Magnitude 4,6 earthquake in Bárðarbunga volcano

At 00:08 UTC on 23-October-2018 a magnitude 4,6 earthquake took place in Bárðarbunga volcano. This is the strongest earthquake in Bárðarbunga volcano for at least three months. A second earthquake with a magnitude of 3,5 happened at 00:12 UTC. This earthquake activity had earlier smaller earthquakes happening in Bárðarbunga volcano. It started yesterday (22-October-2018) with few minor earthquakes.

Other earthquakes in this earthquake activity were smaller in magnitude. This type of earthquake activity in Bárðarbunga volcano is now common after the end of the eruption in 2015.

Update on 24-October-2018

Icelandic Met Office has revised the magnitude of few of the earthquakes that happened in Bárðarbunga volcano. Now the magnitudes of the largest earthquakes are magnitude 3,9, magnitude 4,6 and magnitude 3,5.

Earthquake activity in Öræfajökull and Bárðarbunga volcanoes

This is article is set-up in this way to save me some time due to the fact that I have to go to work tomorrow at 07:00 UTC (this is until 23rd October 2018).

Öræfajökull volcano

Since yesterday (01-October-2018) there has been a earthquake swarm in Öræfajökull volcano. There has been several dozen earthquakes in this earthquake swarm. Most of them are small. Largest earthquake in this swarm had a magnitude of 3,1 and was felt on nearby farms (there is no town or village close to Öræfajökull volcano). This earthquake swarm is currently ongoing.

Bárðarbunga volcano

A magnitude 3,0 and 3,6 earthquakes happened in Bárðarbunga volcano today. The smaller earthquake happened early in the morning but he larger one at 13:08 UTC. There hasn’t been any large amount of earthquake activity following this earthquakes. This is now the normal pattern of Bárðarbunga volcano since the eruption 2014 – 2015 (Holuhraun).

Magnitude 4,2 earthquake in Bárðarbunga volcano

Today (14-September-2018) at 10:40 UTC an magnitude 4,2 earthquake took place in Bárðarbunga volcano. Second largest earthquake in this swarm had a magnitude of 2,9. Other earthquakes that happened were smaller in magnitude.

This earthquake activity is normal for Bárðarbunga volcano as it continues to inflate after the eruption 2014 – 2015. At the moment the rate of this magnitude earthquake seems to be around 1 earthquake each month. It seems that rate of earthquakes is continuing to drop and soon it is going to be one to two earthquakes a year like this in Bárðarbunga volcano.

Earthquake in Bárðarbunga volcano

Today (16-August-2018) a magnitude 3,5 earthquake took place in Bárðarbunga volcano. At the moment this is just a single earthquake with no aftershocks.

It is possible that this is all the earthquake activity that is going to happen in Bárðarbunga volcano for the next few hours to days.

Minor earthquake swarm in Bárðarbunga volcano

Today (1-August-2018) at 07:08 UTC an earthquake with magnitude 3,7 happened in Bárðarbunga volcano. Second largest earthquake had a magnitude 2,9. Other earthquakes are smaller in magnitude.

The source of this earthquake activity is magma. In the news today it is reported that hydrothermal activity remains high in Bárðarbunga volcano caldera rim and steam can be observed in the areas were the glacier has been melted through.

Donations

Due to few payments (I am currently finishing paying off everything in Denmark) I need donations for August (because I am working I was able to pay everything, but it didn’t leave me with a lot to buy food in August). It helps me run this website, keep my self fed and keep everything going for me in the month of august. If you can’t donate due to your own circumstances don’t worry about it. Thanks for the support. 🙂

Earthquake activity in Bárðarbunga volcano

Today (20-July-2018) at 06:28 UTC a magnitude 3,4 earthquake was in Bárðarbunga volcano south-east part of the caldera. It was followed by several smaller earthquakes during the day. Earthquake activity is common in Bárðarbunga volcano at the moment, but rate of earthquakes happening continues to drop every 3 – 6 months. When earthquakes happen they are often larger in magnitude.

