Dike intrusion in Askja volcano

Today (14.12.2012) around 12:00 UTC Askja volcano had dike intrusion. This dike intrusion was not in the main volcano it self. But a good distance away from it. But this is in a area that has erupted before in distant past in a fissure style eruption (just lava, no volcano ash). What is the case now I am not sure at the moment. But this dike intrusion was at the depth of 25 to 22 km. So it has long way to go before any eruption takes place. This dike intrusion did also not show any sign of moving upwards according to Rúv News of this event.

What this means in the long term is impossible to know at this point. But this is one event in a long series of events that started in March 2010. This is going to end with a eruption. Large or small is impossible to know until it happens. What is also impossible to know is when and where such eruption might take place. As is always the case with active volcanoes. There is at least no reason to panic about this. Not now, not ever.

Donations: I am still needing donations to cover my cost of buying 3G hardware for upcoming geophone stations Böðvarshólar (total cost around 1300 DKK, or 29900 ISK). I have got some donations already. But they just cover the cost of UPS and USB card for Skeiðflöt geophone station. But I was fixing technical problems with it. Thanks for the support.

Interesting earthquake swarm in TFZ

Today (12.12.2012) there was a interesting earthquake swarm in south part of TFZ (close to a place called Ásbyrgi). This earthquake swarm did consist mostly of minor earthquakes. With magnitudes of from ML0.2 and up to magnitude ML2.6. This earthquake swarm is tectonic in nature. I do not believe it is volcanic in nature. But this earthquake swarm is inside Krafla volcano fissure swarm or TFZ-NVZ two volcanoes. I am not sure in this case here.

This earthquake swarm might not mean anything special as is. But earthquake activity in this area has been some for the past few years. But it has so far never resulted in any major events so far in this area.

TFZ earthquake swarm update on 06.12.2012

The earthquake swarm on TFZ continues to this day. It has been ongoing for more then one month already. The largest earthquake in the past few days has been a earthquake with the magnitude of ML2.7. Most other earthquakes that have been taking place are in the magnitude range of ML0.0 and up to ML2.7. Activity in this area happens with high and lows. With latest high being just few days ago. This continued earthquake activity shows that this area continues to be at risk of large earthquake.


Earthquake activity in TFZ yesterday (05.12.2012). It continues in the same area as Mb5.6 earthquake that took place on 21. October 2012. Copyright of this image belongs to Icelandic Meteorological Office.


Earthquake activity in TFZ today (06.12.2012). Not many new earthquake have taken place since yesterday (05.12.2012. Picture above). But there is regular activity in this area and that makes the earthquake swarm continuous. Copyright of this image belongs to Icelandic Meteorological Office.

Currently there are no signs that this earthquake swarm is about to end. Even if there is a drop in activity for a day or two. It continues as it has been doing since 21st October 2012. I am going to post updates on this earthquake swarm regularly. If anything major happens. I am going to post update soon as I can do so.

Bills, money problems and a headache (problems with my economics)

This December has gone down for me as the worst one for a long time now. As many of you already know. I am living on social welfare from Iceland (now this is important). Living on social welfare from Iceland means that my income is in Icelandic krona. It also means that I am subject to its exchange rate as I am living in Denmark (Danish krona). My total income in Danish krone depends entirely on the exchange that I am dealing with during the start of the month. For this December it has been awful. The exchange rate is around 22,55 ISK = 1 DKK at the moment with VISA. It got best in July, when it was 19,50 ISK = 1 DKK. This is a status that is unacceptable to me. But there is little that I can do to change it at the moment. My total income after taxes in Iceland is 153.000 ISK (6.793 DKK, €912), in December this number is 173.000 ISK (7.682 DKK, €1.031). This is not a lot when I have to pay for the rent, the bills and my current debt (that I am working on to get rid of soon as I can).

The reason why I am on social welfare is that I have aspergers syndrome. So I do not mix that well with normal, regular job. Even if I am fully able to work physically. My mind can be at different place at times. Communications and understanding can also be a challenge for at times. I do my best on this subject matters in normal life. But it might not work in a buy workplace where everything needs to just work between people smoothly. I have tried to work in such a place many years ago. It did not work and I got fired after just two weeks. I have been in temporary summers job in Iceland. But that job was cutting grass and lawns for people. But that was just during the summer and there was and never has been any career in doing that.

Writing as a job

I have since some years ago decided that my job should be in writing. The reason why I did start this blog is because I wanted to have something to do. Writing about volcanoes, earthquakes and such is something that I like doing. But the truth of the matter is that when you are writing about volcanoes it is clear that nothing is going on 98% of the time. The 2% of the time that something is going on happens every few months to years. This sadly means drop in traffic on my blog. That means less income from Google Adsense and Infolinks at the same time. The reason why I decided to have ads on this blog is to lessen my dependence of donations. I am going to keep the donation option going. Since that is what many other sites that I read do. Instead of getting rid of ads. You get a free e-book from me. Forever! Everything that I write and publish I send to you over e-mail when it is ready. You get a pdf file, since I can’t offer any other format. But it is drm-free (as all of my books are always going to be). So you can covert it to your needed format.

This brings me to my next point. I am almost finished with a short story that I started writing over 1 year ago (it takes time to write short stores and books). When it is ready. I am going to grab all those email address that I have from paypal donations and send the people how have donated to me a copy of that short story. I am going to do this every time I publish a new story or a book.

