Magnitude 4,4 earthquake in Bárðarbunga volcano

Send to Kindle

Today (20-May-2016) a magnitude 4,4 earthquake took place in Bárðarbunga volcano. This is the strongest earthquake so far since the end of the eruption in February-2015. This earthquake swarm also had two magnitude 3,3 earthquakes. Other earthquakes where smaller in magnitude.

Official statement from Iceland Met Office is that they are not sure what is going on. What is clear is that seismic energy being released from Bárðarbunga volcano has increased a lot since end of the eruption in February-2015 and current GPS data suggest rapid inflation. Both of are unusual after caldera collapse like Bárðarbunga volcano experienced in the 2014 – 2015 eruption. Due to lack of historical data it is hard to know for sure what is going on, whatever it is, it’s the first ever that is being monitored in great details.

Current events have not lead to an eruption so far. They however might do so in the future, when is difficult to know since the time frame of this development is unknown, it might be hours, it might be decades. Satellite images also show that cauldrons that have formed at the edge of the caldera are getting deeper and possibly larger, suggesting an increased hydrothermal energy at the locations where they have formed. This suggest that more magma is collecting at depth in the caldera, something as sad above is highly unusual due the recent caldera collapse in the last eruption. I’m expecting more earthquake swarms like this and growing magnitude of the earthquakes that take place. The weekly pattern is going to continue and I suspect it might increase soon, when is impossible to know for sure.

Donations

Please remember to support my work with donations (or by using Amazon). Currently my financial status is not so good (worse then what I was expecting). It will get better, just takes few months and I need to survive those months. Thanks for the help. 🙂

Earthquake activity in Bárðarbunga, Öræfajökull, Langjökull north volcanos

Send to Kindle

This is going to be a little compressed article. Since I’m currently in Iceland. I’ll be back in Denmark on 18-May. No GVP links now. I don’t think that my laptop can handle it (its slowly turning into non-functional computer).

Bárðarbunga volcano

The regular earthquake activity in Bárðarbunga volcano continues, it follows the same pattern has it has been doing for the last 7 – 8 months.

The largest earthquake had the magnitude of 3,2. Other earthquakes had smaller magnitude. This earthquake activity is like the earthquake activity before, there doesn’t seems to be a lot of difference between the earthquake swarms that are now taking place between weeks.

Öræfajökull volcano

There is a interesting earthquake activity taking place in Öræfajökull volcano. It suggest that some magma is entering the volcano at depth (5 – 10 km). At the moment there is nothing that suggests an eruption is getting close, however the eruption history of Öræfajökull volcano is not well known and no reliable data exists on what might happen in the case of eruption. At the moment, all of the earthquakes taking place are minor, suggesting the amount of magma entering Öræfajökull volcano is minor at the moment.

Langjökull (north)

Today (12-May-2016) an small earthquake swarm took place in north Langjökull volcano. This earthquake activity has been taking place in this area since the year 2000, it was started by the magnitude 6,5 earthquake in SISZ. The reason for this earthquake swarm are unclear. No change in the main volcano has been observed, both in terms of earthquake activity or other changes. One idea is that this are stress changes in faults at this area, suggesting they might be lateral faults, not connected to the volcano it self.

None of the earthquakes that took place had strong magnitude, largest earthquake had the magnitude of 2,0.


New – Analyzing articles

I plan on to start writing analyzing articles about volcanoes in Iceland in order to attempt to explain what is going on with the most active one and what might happen. Those articles will take few days to write, that means I won’t write many of them each week if needed. This is also going to cover history of the volcano if that is possible. I am going to try and expand this website a little in order to bring in more readers.

Hardware support needed

Since I have to go the dentist when I go back to Denmark (sight). I can’t afford the hardware upgrade and maintaining my desktop computer (I got a failing hard drive). I also need hardware for setting up a second geophone computer in Denmark and a new Power supply for my main earthquake computer, it now running a 350W power-supply from a different computer, making it a little under powered.

Here is the list of hardware needed if anyone can help me with this.

1 500W power supply for my main earthquake computer (It has to be Intel six CPU pin power compatible).
1 1TB hard drive for my main desktop computer. The current hard drive is failing, its making clicking sounds, suggesting that its read head is about to fail.
1 1TB hard drive for my main earthquake computer. This for my main backup of all my data (earthquake data and other important data, images and so on). The second backup is on the internet. I so far haven’t been able to setup my third backup plan.
1 500GB to 1TB hard drive for my second geophone computer in Denmark.

