Magnitude 3,0 earthquake in Öræfajökull volcano

Today (24-March-2018) at 16:32 UTC a magnitude 3,0 earthquake happened in Öræfajökull volcano. There has been a lot of smaller earthquake activity in Öræfajökull volcano in recent days and the earthquake activity has been continuous for most of that time.

I am unclear at the moment if there is any change happening at this moment. There has been slight increase in earthquakes that have magnitude larger than 1,5 in recent days. Overall there has been no major increase in earthquake activity so far in Öræfajökull volcano. But it has been mostly continuous for last several weeks and that might be a sign of trouble in near future.

The magnitude 3,0 earthquake was felt in Öræfasveit and other nearby areas.

I’ll update this article later if anything major happens.

Quiet period in Iceland at the moment

At the moment there isn’t much happening. This is one of the quiet period that regularly happen in Iceland. How long this break is going to last is impossible to know. It might be few more days and maybe several more weeks.

Currently the only notable activity happening is in Öræfajökull volcano but this is the same type of activity that has been happening for weeks now and do not require a new article.

Ongoing earthquake activity in Öræfajökull volcano, fresh earthquake activity in Tungnafellsjökull volcano

At the moment the earthquake activity that started in Öræfajökull volcano on 25-February-2018 is currently ongoing. Most of the earthquakes happening are small, most are smaller than magnitude 1,0.

Tungnafellsjökull volcano

Directly north-west of Öræfajökull volcano is a another volcano making earthquakes. That volcano is named Tungnafellsjökull volcano. Most of its earthquake activity is also small earthquakes with magnitude smaller than 1,0. After the eruption in Bárðarbunga volcano 2014 – 2015 earthquake activity increased in Tungnafellsjökull volcano. Earthquake activity was also high during the eruption in Bárðarbunga volcano due to stress changes in the crust. It is likely that current earthquake activity is due to adjustment of tectonic stresses.

Fresh earthquake activity in Öræfajökull volcano

Yesterday (24-February-2018) and today (25-February-2018) earthquake activity increased in Öræfajökull volcano after a long quiet time. Largest earthquake recorded had a magnitude of 2,2. Other magnitude where from 0,6 and up to 1,2. All earthquakes are marked as at shallow depth, but that might not be correct.

This earthquake activity in Öræfajökull volcano is due to magma pushing up into the volcano. This is above background level of activity in Öræfajökull volcano since background level activity is around 1 – 2 earthquake a year (up to 10 earthquakes a year).

Earthquake activity in Öræfajökull volcano

Today (09-Februar-2018) at 05:07 UTC a magnitude 3,6 earthquake took place in Öræfajökull volcano. This is now the strongest earthquake in Öræfajökull volcano since this earthquake activity started in 2017. With earlier earthquake only having the magnitude of 3,4 (article here) on 3-October-2017. This increase in magnitude is something to worry about.

Only one earthquake has happened after this earthquake so far and that only had the magnitude of 1,7. I am expecting more earthquake activity in next few hours and days.

Earthquake activity in Öræfajökull and Esjufjöll volcanoes

I am writing about both Öræfajökull and Esjufjöll volcanoes in this article.

Öræfajökull volcano

Earthquake activity continues in Öræfajökull volcano. As before most earthquakes are smaller than magnitude 1,0. Earthquake activity is mostly in the caldera but reaches a little outside of it at times. Míla webcamera for Öræfajökull volcano can be found here.

Esjufjöll volcano

After a long time with no earthquake activity. Earthquake activity suddenly appeared in Esjufjöll volcano. As with Öræfajökull volcano, earthquakes do not happen in Esjufjöll volcano unless it is connected to magma movements. I don’t know anything useful about Esjufjöll since no eruptions are documented in the last 12.000 years. There might have been a small eruption in the year 1927 that lasted for 4 days, but I don’t have any useful information about that eruption if it happened. If an eruption does happen in Esjufjöll a glacier flood would go down to Jökulsárlón (this webcamera here).