There is a risk of larger earthquake in next few hours to 48 hours. If nothing happens after 48 hours there is unlikely going to be a another larger earthquake happening. The magnitude that can be expected is above 4,0.

Deep earthquake swarm south-east of Bárðarbunga volcano

Since yesterday (18-July-2018) there has been a deep earthquake swarm south-east of Bárðarbunga volcano. Earthquake swarm in this location are common and due to their depth are always the result of magma injection into the crust in this area.

Most depth recorded in this earthquake swarm was 26,3 km and the shallowest was at 13,4 km depth. Error margin might be high in this location due to distance from SIL stations. Smaller earthquakes (magnitude 0,0 – 1,0) are harder to locate and give correct depth. Activity at this location is sometimes followed by a large earthquake in Bárðarbunga volcano (main). That doesn’t always happen. It is not possible to know if that is going to happen now.

Strong earthquake swarm in Bárðarbunga volcano

Today (14-June-2018) a large earthquake swarm happened in Bárðarbunga volcano.

Largest earthquake had a magnitude of 4,9 (at 15:05 UTC) and this is the strongest earthquake since January. Other magnitudes where 4,1 (at 13:04 UTC), magnitude 3,3 (at 13:25 UTC), magnitude 3,1 (at 13:36 UTC), magnitude 3,5 (at 16:35 UTC). Other earthquakes were smaller in magnitude.

This earthquake swarm is the strongest since January-2019 (article here). The difference is that this earthquake swarm seems to be larger then the one in January. This earthquake activity is the result of a inflation happening in Bárðarbunga volcano. There was no harmonic tremor following this earthquake activity. I don’t know how much Bárðarbunga volcano has inflated since end of the eruption in February-2015. This type of earthquake activity (swarm with large earthquakes) should be expected few times a year for next few years.

Thank you note

I’ve been having a bad time in last few days. What I did think as a solution turned into a major problem. The result of this is that I am going to move back to Denmark soon as November (it might get delayed until mid-January to February) if I have all the money issues in order and enough to pay for transport of my belongings back to Denmark (that is expensive, but I am going to sell some stuff now to lessen the amount along with stuff I’ve never transported to Denmark). This instability spilled a bit into this website, Facebook and twitter (both sites). I’ve removed the articles in question with comments and everything since I felt it was not right to keep the articles online.

I want to thank people that supported me with good and positive comments in the last few days. I decided do refund few donations that I got during this. I felt it unfair to keep them after the situation did calm down.

Work hours

I am working now 08:00 – 16:00 until September. From September until mid to end of October I am going to be working 07:00 – 18:00 (some days longer).

Two strong earthquakes in Bárðarbunga volcano

Today (17-May-2018) at 15:56 UTC an earthquake with magnitude 3,7 took place in Bárðarbunga volcano. Few minutes a larger earthquake happened at 16:00 UTC and had a magnitude of 4,0. A earthquake with magnitude 1,9 happened at 16:01 UTC. No other earthquake has happened since then.

The location of this earthquake swarm was at the normal location that has been seeing earthquake activity in last few months. Currently there is a bad weather in this part of Iceland but nothing is suggesting that an eruption is going to happen in Bárðarbunga volcano following this earthquake activity. The reason for this earthquake activity is inflation of Bárðarbunga volcano.

Strong earthquake activity in Bárðarbunga volcano

Today at 16:13 UTC (29-April-2018) a magnitude 3,9 earthquake took place in Bárðarbunga volcano. Earlier earthquake had a magnitude at 2,8 and took place at 05:01 UTC. This was also the second largest earthquake that happened today.

This earthquake activity is normal for Bárðarbunga volcano at the moment. This earthquake activity happens since Bárðarbunga volcano is inflating after the eruption in 2014-August to 2015-February. Current rate of this type of earthquake activity is a magnitude 3,0 or larger earthquake every 2 to 4 months. This used to happen weekly in 2015 and 2016. Earthquakes are now fewer but magnitude is often larger.
