir valley. What happened is unclear, since no change has so far happened on the surface. From the looks of the harmonic tremor now, it seems that it is unstable currently.

New fissures might be about to open up, this can happen both north and south of current eruption. New fissures might also open up on either side of current eruption if that is a path that the magma can take. What happens is unclear and it is impossible to know when that might happen. Depending on the were next eruption happens, might mean a lot when it comes to possible lava paths and possible road damage if lava flows over a important road on Reykjanes peninsula.

This is a short update on the eruption in Fagradalsfjall mountain in Merdalir valley. As expected there is not a lot of news in this eruption, since lava type of eruptions are normally not news heavy eruptions.
The amount of lava that is now erupting according to latest news is about 15m3/sec. This is higher than the eruption in Geldingadalir in 2021.
The lava seems to have filled up the valley the eruption started in. The floor seems to be about 10 to 30 meters high depending on location.
The crater has formed to some extend. The lava lake that remains there blocks the formation of a normal crater for now. This might change with time as the eruption continues.
Lava flow go both in south and north direction. The north lava flow goes into a smaller valley that was there. This is the long way out of the valley for now.
There is a risk that the lava flow is going to reach road 427 (Suðurstrandavegur) in few weeks time.
The risk of new eruption sites opening up remains high and that risk increases as the eruption goes on.
There is a swarm of small earthquakes that has been happening regularly since the start of the eruption in the dyke. It is unclear why that is happening.
I’ve been seeing what appears to be a lava fountain taking place in the eruption in the last few hours. This has not yet been confirmed, I have however observed this on the web cameras.
I think this is all. I hope the next update is going to be on Friday 19th August 2022 unless something major happens.

Today (9-August-2022) at 11:43 UTC an earthquake with magnitude Mw3,0 took place in Kleifarvatn lake. At the writing of this article, no other larger earthquakes have taken place. Today there has been a swarm of small earthquakes in Krýsuvík-Trölladyngja volcano and in Fagradalsfjall mountain. Some of this earthquake activity are just tectonic earthquakes, this applies mostly to earthquakes that are in Kleifarvatn lake and east of Grindavík town (might also be east of Grindavík, but I am not sure). This are because of the inflation from the dyke in Fagradalsfjalli mountain that reaches to Keilir mountain. The earthquake activity before current eruption in Fagradalsfjall mountain in Meradalir valley also caused some major fault line movements over a large area. What that is going to result in when it comes to magma movements is unclear for now.

Over the last two days there has not been any visibility on web cameras of the eruption. I am hoping that the weather might clear up later today or tomorrow but that is just wait and see. There has also been heavy rain in there and I don’t recommend that anyone going there in this weather. The area is also closed and now fines can be imposed by the police on people attempting to go there when the area is closed. Kids under the age of 12 have also been forbidden to walk to the eruption. Since the distance is 7 km one day (in total 14 km) over difficult area.

Today (7-August-2022) at 11:52 UTC an earthquake with magnitude of Mw4,1 took place just west of Keifarvatn lake. This earthquake was felt in Reykjavík.

Earthquake activity is ongoing in this area. This might be tectonic earthquakes because of pressure changes that are now taking place because of the eruption in Meradalir valley. That is however unclear in my view.
Reykjanes volcano
At 10:52 UTC an earthquake with magnitude Mw3,0 took place west of Grindavík in the Reykjanes volcano. This might not be an earthquake related to pressure changes because of the eruption in Merdadalir valley. I am however not sure if that is the case. The Reykjanes volcano is going to erupt one day, since it goes out in the ocean, an ocean eruption and island formation is a possibly. An eruption on land is also an possibility. When and how an eruption happens in Reykjanes volcano is something that just has to wait and see.
The eruption in Meradalir valley
Newest reports is that a pulsing activity has started in the largest eruption fissure in Meradalir valley. This suggest to me that the old lava that is now erupting is almost all erupted. When that magma supply is gone a short break in the eruption might happen and then a new, larger eruption is going to start with the new magma that is on the way to the Fagradalsfjall mountain. When and if this happens like this is a big wait and see.

This is a short update because not much has changed in the last 24 hours in the eruption in Meradalir valley in Fagradalsfjall mountain.
The eruption is now in 120 meter long eruption fissure. Currently the output of the eruption is around 18 m3/sec according to yesterday’s measurements.
The new lava has now flowed over the lava from last year (2021) and into eastern Meradalir. This is about 1 km distance that river of lava has flowed. Image of that can be found here on Facebook.
According to chemical analyse of the magma. This is the same magma that was erupting when the eruption in the older crater stopped erupting in September. This shows that this magma is older and the new magma has not yet reached the surface.
Fissures on the ground north-east of the eruption site have started to move and getting wider according to experts that are in the area. This strongly suggests that an eruption is about to happen soon in that location. When it starts is impossible to know. But this is going to close one way to the eruption and if eruption starts in new location south of the crater, seeing and viewing this eruption might start to get difficult or impossible, at least the part in Meradalir were the current eruption is happening now.
I think that is all for this Friday. Next update is going to be on Friday 12-August unless something major happens in this eruption and that might just happen.

This is a short update on Meradalir valley/Fagradalsfjall mountain eruption at 21:25 UTC on 3-August-2022.
Most of the fissure that started erupting at 13:16 UTC in Meradalir valley, just north of the old crater in Geldingadalir in Fagradalsfjalli mountain (Icelandic location names are long) is active after few hours of activity. Earthquake activity is now slowing or stopping almost completely as is the same thing that happened in 2021 after the Fagradalsfjall mountain / Geldingadalir valley eruption started.
The most northern part of the eruption fissure already seems to be shutting down. How fast that happens I don’t know, but there seems to be a crater started to form at the south end of the eruption fissure. At least for now. The news report at Rúv today noted that people where walking over a patch of land that was releasing gas and thermal camera showed the ground to be warmer than normally. This strongly suggests that an eruption might start at those location without warning. I don’t know exactly where those locations are, but they must be in the walking path, placing them south of the 2021 eruption crater.

Today (03-August-2022) at around 13:30 UTC an eruption started in Fagradalsfjall mountain, just north of the eruption site that took place in March to September 2021. The fissure that is now erupting is growing both to south and north. That suggest that the power of the eruption is currently growing.
This is all the information I have at the moment. This eruption is clearly visible on the web cameras that mbl.is has on YouTube, along with web camera from Rúv.
I’ll post new information when I get them. I don’t know when that is going to be.