Donations

Please remember to support my work with donations. Current lack of money is making me a bit stressful due to the electric bill and that I currently lack the money to pay it. I only need 925 DKK (124€). I had to buy some food in last few days that explains the increase from 94€ earlier. Thanks for the support. 🙂

The regular donation button has been moved to my PayPal account in Iceland from PayPal in Denmark. I post updates on this on the donation site (link in the banner). The main PayPal donation button is going to changed to Iceland in June. After that it is going to stay like that since I don’t have any plans on moving away from Iceland after I move back to Iceland in July.

Earthquake activity in Öræfajökull volcano

Earthquake activity continues in Öræfajökull volcano and it remains at yellow status [website can be found here]. Like before the earthquake activity is small in magnitude.

There is now a pattern to this earthquake activity. Just and while it happens there are changes in the tremor plot on SIL stations around Öræfajökull volcano. It is possible that this is earthquake activity showing it self on the SIL stations. Other explanations are also possible.

I don’t know for sure at the moment why this happens or why it shows up as it currently does.

Bad weather is currently blocking detection of small earthquakes in Iceland. A storm is going to pass over Iceland today and a second storm is going to pass over Iceland on Sunday.

Donations

Please remember to support my work since February-2018 is going to be really broke for me. Currently I don’t have enough money to pay the electric bills and I am missing close to 700 DKK (94€) so that I can pay it and then there is the whole month left for other things. In this case I need to buy food. Thanks for the support. 🙂

Moving to Iceland

I have managed to move up my plan on moving to Iceland. I can move in July rather than October. It saves me a bit on the tax payments in Denmark as soon as I move to Iceland my tax obligations in Denmark stop (from the day the move of legal home takes place). This is just a case of me not being able to afford on living in Denmark and there is nothing I can do about it. Since people with minor disabilities from a other country don’t get a job in Denmark (I am also uneducated and that doesn’t help).

Magnitude 3,1 earthquake in Öræfajökull volcano

A magnitude 3,1 earthquake took place on 18-January-2018 at 02:14 UTC in Öræfajökull volcano. This earthquake was followed by one magnitude 2,0 earthquake and one magnitude 1,8 earthquake. All other earthquakes where smaller in magnitude.

This earthquake activity was followed by an increase in higher frequency noise on the tremor plots around Öræfajökull volcano. This possibly was the swarm of small earthquakes detected in Öræfajökull volcano at the same time. I am not sure at this moment, but I do hope it gets clearer what is happening as more data is collected with increasing activity.

No changes in Öræfajökull volcano earthquake activity

Earthquake activity continues in Öræfajökull volcano as has been doing for past several months. Earthquake activity goes up and down a little, some days there are fewer earthquakes while in others there is more activity.

Current earthquake activity is consistent with volcano of this type (stratovolcano with rhyolitic type of magma). Earthquake activity happens when the magma or gas connected to it moves inside the volcano. That movement changes during the day and is never constant and impossible to predict.

Earthquake activity increasing again in Öræfajökull volcano

After quiet two weeks in Öræfajökull volcano earthquake activity has started in increase again. As before the magnitude of earthquakes happening remains small with only few earthquakes reaching magnitudes above 1,5.


Earthquake activity in Öræfajökull volcano. Copyright of this image belongs to Icelandic Met Office.

Largest earthquakes today (23-December-2017) had magnitude of 1,4 and 1,1. All other earthquakes that happened where smaller in magnitude. It is at the moment difficult to know if this current trend continues and earthquake activity continues to increase in Öræfajökull volcano or is going to start dropping off again. Based on earlier pattern in October and November the earthquake activity is going to continue to increase, reach a peak and then start to drop off again. The fact remains is that nothing is certain when it comes to volcanoes and it is close to impossible to predict and know what is going on in Öræfajökull volcano.
