A ML2.3 earthquake in Grímsfjall volcano

A earthquake with the size of ML3.3 ML2.3 took place at 01:19 UTC in Grímsfjall volcano. At the current moment no other earthquakes have been spotted following this single event. It is also remains unclear at the moment if this is a start of a eruption in Grímsfjall volcano. But at the moment there is nothing that indicates that a eruption is about to start in Grímsfjall volcano. But that can change with out any warning at all.

Note that EMSC is reporting this earthquake with the size of ML4.3. It is unclear at the moment what is the correct size for this earthquake.

Text updated at 11:40 CET on the 25th of February 2011. EMSC did change it down to ML3.3 size.

Human made earthquakes in Hengill volcano

It appears that operations of Orkuveita Reykjavíkur are creating the earthquake swarms that have been seen in Hengill volcanoo. But as part of operations in Hengill geothermal plant they pump down cold water into the bed rock under considerable pressure. This is according to Sigþrúður Ármannsdóttir a geologist at Icelandic Met Office. But Vísir.is quoted here on this earthquakes swarms in Hengill volcano.

This type of earthquake swarms are going to repeat them self for as long Orkuveita Reykjavíkur is pumping down cold water into the bed rock in Hengill volcano. As the water creates a pressure change in the surrounding rock.

The most intresting earthquakes that happened as because of this swarm where 3.8 km NE of Hveragerði. But the size of that earthquake was ML2.6 (automatic size). and it was considerable distance from Hengill volcano and appears to have been triggered by the earthquake swarm in Hengill volcano (unclear however and just my own observation).

News about this.

Small earthquake swarm in Krísuvík volcano

Currently there is a small earthquake swarm in Krísuvík volcano. This earthquake swarm is small and is only about 20 or so earthquakes at current time. It is impossible to know if this earthquake swarm is going to continue or grow at present time. But it is not uncommon in this area for a small earthquake swam to be a warm up for a larger one. But as always there is just a wait and see what happens in the area.

The largest earthquakes in this earthquake swarm have reached up to ML2.0 in size so far.

Earthquake swarm at Upptyppingar

I notice that there is a small, yet growing earthquake swarm taking place close to a small mountain named Upptyppingar. This mountain is within the fissure swarm of Kverkfjöll volcano but the area is in it self not active volcanically.

Few years ago (2007) there was a earthquake swarm in this area that did have something about 2000 earthquakes over a 48 hour period. The reason why there is earthquake activity in this area is due to magma being pushed up into the bedrock below. This process is something of the same that took place before the Eyjafjallajökull volcano eruption. But with the major difference that here is no central volcano doing this.

Earthquake pictures from IMO from that time. No map sadly as I forgot to save them or they are stuck on my main computer that holds all my geological data.

New earthquake swarm in Hengill volcano

A new earthquake swarm has started in Hengill volcano. This earthquake swarm is in the same location as a earthquake swarm that took place there few weeks ago (see here).

So far this earthquake swarm has mostly been made out of small earthquakes. But all earthquakes are below ML2.0 in size so far.

It is unclear why this earthquake swarm is taking place. But the reason might be that the geothermal power plant that is in the area is pumping down or up ground water.

Continued quiet time in earthquakes and volcanoes

It seems that the quiet time continues in Iceland. Besides small earthquakes swarms in Pesthnjúkar volcano and small earthquake swarm in Hengill volcano, there was also a earthquake swarm in Bárðarbunga volcano that did get into the world press. Other then this it has been quiet and no volcanoes have been showing signs of starting a eruption soon.

It is all quiet in Iceland, so not a lot of activity updates coming from me at the moment. But I hope to write soon a information post about one of Iceland volcanoes or earthquakes zones to pass the time.

Fundraiser for items and trying to be a professional blogger





Euro foreign exchange reference rates (ecb.int)

While I am thankful for the all the readers that I get on this site it does not change the fact that I need to earn a good living. Currently I am on a fixed income (Welfare) due to my Asperger’s syndrome, but I have a really mild version of this syndrome. This fixed income is not a lot and never has been. But due to my move to Denmark is going to get even less. In Iceland I got 159000 ISK (about 997€, the exchange rate euro/ISK is poor at the moment) but when I moved to Denmark it is going to get lower and in the line of something about 138000 ISK (about 865€). So I don’t have a lot of money to work with over the month.

