Quiet time continues in Iceland geology

It has been rather quiet in Iceland during past few weeks. This seems to be continuing to some extent. There are few earthquakes and nothing noticeable is taking place in Icelandic volcanoes at the moment. While this quiet time is currently I am going to enjoy the summer a little bit. I am also trying to survive the heatwave that has been taking place in Denmark + Northern Europe for the past 10 days. As currently I am not used to type of heat (over 25C). But that is going to take some time until I do.

I am going to try and write something while it is quiet in Iceland. But this quiet time is going to mean longer time between blog posts. But I am sure that something of interest is going to happen soon in Iceland.

Quiet period ongoing in geology, except in current erupting volcanoes

Everything seems to be quiet in Iceland and around the world. Nothing major is taking place in regards to earthquakes or volcano activity. So I do not have a lot to report on at current time. If this quiet period continues I am going to write about something in Iceland geological history that I know of. Nothing long, just short and as detailed as I can make it.

Last week volcano activity

I hope to have more to write on soon. But it is hard to know for how long this quiet time is going to continue.

All quiet in Iceland volcanoes and earthquakes

Currently everything is quiet in Iceland. Most of this quietness is mostly due the winter storms that are passing over Iceland at the moment. When this changes I have no idea. But there are always several weeks during the year that are quiet in Iceland, both in activity in volcanoes and earthquakes.

This is the reason why I have not had so much to write about during the past few days and weeks. But it can’t be helped. Activity in the world also seems to be rather quiet, there are always earthquakes but most of them are small.

I also advice any tourist going to Iceland this time of year NOT to go up on volcanoes during the winter without experienced mountain travel guide. If you do that without an guide you are risking your own life, as the weather in Iceland is unforgiving and has killed people in matters of hours. The people in the news on Rúv got really, really lucky. The where just cold and where saved by rescue teams.

Activity remains low in Iceland. Eruption continues in El Hierro volcano

At the present time the earthquake activity remains low in Iceland. This goes for both Katla volcano and other areas of Iceland. This is the regular quiet time in Iceland, as it happens sometimes. For the next days, there is a risk of frost-quakes as the ground freezes over in a cold snap.

El Hierro volcano, Canary Islands

The eruption in El Hierro volcano continues as before. New eruption vents have been opening up at random in the south part of El Hierro volcano. Earthquake activity to the north has dropped. While at the same time, the earthquake activity seems to have increased slightly to the west part of El Hierro volcano. I am not sure why that is yet.

In the tremor data. I have been seeing several explosions taking place. But they create a spikes in the tremor plot, that is different then what happens when a earthquake takes place.


The current harmonic tremor from El Hierro volcano. Explosions are the spike activity (30 November, 2011). Some of this however might be sudden increase in eruption activity. Copyright of this picture belongs to IGN (Instituto Geográfico Nacional).

Other then that. The eruption in El Hierro volcano seems to be about the same for the moment as it has been for the past almost two months now. So far it is impossible to know when this eruptions ends. But eruption in La Palma volcano lasted about one month on average. Eruptions in Lanzarote volcano have lasted about three months (last eruption was in the year 1824). Based on this. This might be a eruption that lasts for about 3 to 5 months at the longest in my opinion. But what actually happens is just something that is a wait and see matter.

Update on the weekend activity

Iceland

This weekend was quiet in Iceland. There was almost nothing going on. There was only one small earthquake swarm in Krýsuvík volcano. But this earthquake swarm was tectonic in nature, not volcanic. The largest earthquake in this earthquake swarm was about ML3.2 in size. Few earthquakes where in Katla volcano, but less this weekend then many others. But it is normal for Katla volcano to be quiet during November to March each year due to snow that is added to the glacier. But that increased the pressure of the glacier on top of the magma chamber (floating balance laws at work here).

Mainland Spain

There was a flurry of earthquakes on Mainland Spain during the weekend. None of this earthquakes where felt, from what I can gather at IGN web site.

Canary Islands, Spain

The eruption at El Hierro volcano continues as it has done for the past almost two months now. The harmonic levels are about the same as it has been, but there seems to be minor intermittent in activity from El Hierro volcano. IGN has setup a picture web site with images that show the activity since this eruption started clearly.

Erik at Eruption blog has good blog post about the magma mixing that appears to be taking place in the eruption in El Hierro volcano.

Other then this. Is is all quiet in Iceland for the moment. But frost-quakes should be expected in the next 48 hours or so in Iceland. As the ground freezes over in a really cold weather.

Bogus news story going around about Katla volcano

There is a bogus news story about Katla volcano. The bogus news are that Katla volcano is just few days from erupting. This is wrong. At the moment there are no signs that Katla volcano is about to erupt. There is currently a relative quiet in Katla volcano, compared to the activity several weeks ago. But that activity started after the minor eruption in Katla volcano in July 2011 (this summer). This bogus news is also annoying the staff at Iceland Met Office, how are now getting phone calls about this news. Where other professionals are trying to get more information on this or just trying to figure out if the news is correct or not.

For the moment, it is all quiet in Katla volcano. If there are any changes. I am sure to write about it here with up to date information on what is going on. While the Yellow Press is looking for big-foot or something. So once again, the yellow press has it wrong and spreads minor panic following this poor news reporting.

Quiet time in Iceland in earthquake and volcano activity

Currently there is a quiet time taking place in Iceland. This does happen often in Iceland. Sometimes the quiet days are due to bad weather. But now the quiet seems to be a ongoing and has been for past few weeks. The exeption from that is the earthquake activity in Katla volcano and the man made earthquake activity in Hengill volcano. But that activity has dropped down for some reason the past few weeks. I am not sure why that is.

