UK government failed preparing for a volcano ash threat from Iceland

According to a news article in The Independent today. It appears that UK government was unprepared for a volcano eruption in Iceland that could send ash cloud in the direction of UK. Like that did happen in Eyjafjallajökull volcano eruption in the year 2010. But according to the same news the UK government dedicated to drop such plans from there risk assessments and planning in the year 2009. A whole year before the eruption in Eyjafjallajökull volcano took place.

This was most likely also the case in other countries in Europe where the ash cloud did come as a surprise to governments across Europe and they did appear to be unprepared for it when it halted all flights in Europe for almost a week.

Earthquake activity continues in Krýsuvík volcano [updated]

Early morning today (2. March 2011) there was a spike of earthquakes in Krýsuvík volcano. This earthquake swarm took place west of Kleifarvatn lake as the main center of the activity has been for the past two years. This type of activity can be expected in Krýsuvík volcano in the coming weeks in my opinion. Both long earthquake swarms and short ones, like the one that did happen early morning today.

The Icelandic Met Office has released a picture showing the earthquake activity in Krýsuvík volcano from the year 2004. Along with accumulated strain from those earthquakes and other useful data.

I am expecting more earthquake activity in Krýsvík volcano area. But at the moment it is a bit hard to know for sure if this is going to result in a volcano eruption. But in my opinion that is going to be the result in the end. But currently it is all a question about when, rather then if in my opinion.

Update: There was a earthquake with the size ML3.6 at 17:56 UTC according to the automatic data from Icelandic Met Office. This earthquake was a more south the earthquakes that happened last weekend. This can clearly been seen on the map data that Icelandic Met Office has released (see above). The depth of this earthquake was 3.6 km.

Press disclaimer: I am not a geologist and my opinion is not the one of a expert in this matter.

Earthquake activity continues in Krýsuvík volcano, but at slower rate

At the current time earthquake activity in Krýsuvík volcano has slowed (when this is written) considerable down. But the earthquake activity has not stopped, even if it has slowed down considerable down. What is also interesting are the news about increased hydrothermal activity in Iceland (see older blog post for information on that). This lack of quiet time is interesting and gives the clues into that direction that inflow of magma might be constant. But might have slowed down as the earthquake swarm did slow down. It is interesting to notice that slowdown and few earthquakes where also common in the weeks before the eruption in Eyjafjallajökull volcano.

This activity in Krýsuvík volcano has gone out in the Icelandic media fast. But there have been the common questions if this area is about have a eruption. But at current time the general agreement is that nobody is sure about it.

Off-topic! I want to thank all the people how have supported me with donations. But I did not expect this huge response that I got. Thanks so much for the support. It won’t be forgotten in the future.

Having income problems, asking for donations with reluctance

As many of you know I have been running for a donations to buy a computer LCD screen. That did work out and I want to thank you all for that. But I want to use the money that was donated for what they are intended. So the donations for a new PC monitor go into that and into buying a table.

But this month after all the bills are paid I am left with nothing to buy food with. I got some money on my VISA card. But that is a bad path to go into. I already know that by experience.

As I find it honest to people how donate money to me. My income is as follows. This is converted from ISK to USD, EUR and DKK. This numbers are also public at tr.is web site, as I am on social benefits (fixed income).

All numbers are approximate and subject to exchange rate of ISK.
ISK: 139.000
USD: 1.197,45
DKK: 6.445,63
EUR: 864,64

I can provide a screen-shot of my bank-account numbers if asked for. Just email me if you require that. But as I sad. This numbers are public as this is the social welfare in Iceland.

In the absolute worst case I move back to Iceland for a few short years while the worst of the economic recession is over in Iceland and then I move to Germany. I will see how this develops over the course of March, April and May (maybe). I have a plan D and E that I am describing above.

I thank you for all your support. Both the one that has been given and the one that has yet to be given.

Hydrothermal areas grow larger in Krýsuvík volcano due to earthquake swarm

According to news from Rúv. It appears that hydrothermal areas in Krýsuvík volcano are growing larger following the earthquake swarm in the past few days. This same news also tells that the number of cracks in the ground have grown in numbers following the earthquake swarm, this allows more water to get into contact with the hot rock and that warms the water up fast.

