Earthquakes north of Kolbeinsey Island

Send to Kindle

Today (16-March-2016) there was an earthquake swarm around 110 km north of Kolbeinsey Island. At this location there are no registered or known volcanoes, there however might be one, but it is difficult to confirm. This earthquake activity however appears to be related to an rift valley that is at this location, rather then any volcano activity.

Largest earthquake in this swarm had the magnitude of 3,1. That magnitude is possibly an underestimate of magnitude due to distance from the SIL network. Other earthquakes have been smaller, but one earthquake had the magnitude of 2,9. That earthquake might have had a magnitude above 3,0 in reality. I suspect more earthquake activity has taken place without being detected by the SIL network.

Deep earthquakes in Askja volcano (15-March-2016)

Send to Kindle

Yesterday (15-March-2016) an earthquake swarm took place in Askja volcano. This was an deep earthquake swarm, with deepest earthquake having the depth of 18,7 km and the shallowest earthquake with the depth of 14,9 km. The earthquake swarm took place inside the volcano and there are clues that suggest it has it’s origin. This has been happening regularly since 2010 and after the Bárðarbunga volcano dyke getting close to the main magma chamber in Askja volcano the activity has slowly been increasing. This activity is not above background levels and nothing suggests that an eruption is about to happen any time soon.

For the moment the progress and the change in Askja volcano is slow, but that might change if the magma inside the system finds a pathway to the surface. If an eruption does happen I’m not expecting anything big, just a lava eruption that is going to go on for few days to weeks. Unless the magma gets into contact with water, creating a short term explosions. This is only a speculation, but Askja volcano is an active system and as such anything should be expected from it.

Weather warning for South to North Iceland

Send to Kindle

Tomorrow (Sunday 13-March-2016) extremely bad weather is expected on south to north Iceland. The weather is also not going to be good in other parts of Iceland, but it is going to be far worse in south Iceland, western Iceland and north-western Iceland. With wind reaching 32m/s (115km/h) and with far stronger wind gusts. Today the weather has also not been good, but tomorrow it is going to be worse. Roads are going to get closed, as did happen today (12-March-2016). If you are in Iceland follow the closures since in this type of weather a rescue mission might not be possible due the the weather. The rescue crews might not even attempt reaching stuck people if it comes down to it. Since this strong wind is going to be followed by a warm weather and heavy snow melt at the same time, there is a risk of local floods in the next 24 hours.

Its going to be bad weather tomorrow. Follow the advice given in this weather. Copyright of this image belongs to Iceland Met Office.

This is only the weather forecast today. Tomorrow might get a lot worse if the weather forecast is off, that often happens in Iceland due to random factors of nature.

Still mostly quiet in Iceland

Send to Kindle

Today (10-March-2016) an magnitude 3,2 earthquake took place in Bárðarbunga volcano. The location of the earthquake swarm was in the caldera, with the location of the 3,2 magnitude earthquake being in the North-east part of the caldera.

The depth of this earthquake swarm was shallowest at 0,1 km, but most depth was 8,6 km. No other change has been observed in Bárðarbunga volcano so far. Other than this minor activity today in Bárðarbunga volcano activity remains low in Iceland. Currently there are storms passing over Iceland, that reduces the sensitivity of the SIL network.

Donations

Please remember to support my work with donations. I’m getting rather broke at this moment. This will get better with time. That I’m sure of. But that moment I’m in minor problems and any help is welcomed. Thanks for the support. 🙂

Quiet in Iceland at the moment

Send to Kindle

For the past few days it has been quiet in Iceland when it comes to earthquakes and volcano activity. Quiet period happens, they are usually followed by a spike in activity somewhere in Iceland.

For those wanting to pass the time while it is quiet. I suggest a message in a bottle website that Rúv put on, as part of a science show for kids they had on the schedule this winter. It’s updated several times a day when the bottles send a message to a passing satellite.

Possible confirmation of minor eruption in Hamarinn volcano in July 2011

Send to Kindle

In July-2011 a minor eruption took place in Hamarinn volcano (part of Bárðarbunga volcano system). For a long time I’ve thought that those events in Hamarinn volcano where an eruption, rather than anything else. Due to how the glacier flood appeared and how sudden this all thing did happen.

Today (05-March-2016) Stöð 2 (Channel 2) ran a small news segment about this and the possible confirmation of this minor eruption in Hamarinn volcano in July-2011. I have the same view on the minor eruption in Katla volcano that same month. Its the view of Magnús Tumi, professor in geology that the events in Katla volcano where due to hydrothermal activity, not a minor eruption. I disagree with his assessment on what did happen in Katla volcano that summer. The top flood from Hamarinn volcano in July-2011 was 2.200m³/sec.

The articles I wrote about the events in Hamarinn volcano can be found here.
New harmonic tremor detected. But it is not from Katla volcano
Glacier flood confirmed from Vatnajökull glacier, flood is from Hamarinn volcano (Loki-Fögrufjöll area)

Earthquake swarm far north of Kolbeinsey Island

Send to Kindle

Today (5-March-2016) an earthquake swarm place took place around 190 km north of Kolbeinsey Island. Two largest earthquakes detected had the magnitude of 3,3. Other earthquakes where smaller in magnitude. Due to distance exact location is difficult to confirm, along with exact magnitude. This earthquake activity did not appear on EMSC seismic network.

At this location there might be a volcano, it is unconfirmed at the moment. Last eruption is suspected to have taken place between 1997 or 1998. This volcano doesn’t have any name that I know of.