I also want to point people to a new feature on Iceland Metrological Office web site, that seems to have gone up only few days ago. But this web site shows the drumplot (webicorders) from the SIL network. This is not far from what my geophone network shows. That web site can be viwed here.

Blog post updated at 16:43 UTC.

Back to Denmark in the summer of the year 2012 (off-topic blog post)

This is a off-topic post. So feel free with off-topics thing in the comments.

One of the aspect about writing about volcanoes is that it depends on how you feel in the place that you write in. But for me as a writer that is a important aspect of my writing. I love writing about volcanoes and earthquakes, the monitoring data among other other things all related to volcanoes and earthquakes. But that is also important for me to live in the correct place so I can make my best work. This is not just about writing about volcanoes, but this is also important for my other book work that I am planning to write in the future.

The thing is however that place for me is not Iceland and never has been. It is a collection of many social factors I am not going to go into here in details, but the biggest reason is that in Icelandic culture writer are not appreciated as they should be on the public scene (and some types of work are not even put forward unless you got right connection). But I find that living in Iceland affects my work and even starts a writing block with me. For that reason it is important for me to do my work elsewhere then in Iceland. From what I gather my writing appears to work well in Denmark. It might also do so in other Europe countries. But so far my feeling for Denmark is good and for the moment I am going to stick with it.

For that reason I am moving back to Denmark in the year 2012. The exact date is not yet clear. But I have decided that I am hopefully going to move in June. At the moment that might change. But I find this to be a good target, as then I have been one year from Denmark since I did move first time around to Denmark in February in the year 2011 and back to Iceland in June.

I am plan moving to a town named Ringsted in Denmark. It is closer to Copenhagen then Sønderborg where I used to live. But trip with a train is about 35 min, rather then 3 hours and around 30 mins from Sønderborg. Around the time that I move. I plan to have for all the costs that I need to pay. Thanks to a computer work that I got. I should already have been covered the transport cost already (I have not yet been paid, so this is in the remains to be seen stage). The only thing that remains is the deposit for the apartment plus one expensive month without rental benefits in Denmark (since I am low income).

Status update to my blogs

In light of all this. I have decided that I am going to upgrade the status of my blogs to work, rather then just plain hobby. It is going into to effect from this blog post here in part. But it is going to full effect from 1. January 2012. How this is going to develop is a process that I am going work on all the time that I am going to write. But the average work on a blog post that I write here is about 1 hour and 35 min. But longer blog post can take up to 8 hours to write from start to finish.

This change suggests that I am going to have some income from this. That would be welcomed. But for the moment I do not have a lot of income from this work. Most of the income is from donations and advertisements on this web site. For the moment, that is not enough for the whole month. But with the social welfare it helps. But that also has its drawbacks for the long term. As income lowers my social welfare if it goes above certain amount. Now, that is all good with me if that income would be constant. For the moment, that is not the case. So how this is going to turn out is a good question. But I hope for the best when the time comes. For the moment however, my income from this is low and I expect it is going to remain so for the months ahead.

As for my plan on paying back my debt with the bank. It is going rather good. But it is going to go better next month, as I am only going to school this autumn. So I am hoping to be debt free before the new year comes. But if that happens remains to be seen.

On-topic snapshot

It is all quiet in Iceland. While that remains. I am writing this blog post to use the quiet time for something useful.

Thanks everyone for the support! 🙂

Currently all is quiet in Iceland

At the moment it is rather quiet in Iceland in earthquakes and volcanoes. When that might change is impossible to say. But in the last few days there have been minor earthquake swarms on the Reykjanes Ridge. It is not related to volcanism, but rather tectonic movement along the rift zone.

There is continued minor earthquake swarm activity in Katla volcano. But it has quieted down from about two weeks ago. For the moment, the glacier floods seems to have stopped.

Other then this minor earthquake activity, everything is quiet in Iceland.

Overview of current events in Katla volcano and current status

Here is an overview of the current events in Katla volcano. This is the short version, as I have not had the time to go over all the data collected so far.

12 June: On this day I did notice the first harmonic tremor spikes. This tremor spike was small and only noticed on few SIL stations around Mýrdalsjökull volcano. No earthquake activity was detected following this event. At least no earthquake activity that was unusual in my opinion.

17 to 18 June: The first earthquake swarm took place on this day that I connect to the current events. This earthquake swarm was special and different from the normal earthquakes that I see in Mýrdalsjökull volcano caldera. It was how dense this earthquake swarm was. There was no or little harmonic tremor following this earthquake swarm.

21 June: New harmonic tremor spike took place in Katla volcano on this day. It was a bit stronger then the first one. But lot smaller then what did happen this weekend.

28 June: What appears as an glacier earthquakes did appear on this day. Along with normal earthquake activity inside the Katla volcano caldera.

After this the events of July 8 start, it did end on the 9 July after what is most likely an minor eruption inside the Katla volcano caldera. This event is over it seems and Katla volcano has once again paused. But that has happened repeatedly over the past few weeks. The time between stops is different and it is impossible to know when the current pause ends. It is also impossible to know what happens next time activity picks up in Katla volcano caldera. Currently the earthquake activity continues in the Katla volcano caldera, but there are few earthquakes happening now then earlier this weekend.

For now all that can be done is to wait and see what happens.
