Magnitude Mw3,1 earthquake in Hamarinn volcano

Today (13-October-2019) at 17:44 UTC a magnitude Mw3,1 earthquake took place in Hamarinn volcano (no Global Volcanism Page, see Bárðarbunga volcano). There has been some earthquake activity in this area for last several weeks.

Last time there was this increase in earthquake activity in Hamarinn volcano an eruption happened in July 2011 without warning and no earthquake activity before it. That eruption remains unconfirmed by the professionals but I hold that we it did happened based on documented data (harmonic tremor, glacier flood).

Donations

Currently I only need 37259 ISK (263€/$292USD) to pay for the shipping of my belongings to Denmark. If all the amount is paid in time there won’t be any storage charge or at most a really small one (next week). I have to pay the storage charge before I get my belongings delivered. I unfortunately have to use tiny amount of this for transport and food. I plan on having that as minimal as possible. Thanks for the support. 🙂

Minor earthquake activity in Tungnafellsjökull volcano

Today (13-October-2019) a minor earthquake swarm took place in Tungnafellsjökull volcano. After the eruption in Bárðarbunga volcano there has been a ongoing earthquake activity in Tungnafellsjökull volcano, why that it is remains unexplained. There are suggestion in recorded data that magma is moving inside the volcano at slow rate but that remains unclear for now.

Tungnafellsjökull volcano has no known eruption history in last 12000 years so its impossible to know what signs if any appears before an eruption happens. Currently there are no clear signs that Tungnafellsjökull volcano is preparing for an eruption. This might just be after-effect of the eruption in Bárðarbunga volcano that placed a lot of crustal strain on Tungafellsjökull volcano and resulted in a lot of earthquake activity in that volcano during the early start of that eruption in Bárðarbunga volcano.

Donations

Currently there is only need for about 37.259 ISK (263€/$292USD) until I have all the money needed for paying for moving of my belongings and to get them delivered to me on time without having to pay a lot of storage charges (if any). Unfortunately I have to use tiny amount of this money to pay for transport and little food costs in Iceland and Denmark. I am going to keep that amount to absolute minimal amount. Thanks for the support. 🙂

There has been minor earthquake activity in other parts of Bárðarbunga volcano. I don’t know if that activity is connected to the stronger earthquake activity.

This earthquake activity looks like normal earthquake activity in Bárðarbunga volcano since the end of the eruption in February 2015. No other earthquake activity has happened after this earthquake at the writing of this article.

Magnitude Mw4,2 earthquake in Bárðarbunga volcano

Today (8-September-2019) at 02:00 UTC earthquake swarm started in Bárðarbunga volcano. From 02:00 to 02:03 UTC total of five earthquake took place in Bárðarbunga volcano. Largest of them had a magnitude of Mw4,2 and second largest had a magnitude of Mw3,2. Other earthquakes that took place had a smaller magnitude.

Earthquake activity like this in Bárðarbunga volcano is common. This type of earthquake activity happens once every month after the end of the eruption in Holuhraun (2015).

Earthquake swarm in Bárðarbunga volcano

This earthquake was in the north-east part of the caldera. In last few months earthquake activity has been increasing in that part of the caldera. Earthquake activity in Bárðarbunga volcano is due to magma inflating the volcano.

Increase in earthquake activity in Hamarinn volcano (Bárðarbunga volcano)

Over the last few days there has been increase in earthquake activity in Hamarinn volcano (Bárðarbunga volcano). In Global Volcanism Program record this area is known as Loki-Fögrufjöll. Largest earthquakes today (12-August-2019) had a magnitude of 2,8 and 2,5 and other earthquakes have been smaller in magnitude.

Last time Hamarinn volcano had this type of earthquake activity it erupted for few months after it had started. That was on 12th July 2011. I wrote about those events here and here (glacier flood that followed, July 13th 2011). There were minor additional eruptions in August and November in 2011 according to the tremor data, those eruptions only lasted for ~4 hours at most. Since then this area has mostly been quiet and did drop down in activity after the eruption in Bárðarbunga volcano in 2014 to 2015.

It is unclear what is going on in Hamarinn volcano, for now there is no eruption taking place and any eruption is going to appear clearly on harmonic tremor data on the SIL network. It seems that eruptions in Hamarinn volcano start without any earthquake activity, I don’t know why that is. Last major eruption in Hamarinn volcano took place in the year 1910 from June 18 to October.

Earthquake in Torfajökull volcano

Today (20-Juli-2019) at 14:15 UTC an earthquake with the magnitude of 3,3 took place in Torfajökull volcano. This earthquake took place in south part of the caldera of Torfajökull volcano. This earthquake might have been felt by tourists in the area.

There has not been a lot of aftershocks following this earthquake for now. Last earthquake with magnitude above 3,0 took place on 12th of July and this means there might be a serious increase in earthquake activity in Torfajökull volcano. There are no obvious signs that Torfajökull volcano is about to erupt but it is also not known what is needed to make an eruption happen in Torfajökull volcano. Best action for now is to continue to monitor the activity in Torfajökull volcano.

Increase in earthquakes in Katla volcano

Since yesterday (13-July-2019) there has been a increase in earthquake activity in Katla volcano. There are no signs of anything more happening than just this increase of earthquakes.

This increase in activity is something to keep a watch for but this has happened before without resulting in a eruption in Katla volcano. There have been reports on high volume of water level in the cauldrons in Mýrdalsjökull glacier. I don’t know if that is connected to this increase in earthquake activity. There is an expatiation that water is going to break out soon and the flood is going to be the largest since 2011. That might increase earthquake activity in Katla volcano once that happens. For now however nothing has been reported in the news of such a event.

Magnitude 3,2 earthquake in Torfajökull volcano

Today (12-July-2019) at 17:16 UTC a magnitude 3,2 earthquake took place in Torfajökull volcano. This earthquake might have been felt by tourists in the area. This earthquake being felt has not yet been reported according to any news media.

This area of Torfajökull volcano has been having earthquake activity since January 27 when a magnitude 3,7 earthquake took place there. That activity was followed by a larger swarm of aftershocks than have so far happened. That might change without warning. This earthquake activity is interesting but I am not sure if it means anything, at least for now.