Extra

1 Used laptop that is faster than 2,3Ghz and with more than 2GB ram. It can be used, it just has to work and be younger then 2010 model of laptop. It doesn’t have to have Windows installed on it. It does have to have a working hard drive.

Thanks for the support. 🙂

Earthquake swarm ~125 km north of Kolbeinsey Island

Donations

Please remember to support my work with donations. My main job in this writing is to convert hard to read data about earthquakes or volcanoes into human readable format. It might not sound like a lot, but it can be a time consuming work to read all the data in their raw format (if I have to) and figure out (or try doing so) what is going on at times. Thanks for the support.

Kolbeinsey earthquake swarm

This earthquake swarm started sometimes yesterday (09-May-2016) or last night (10-May-2016), the first earthquakes appeared on SIL network at 01:03 UTC. This area north of Kolbeinsey Island is located around 125 km north of it. It is thought that this area had an eruption in the last few years (I can’t find the exact year), but it was not confirmed far as I know. Mostly due the location far from the coastline. It is difficult to know for sure what is exactly going on at this location. Activity has been going up in past few months in this area.

This area is rather unknown, but some study has been done into it. I’m sure on the details. There is a possibility that activity is going to continue in this area for next few days. If an eruption takes place, nobody is going to notice it due to distance from nearest population center (~200 km).

Please remember to support my work (writing on this website)

Send to Kindle

Please remember to support my work with donations or by buying from Amazon. My work takes often several hours during the day and my social income is low by any standard. The month of may is also going to be costly for me for many reasons. One of them is that I lost my grandfather on 30 April and I’m going to attend his funeral in few days time. I won’t say when the funeral is going to take place, since that was not my grandfather wish (I don’t know the proper English word for this type of funeral).

I am also going to be in money problems in general until I get a job in Denmark, but I’m going to start my job search on Monday. I do hope that it goes quickly so that I can start to have better income than I currently do.

Thanks for the support. 🙂

New website

I am going to start a new website once I have the money to buy the domain. It is not going to be about volcanoes, it is going to be about technology, computers, satellite dishes, antennas and everything that I have interest in.

Plans about creating a company

I also have plans about creating a company. It is few years away until that becomes reality (2 to 4 years). I have however started the basic plans that have to take place until I create the company legally in Denmark (or Germany).

Earthquake activity in Bárðarbunga volcano (Week 17)

Send to Kindle

After a short period of quiet, it seems that Bárðarbunga volcano has started again making earthquake swarms. The source of this activity is the same as before, inflation of Bárðarbunga volcano and infiltration of magma at shallow depth (that might not erupt).

Largest earthquake in this swarm had the magnitude of 3,4. Other earthquakes in this swarm had smaller magnitude. The number of earthquakes in this swarm was typical, around 20-ish. Currently the activity has stopped, but it is going to start again in few days, as has been the pattern since end of the eruption in February 2015.

Images of few of Iceland volcanoes

Send to Kindle

When I flew to Denmark on 14th of April the weather was mostly clear skies over Iceland. This allowed me to take pictures of few of the volcanoes in the flight path I was going. Due to constrains in WordPress I can’t show you the images here as I had hoped.

The images can be seen here. I’ll put up a special html page for them later on with text on what volcano you are seeing. Copyright of this images belongs to Jón Frímann Jónsson. They are free for personal use, but commercial use requires an license from me.

Little connection to the internet 15th – 29th of April, also broke

Send to Kindle

Since I’m moving back to Denmark I’m going to be without any internet connection in the days between 15th to 29th of April. I might have some limited internet connection during that time, but nothing that I can use to write articles or continue to monitor earthquakes activity.

Any activity in that period can be posted in comments to this article. I’ll try to make a new short article before the comments close automatically after 14 days.

Donations

Please remember to support my work (I’m broke). It is also expensive to move like this and I don’t know at the moment when I’m going to get a job in Denmark. It might take few weeks until I get a job. Thanks for the support. 🙂

As I have mentioned before at some point, this earthquake activity in Bárðarbunga volcano is now a weekly feature, or close to it. I’m expecting more earthquake activity in next few days, or at least until next magnitude 3,0 or larger earthquakes takes place in Bárðarbunga volcano.

Largest earthquake in this swarm had the magnitude of 3,2. The second largest earthquake in this swarm had the magnitude of 3,0. Other earthquakes where smaller in magnitude. This earthquake swarm is over for now.

My laptop

My laptop is now showing clear signs that its about end its usefulness and a complete hardware failure is imminent. I don’t expect to use it a lot after Friday. If it fails before that time I won’t be able to post updates for the next two days (until 14-April-2016).