Four minor eruptions took place in Bárðarbunga volcano in August-2014

Send to Kindle

In Stöð 2 (Channel 2) news this evening was a short news segment about four minor eruptions that took place in the time between the dyke intrusion starting (16-August-2014) in Bárðarbunga volcano and until the eruption in Holuhraun (second link here) started (29-August-2014). The second small Holuhraun eruption, that lasted only for few hours (link 1 here [images, 2014], second link here [images, 2014]).

Those eruptions where small, didn’t break the glacier surface, but they did create small cauldrons. Three of those eruptions took place above the dyke on its path to Holuhraun eruption site. One of the eruption took place in side of Bárðarbunga volcano, south of the caldera (red circles on the map in the news). The mystery of what happened to all the melt-water has been mostly solved. Following this eruptions a rift episode took place (ongoing) and that formed cracks in the surface, allowing the water to go underground and not flowing into the nearby glacier rivers.

Magnús Tumi, the geologist spoken with at Earth Science at University of Iceland doesn’t think Bárðarbunga volcano is preparing for a new eruption. I disagree with his assessment. I base my assessment on earlier documented history, far as that goes and also the fact that rifting is currently taking place in this area and such events never do things quietly, even if no eruption happens, earthquakes do (and a lot of them).

Earthquake swarm in Bárðarbunga volcano (Week 09)

Send to Kindle

Bárðarbunga volcano continues it earthquake activity and it has now been a year since the eruption in Bárðarbunga volcano ended in Holuhraun (article I wrote about it can be found here). This activity (image) took place on 2-March-2016.

160302_2155

Largest earthquakes in this swarm had the magnitude of 3,1, 3,3 and 3,6. Other earthquakes where smaller in magnitude. The reason for this earthquake swarm seems to be a developing weakness in the north and western part of the caldera. Activity in south part of the caldera seems to be crust adjustment to this weakness (stress changes). The weakest area is long one (I didn’t find information on how large the caldera is, but it is large). This weakness is going to continue to develop until an eruption happens or the magma finds it self a new path and that is more likely than an eruption taking place in the caldera rim, however I cannot rule out an eruption in the caldera at this point. This is all just wait and see situation at the moment. Interesting earthquake also took place in Hamarinn volcano, it had the depth of 13 km and magnitude of 0,7.

Deep earthquakes also took place in Tungnafellsjökull volcano. That earthquake had the magnitude of 0,8 but depth of 17,9 km. Suggesting that some stress changes at depth are taking place. In this case I doubt magma created the earthquake.

If an ash eruptions takes place in Bárðarbunga volcano, the resulting ash fall would be devastating (besides the following glacier flood). Last time larger eruption took place in 1477 half of Iceland got covered in volcano ash (that’s 50% of land), the volcano ash eruption in 1711 covered north Iceland and large parts of east Iceland. In 1711 to 1729 total of nine glacier floods took place and the source of them is believed to be Bárðarbunga volcano. Glacier floods from other volcanoes (Grímsfjall, Kverkfjöll, Þórðarhyrna, Hamarinn) are also highly dangerous. The volcano ash had thickness up to 100 meters next to the eruption area in 1477 (see map in link 1).

Please remember to support my work (donations for March specially needed)

Send to Kindle

I put a lot of work into this website. It mostly happens when something is going on in Iceland, earthquake swarm or an eruption. But between those times things are quiet in Iceland the traffic to this website drops down to few thousands of page views a day.

Donations needed for March

I was hoping to keep things decent in March, but that didn’t work out properly since things cost in Iceland. I am also trying to save for transport cost of my belongings back to Denmark from Iceland. I say trying because I don’t think its going well at the moment. Money wise I hope that things are getting better for me, at least part of my debt is getting lower at the moment, while I had to increase it other areas (a little, not a big problem in the long run). My biggest problem in past few days is the fact my computer died and I had to replace it (I just buy the motherboard, cpu, memory and video card. I also had to buy new dvd drive, old one had died last summer). That was expensive, even if I choose as cheap computer parts as possible, leaving me with a budget hole unexpectedly when it comes to my transport costs of my belonging. I’m now trying to figure out a way to cover the transport costs without any problem. It is going to be a tricky thing to do on my low income, but I think its mostly doable. Any support in that direction is welcomed, along with support to help me survive March without running out money for food (since I really dislike using my savings for food).

I wish my financial situation was better then it currently is. I’ve been trying to make progress and I have made progress, but it is slow, but improvements are being made. Once I’m back in Denmark the financial situation is going to remain a little difficult, but it is going to improve with time and effort on my part to improve it. The thing also is that many websites and youtube channels ask for donations (many also have sponsors) so they can make more content for people to watch. When I write about earthquake swarms, or the latest activity in volcanoes in Iceland, or posting updates every hour or two when an eruption takes place (that is hard work).

Plans in the works

I am looking into that to create a website about technology. That would cover computers (PC), mobile phones, televisions and other thoughts on that matter. Currently I am only looking into it to see if that pays off, or if I should find something else to write about when things are quiet in Iceland. Increasing my range might increase my income (maybe not). Since I am also good with technology of all types and size, since I’ve been doing that for as long as I’ve been working and thinking about earthquakes and volcanoes.

Book writing

I am also going to continue to write books and short stories. Since I just can’t be without it. I’m not sure when next short story comes out on Amazon, but I am working on few stories, both short and long in my head.

Moving back to Denmark

I’ll be moving back to Denmark on 14th April. That makes me happy. More details on this later. The Bov geophone station is going to start operation soon after 14th April, not sure on exact dates at the moment.
