Two strong earthquakes in Bárðarbunga volcano yesterday (14-July-2020)

This article is a bit late because I didn’t have the energy to write it yesterday (14-July-2020).

Two earthquakes with magnitude 3,0 (at 23:41 UTC on 13-Jyly-2020) and a magnitude Mw3,6 (at 00:56 UTC on 14-July-2020). This earthquakes are because Bárðarbunga volcano continue to inflate as it has been doing since the end of the eruption in Holuhraun in February 2015.

There were two aftershocks with magnitude of Mw2,5. Other earthquakes that happened were smaller in magnitude. This activity is normal now for Bárðarbunga volcano and no eruption is expected and would require a lot more earthquake activity as was seen during the 2014 August and September start of the eruption from Bárðarbunga volcano.

Today (14-June-2020) an earthquake with a magnitude of Mw3,4 took place in Bárðarbunga volcano. This is now the regular and usual earthquake activity in Bárðarbunga volcano and is connected to inflation in the volcano after the 2014 – 2015 eruption in Holuhraun.

This earthquake activity is located normally either in the south-east part of the caldera or in the north-east part of the caldera. This earthquake was located in the south-east part of the caldera. More earthquake activity is going to happen in Bárðarbunga volcano in next few months to years and should not be a surprise to anyone.

Magnitude Mw3,5 earthquake in Bárðarbunga volcano during the night (30-May-2020)

A single earthquake took place in Bárðarbunga volcano at 01:20 UTC. This earthquake had a magnitude of Mw3,5 and no other earthquakes took place following this earthquake. This type of earthquake has been followed by stronger earthquake activity later but this is not always the case. This earthquake activity is due to inflation of Bárðarbunga volcano after the eruption in Holuhraun in August 2014 to February 2015. This earthquake was in its normal place in north-east part of Bárðarbunga volcano.

This activity is normal and does not signal any eruption risk because after the eruption of 2014 and 2015 it is going to be a while until next eruption happens in Bárðarbunga volcano, probably.

Strong earthquake in Bárðarbunga volcano during the night

During the night of 20-April 2020 a magnitude Mw4,8 earthquake took place in Bárðarbunga volcano. This activity is normal and this is the strongest earthquake in Bárðarbunga volcano since January 2020 when a magnitude Mw4,8 earthquake took place. Article on that earthquake can be found here.

This is how the earthquake was recorded on my geophones.

The traces show that there was a lot of ground displacement in this earthquake. This is due to the inflation taking place in Bárðarbunga volcano and the fact Bárðarbunga volcano collapsed during the 2014 – 2015 eruption in Holuhraun.

Earthquake in Bárðarbunga volcano 15. February 2020

Today (15. February 2020) a magnitude Mw3,6 earthquake took place in Bárðarbunga volcano. There has not been any earthquake activity in this area since this earthquake took place.

This earthquake shows that Bárðarbunga volcano is slowly inflating again after the eruption in Holuhraun 2014 to 2015.

Earthquake in Bárðarbunga volcano

Today (26-January-2020) at 14:25 UTC an earthquake with magnitude of Mw3,7 in Bárðarbunga volcano. This was a single earthquake but that does not rule out a second earthquake in Bárðarbunga volcano is going to happen in next few hours. That might not happen since a second earthquake doesn’t always appear.

This earthquake shows that Bárðarbunga volcano continues to inflate at fast speed. When next eruption is going to happen is impossible to know but shortest time between eruptions in Bárðarbunga volcano is just 3 to 8 years.

Magnitude Mw4,8 earthquake in Bárðarbunga volcano

I hope everyone had good Christmas and good new year 2020.

Today (05-January-2020) at 04:32 UTC an earthquake with magnitude Mw4,8 took place in Bárðarbunga volcano. Second earthquake with a magnitude of Mw4,0 took place at 04:56 UTC. Other earthquakes that took place were smaller in magnitude. This are among the strongest earthquakes in Bárðarbunga volcano since the end of the eruption in Holuhraun in 2015.

This earthquake activity was at the same location as most of this earthquakes happen in Bárðarbunga volcano. At the north-east part of the Bárðarbunga volcano top caldera. This is also close to the locations were the hydrothermal activity at this location has melted though the glacier.

I was unable to record this earthquake because of GPS time rollover error in my GPS clocks that I use and it affects the software I use and time stamps on the recorded events. I need to do a software update on the GPS clocks before I can use them again. I am going to do that in late February or early March. I need to update every GPS clock that I own.

Moving back to Iceland

It has turned out that my income gap is because I am living in Denmark and there’s nothing I can do about it (lowering costs didn’t work as I hoped). Because of this I am moving back to Iceland permanently. I am going to stay in Europe (Germany?) for time to time but I am going to be permanently living in Iceland because of this.

Magnitude Mw3,8 earthquake in Bárðarbunga volcano (01-December-2019)

On 01-December-2019 a earthquake swarm took place in Bárðarbunga volcano. There were two magnitude Mw3,0 earthquake in this earthquake swarm and one magnitude Mw3,8 earthquake. Few smaller earthquakes also took place in this earthquake swarm.

This earthquake activity is now normal for Bárðarbunga volcano and has been going on since the end of the Holuhraun eruption in February 2015. More of this earthquake activity can be expected to happen without any warning. This does not mean that an eruption is on the way in any imminent future.

I am sorry for how late this article this.

Earthquake activity in Bárðarbunga volcano

The regular earthquake activity in Bárðarbunga volcano continued today (24-November-2019) early this morning. Two earthquakes larger than Mw3,0 took place. The first earthquake had a magnitude of Mw4,0 at 04:22 UTC and the second earthquake had a magnitude of 04:28 UTC and had a magnitude of Mw3,5. This earthquake activity happens due to inflation of Bárðarbunga volcano. This is a regular earthquake activity in Bárðarbunga volcano and is it is going to be like this for the next 10 to 30 years. With occasional magnitude Mw5,0 or larger earthquake happening in that time period.

This earthquake activity is not going to result in a eruption of Bárðarbunga volcano since this is too little earthquake activity for that too happen. This earthquake activity shows that an eruption is going to happen in next few years but when that happens is impossible to know.

Strong earthquake and deep earthquake swarm in Bárðarbunga volcano

On Saturday (26-October-2019) a earthquake with a magnitude of 3,5 took place in Bárðarbunga volcano. This was a single earthquake and no more earthquake activity happened following this activity.

On Sunday (27-October-2019) a earthquake swarm started in Bárðarbunga volcano. This is a deep earthquake swarm with a depth from 20,2 km and up to 10,9 km on Sunday. All of the earthquakes in this swarm had a magnitude lower than Mw2,0.

Today (Monday 28-October-2019) the deep earthquake swarm continued in Bárðarbunga volcano. This earthquake swarm was larger in number of earthquakes happening. Depth was from 26 km to 15,5 km. This deep earthquake activity is connected to magma injection from deep magma reservoir that is below Bárðarbunga or a different one nearby. There is no way to know for sure what magma reservoir is feeding this earthquake activity. Often this deep earthquake activity is followed by a more intense earthquake activity in Bárðarbunga volcano it self. What the connection between those two events is remains a mystery. It is impossible to know if this increased earthquake activity means anything for now. Last times this has happened it has not resulted in anything other than earthquake activity over time period of several weeks.

This earthquake activity is now a common feature of Bárðarbunga volcano. This does not mean that an eruption is going to happen soon or is imminent since magma on the move to start an eruption is going to result in a far larger earthquake swarm than have been happening now.
