Earthquake activity continues in Öræfajökull volcano

Earthquake activity continues in Öræfajökull volcano as before. Earthquake swarm happen now every few days and most of them are minor in terms of magnitude and number of earthquakes that happen. Today (15-Ocotober-2018) the largest earthquake that happened in Öræfajökull volcano had a magnitude of 2,1 and 1,5. Other earthquakes are smaller in magnitude.

This earthquake activity is due to magma flowing into Öræfajökull volcano at depth. What that depth is unclear at the moment. This earthquake activity happens in pluses with quiet period between them.

Update on the donation for new hardware

Thanks to donations last week I almost have all the money to buy a Raspberry Shake seismometer. I am still missing around ~268€ in order to buy the Raspberry Shake station. With this new hardware I am going to be able to provide a lot better data from what I currently have. This includes I hope a spectrograph of an earthquake (I need a linux computer for this. I’ll set one up once I’ve moved to Spain). I can’t do that with my current old hardware and software. For those that have donated already. Thanks so much for the support. 🙂

Earthquake swarm on Reykjanes peninsula

Today (3-Ocotber-2018) there has been a earthquake swarm on Reykjanes peninsula. Most earthquakes have been small and not found, but the largest earthquake in this earthquake swarm had a magnitude of 3,2.

The largest earthquake was felt in the blue lagoon. It seems that this earthquake swarm has stopped for now.

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).

Minor earthquake swarms in Öræfajökull volcano

An earthquake swarm started in Öræfajökull volcano yesterday (26-September-2018). Largest earthquake in this swarm had a magnitude of 1,2. Other earthquakes had a magnitude of 0,0 and up to 0,5.

This earthquake activity is because of magma is moving inside Öræfajökull volcano. This movement is mostly slow and often stops at times. This is going to continue for a long while longer in current phase. There is no risk of eruption in Öræfajökull volcano at the moment.

Donations

Please remember to support my work with donations. At the moment I am trying to save up for Raspberry Shake sensor to replace my current hardware that Böðvarshólar geophone station. The computer I used has already failed and I am currently using temporarily set-up (it often fails). I’ve gotten some donations but not enough to buy the Raspberry Shake sensor I need. Please see pinned article for more details. Thanks for the support. 🙂

Social Media

I have made the decision to open up my social media a little more. This is only the social media that I use to post pictures to. I can be followed on Twitter using the twitter buttons on the side on this website. If you only want geology information please use Iceland geology twitter. I retweet a lot of stuff on my regular twitter.

Magnitude 3,0 earthquake in Öræfajökull volcano

This evening (21-September-2018) at 21:15 UTC a magnitude 3,0 earthquake happened in Öræfajökull volcano. This was followed by a swarm of earthquakes and largest earthquake after the magnitude 3,0 earthquake had a magnitude of 1,4 so far.

I expect the largest earthquake to have been felt in nearby farms that are close to Öræfajökull volcano (some are in it roots). In recent weeks the magnitude of earthquakes in Öræfajökull volcano has slowly been moving upwards. This change is not by much at the moment.

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 swarm on Reykjanes peninsula (Bláfjöll area) [updated]

Earthquake swarm started today (13-September-2018) in Bláfjöll area. This earthquake swarm continued today with only minor earthquakes. At 20:17 UTC an earthquake with magnitude 4,1 happened in Bláfjöll area. This earthquake was felt over a wide area.

This earthquake swarm appears to be ongoing. There is a possibility that more earthquakes with magnitude above 3,0 might happen in next few hours to days.

Update 14-September-2018

Icelandic Met Office has updated the earthquakes in this area. Two earthquakes happened yesterday. One with magnitude 4,1 and one with magnitude 4,2. There are only few seconds between the earthquakes.

Please remember to support my work with donations. I am also trying to get enough donations so I can buy new Raspberry shake seismometers since my current hardware is out of date and is now difficult to maintain. Thanks for the support. 🙂

Strong earthquake swarm 88 – 90 km north of Kolbeinsey Island yesterday (8-September-2018)

Yesterday (8-September-2018) there was a strong earthquake swarm 88 to 90 km north of Kolbeinsey Island. Due to distance from the SIL network it is impossible to know how large and strong this earthquake swarm actually was. Largest earthquake reported by Icelandic Met Office had a magnitude of 3,3. Total of ten earthquakes with magnitude 3,0 or larger happened during this earthquake swarm.

Total around 30 earthquakes were detected but it can be assumed that total number of earthquakes might have been higher. At the distance from the SIL network smaller earthquakes are not detected. It is not possible to know for sure what is happening at this location due to distance from the coast and the SIL network.

Fresh minor earthquake swarm in Öræfajökull volcano

Yesterday (23-August-2018) an fresh earthquake swarm started in Öræfajökull volcano. This earthquake swarm seems to be progressing in the same way as earlier earthquake swarms. Earthquake activity in Öræfajökull volcano only happens when magma is on the move inside the volcano.

Largest earthquake in this swarm had a magnitude of 2,2 and the second largest earthquake had a magnitude of 1,9. Other earthquake activity has been as before and is mostly made of earthquake with magnitude 0,0 and up to magnitude 1,0. The magma in Öræfajökull volcano is slow moving and that is reflected in current earthquake activity.

This earthquake swarm seems to be ongoing at the moment. It is possible that more earthquakes that might be felt are going to happen. The largest earthquakes in this swarm were felt in nearby tourist areas.