While this blog originally started as a minor blog about earthquakes and volcanoes in Iceland it grew fast. From September 2010 and until today this blog has had 424,518 page views. My helicorder web pages have had 2,090,461 page views since I did set those pages up (the year 2006). Based on this fact I did decide to try being a professional blogger. That includes getting enough money to live from this blog. I do not know how long that is going to take. But given how long it took University today (started as a blog) to get into that status I might have to wait few more years until I get enough income from this blog to get a stable living from writing on the blog site about Icelandic volcanoes and earthquakes.

This leads me to the ever ending results that come from this type of situation. I need to get a job. That evidently is going to give me less time to attend to this blog. I also plan going to school here in Denmark to learn programming, languages and electronics (if I can learn electronics). So work with that is going to give me less time in the end to write here. But the school is few months off so I am just going to wait and see how that goes. As I sad in a comment yesterday there might be a delay until updates return to normal because I lack the tables to setup my computers properly. There also might be a delay until everything gets back to normal updates, as it might take a good time to get connected a ADSL2+ service. I do not know when I get ADSL2+ connection, as I do not know the service time here in Denmark. Currently I am on poor 3G connection for the internet.

I am a writer and my plan is to write and publish eBooks to sell on Amazon. I am also thinking about releasing them in a blog format (I am still considering that option). I hope to get a income from that in the future. But there is going to be a while until I can start selling eBooks on Amazon and get a income from that sale.

Due to how low income I have. I have decided to do a little fundraiser here. For two tables that I need and a new (or used) PC monitor. I am going to do this as cheap as possible.

Computer Table price is 400 DKK (they did rise the price, damit!) – This is just a normal table. I do not like computer special boards.
TV table price is 300 DKK.
23″ LCD PC monitor price is 999 DKK last time I did check. There might be cheaper 23″ LCD PC monitors for sale in Germany. But I do not know the price on them. I might also buy a used PC monitor to use for a short time while I try to get the money for a new PC monitor. This are the prices where I live locally. But I want to buy this locally so I can get this items right away.

All other support besides this is also welcomed. I must point out that I can only transfer funds that go into my PayPal account into my credit card at the moment (I do not know if that changes when I setup a new PayPal account for Denmark). So any usage that I have there is going to minus first from whatever I transfer into that card. PayPal also takes 5% of whatever I transfer into my credit Card.

Here is the PayPal donate button. This the first time that I do this type of button. So please let me know if there are any issues with it.

Thanks for the support! This blog is going to remain free as always. That is not going to change.

Earthquake swarm in Presthnjúkar volcano (Langjökull glacier)

A earthquake swarm of 70 something earthquakes have been taking place close to Presthnjúkar volcano in Iceland. This activity is tectonic in nature and is because of the rift zone. This volcano is located close to south end of Langjökull glacier, but Langjökull glacier covers two volcanoes (north Hveravellir and south Presthnjúkar). One at the north end and a other at the south end. This volcano last erupted in the year 3500 BC (?) according to GVP.

Earthquake swarms are common in this area and happen regularly. But last large earthquake swarm in this area was in June 2009. The largest earthquake that did happen today was felt in nearby area according to Icelandic news.

Eartquake swarm in Hengill volcano

The Icelandic volcano known as Hengill did have a minor earthquake swarm of 20 something earthquakes today. This earthquake swarm might be related to geothermal power plant activity nearby (by pumping down or up water in the area). But at the moment I do not have it confirmed and this has also not been confirmed by the news.

This earthquake swarm in this area is normal and this volcano has several every year as it located on the main rift zone in Iceland. The last large earthquake swarm in this volcano took place during the year 1997 to 2000. Then many earthquake up to size Mb5.0 took place in Hengill volcano.