Donations help

Donations really do help me. Since the make it easier for me to pay my bills and buy food during the month. That is all there is too it. This blog is a one man project so far. So I do all the work my self. Check data, earthquakes, work on images and so on. That sometimes takes a lot of time. Work that is worth it and needed for this blog to properly explain what is going on when it comes to volcanoes in Iceland. The donations that I have got this month have helped pay for the backup power and hardware maintenance for Skeiðflöt geophone station. But I am still 1300 DKK short because of the cost of buying 3G hardware for Böðvarshólar geophone station that starts later this month. After Hvammstangi geophone station goes offline.

I thank you all for the support. I just hope that I can make it trough December without too many budget problems that I have already have. Now I just hope that I can buy the Christmas present that I want to give to my grandpa (DVB-T tuner, as Iceland is going all digital in the year 2013).

Hvammstangi geophone has been fixed

It turns out that the fault with Hvammstangi geophone station was a software issue. Not a hardware issue. I have now fixed this after instructions from the manufacturer of the hardware. This was a software bug. If this had been a hardware issue. It would have been a lot harder to fix. The Hvammstangi geophone station is now running normally. Any earthquake activity in TFZ appears best on this geophone station.

Hardware failure in Hvammstangi geophone

In accordance with rules of bad timing. The Hvammstangi geophone station has had a bad hardware failure. What exactly has failed I am not sure of yet. But currently the geophone station does not power up. So the hardware failure is most likely in the board that converts the analog signals to digital signal for the PC. I am going to make an attempt to fix this issue when I go to Iceland in December. If that is unsuccessful. I have to send the hardware to the U.S and have it fixed there. If that is the case. The Böðvarshólar geophone station won’t go online until sometimes in the year 2013. I can’t afford replacement station. I am just to broke to buy it (as always. I am too broke to do anything in reality at the moment).

This means I have no way to detect earthquakes in north Iceland at the moment. But if any large earthquakes takes place there. My geophone stations in south Iceland are going to record such earthquake to some extent.

Changes to the geophone network in December 2012

The following changes are going to be made to the geophone network in December. The Hvammstangi geophone station is being decommissioned. The hardware is going to be moved to new location. That is going to be a new geophone station called Böðvarshólar (bhr). This change costs me 29.900 ISK (182€, 1360 DKK, USD 236), plus a monthly charge of 2190 ISK for 3G connection. But I can only connect the geophone to the internet over GSM/3G in this location. Any donation to support me to cover this hardware cost is welcomed.

I am also going to do an maintenance on Skeiðflöt geophone station. A backup power is going to be added and I am going to resolve the freezing issue that I have been having with this station for some time now. This maintenance and adding a backup power to this geophone station is going to cost me 10.900 ISK (66€, 495 DKK, USD 86), any donation towards this cost is also welcomed. As backup power is needed for this location. But the electric grid in this location is for some unknown reason unstable at times. I do not know why that is. But to prevent damage to the hardware. I need to add a backup power to prevent it.

Other changes are not planned for the geophone network at present time. But I am not going to end my geophone network operations as I had originally planned in November. But the cost of running and sometimes hardware changes and maintenance for this geophone network is keeping me rather broke at the moment. Something that I am not happy with. I do have income of Google Adsense. But when traffic is low (when nothing is happening), this Google adsense income is low and is not even close enough to cover my costs at time and at times paying the bills that I need to pay. I always pay my bills on time. But sometimes that is all I do that month and nothing else.

The web page is going to move from the simnet.is address to jonfr.com address. I am going to post more details on that in January 2013. I am going to cut some minor costs with this. The savings won’t be great. But just a little bit.

So any support with donations are welcomed. As they help me keeping all this running. So I can report to all what is taking place in Iceland when it comes to volcanoes, earthquakes and general geology.

Harmonic tremor level drops in Grímsfjall volcano

During the night. Harmonic tremor levels started to drop in Grímsfjall volcano. The reason for this harmonic tremor level increase remain unknown and unclear. But no volcano related activity has been seen or recorded so far in Grímsfjall volcano.

So far Grímsfjall volcano has remained quiet during this glacier flood. With nothing suggesting that it is going to change soon. As for the glacier flood it self. According to latest news it seems to have peaked and is now dropping. But this was a small glacier flood. With just rise about 153 cm. But that is quite small compared to many older glacier floods from Grímsfjall volcano.

Unclear what is going on in Grímsfjall volcano

It is unclear what is going on in Grímsfjall volcano at this moment. Harmonic tremor level continue to rise. They are currently way above what is normal for minor glacier floods from Grímsfjall volcano. This might be a minor eruption, or it might just be glacier on the move inside caldera. Whatever it is. This is not a strong event. As it only appears so far on only one SIL station. The one located on top of Grímsfjall volcano. Other SIL stations do not show any change so far. There is no earthquake activity in Grímsfjall volcano so far following this activity.

So far nothing there is no word from Icelandic Meteorological Office on what is going on in Grímsfjall volcano. I am also uncertain what is going on in Grímsfjall volcano at present time. But I am sure that is going to get clearer in the next few hours. The harmonic tremor level appears to be continue to rise. So it might get confirmed in the next few hours if there is an eruption in Grímsfjall volcano or not.