Currently the earthquake swarm in Krýsuvík volcano is quieting down. But that might chance without any warning at all. But won’t be surprised if the earthquake swarm stops completely.

In my personal opinion this is a clue that magma might be pushing it’s way up the Krýsuvík volcano system. I get the clue from the increased hydrothermal activity in the this area. But at the moment it is too early to know for sure if this is going to result in a eruption or not. But if this activity continues as it has then a eruption is going to happen one day. That can also chance without any warning at all. But this type activity means that status of the volcano it self is constantly changing and makes it unpredictable. How eruptions in Krýsuvík volcano behave is also a big unknown.

Update: According to Rúv evening news (Icelandic, video) there appears to be magma related aspect to this weekend earthquake swarm in Krýsuvík volcano. According to Dr. Páll Einarsson geologist at Iceland University it appears that magma is the source (as stated above) of this weekend earthquake swarm. This news also says that there has been a lot of earthquake activity in Krýsuvík volcano over the past two years and this earthquake activity is not only tectonic as is common in this area. The news at Rúv also says that geologist in Iceland are wondering and unsure what exactly is going on at Krýsuvík volcano at the moment. But the reported inflation in the news at Rúv is sad to be 10 cm (I do not know if that number is accurate or not). But it clearly a reason now to watch the activity at Krýsuvík volcano. If there is a eruption in Krýsuvík volcano it is going to be a harmless (as it can be) lava eruption. Unless it is under water, but then there is a Surtsey type of eruption for as long there is water getting into the crater. So don’t expect aircraft problem if there is a eruption in Krýsuvík volcano.

Overview of the earthquake activity in Krýsuvík volcano

Today has been interesting in regards to the earthquake activity in Krýsuvík volcano. But today there have been well over 800 earthquakes (far as I can tell). Over the past few hours the earthquake activity has slowed down a little bit. But far as I can tell it is far from over and might start to pick up again at any time and with no warning at all.

Icelandic Met Office released a picture of the earthquake activity in Krýsuvík volcano so far for the year 2011.

Large earthquake swarm in Krísuvík volcano

After four days of continues earthquake activity it appears that Krísuvík volcano has stepped up it’s activity by a order of magnitude. Since midnight there have been over 400 earthquakes in Krísuvík volcano. The activity is continuing when this is written and does not show any signs of slowing down at this moment. Geologist in Iceland are expecting more earthquakes in this area over the next hours and even earthquakes that are larger then ML3.0 in size.

The largest earthquakes where ML3.3 and ML3.7 in size. This is automatic size by the SIL system. The depth of the earthquakes was 4.7 km and 1.1 km according to the automatic SIL system. Due to high number of earthquakes the SIL system is putting earthquakes down all around the Reykjanes Peninsula. While there might be some earthquakes there, the number is not nearly as high as can be seen on the map. The earthquakes can be located by there low quality number.

Given the location and how this earthquake swarm is behaving it is my opinion that this is due to a magma is pushing up the crust in this area. But it remains a question of this is going to start a eruption or not. But the chances are growing for as long as this earthquake pattern holds up in Krísuvík volcano. If a eruption starts in Krísuvík volcano it is going to one of Hawaii type eruption, unless it is under water then it is going to be explosive for as long there is water getting into the crater. Last time there was a eruption in this area a 25 km long eruption fissure did form.

For now however all that can be done is to wait and see what happens. This earthquake swarm is going to continue for the next few hours and even days. The largest earthquakes can be seen on my geophone sensors here.

Two day long earthquake swarm in Krísuvík volcano

While this earthquake swarm in Krísuvík volcano does not appear to be big in size. It is clear that was rather long and might even be ongoing. But it is interesting how long this earthquake swarm did last. So far the time is about 2 days. It is impossible to know if the earthquake swarm is over or not. Current number of earthquakes is about 60 earthquakes so far.


Picture is from Icelandic Met Office graphic web tool.

The earthquakes are on North-South fault line according to the visual evidence. Depth of the earthquakes is from 12 km and up to 3 km at the moment. It is hard to know at the moment if this is due to magma inflow under Krísuvík volcano or just normal tectonic activity along the rift zone in Reykjanes.

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.
