Earthquake swarm on the Reykjanes ridge close to Eldeyjarboða islands [updated]

Today (18-January-2020) at 12:38 UTC an earthquake swarm took place on the Reykjanes ridge close to Eldeyjarboða island. Largest earthquake in this swarm had a magnitude of Mw4,0 according to Icelandic Met Office. Both USGS and EMSC are reporting this earthquake as a mb4,5 in automatic detection. Second largest earthquake had a magnitude of Mw3,8.

Other earthquakes have been smaller in magnitude. This earthquake swarm appears to be over but it is possible that this is just a limited stop in earthquake activity before it starts again. That is a common feature of earthquake swarms in this area. Earthquake can reach magnitude of Mw5,5 in this area of Reykjanes ridge.

Update on 19-January-2020

Icelandic Met Office updated the earthquake magnitudes yesterday and it now shows two Mw4,5 earthquakes taken place at 14:07 UTC and 14:17 UTC and one Mw4,0 earthquake having taken place at 15:52 UTC.

Earthquake swarm close to Hveragerði (South Icelandic Seismic Zone)

Today (10-Januar-2020) at 13:10 UTC a earthquake with the magnitude of Mw3,9 took place just 4,9 km outside of Hveragerði town in south Iceland. This earthquake was felt over a wide area. Several small aftershocks have taken place following the first earthquake.

It is unclear if this earthquake is a foreshock or just normal earthquake for this area. Its been 12 years since two Mw6,3 earthquakes (May 2008) took place in SISZ and the shortest time between earthquakes of this size on SISZ is around 10 to 13 years.

Currently my geophones are offline due to technical issues that I am going to fix in March after I have moved back to Iceland.

Earthquake swarm on Reykjanes ridge (Geirfuglasker area)

Today (5-Januar-2020) an earthquake swarm took place on Reykjanes ridge. Largest earthquake had a magnitude of Mw3,2 at 09:40 UTC and the second largest earthquake had a magnitude of Mw3,1 at 11:19 UTC. Others earthquakes were smaller in magnitude but all of them were stronger than Mw2,0 in magnitude. It is difficult to know for sure if there is going to be a earthquake swarm in this area but the chances are good that is going to happen. It might take few days to weeks until it happens.

At the writing of this article there is no earthquake activity in this area. That might chance without warning.

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.

Update two of the earthquake swarm on Reykjanes peninsula, east of Fagradalsfjall mountain

Today (19-December-2019) at 11:20 UTC a earthquake with magnitude of Mw3,5 took place east of Fagradalsfjall mountain. This earthquake was felt in Reykjavík and nearby area. This earthquake was a continuation of the earthquake swarm that started on 15th December 2019 in this area. The activity has dropped from what was before but it is still ongoing mostly.

There are no other updates about this activity so far. I have been waiting today to see if anything more would be happening and it has not. It might happen later if anything happens at all.

Moving back to Iceland

Living in Denmark just isn’t working for me as I hoped and that is just how it is. That is why I am moving back to Iceland. It is either going to be in February or March depending on factors that I am looking into now (best price for moving my belongings to Iceland). I am not sure yet how I pay for this move since it is going to cost me around 1.091€ to 1.309€. I hope nothing higher than this amount. After this I won’t be moving away from Iceland. I am just going to stay there.

Update on the earthquake swarm on Reykjanes peninsula

I am sorry for this late update.

The earthquake swarm east of Fagradalsfjalla mountain increased again yesterday (16-December-2019). According to a notice on the Icelandic Met Office over 1200 earthquakes have been recorded in this earthquake swarm. Total of 10 earthquakes had a magnitude of Mw3,0 or larger. The largest earthquake had a magnitude of Mw3,7.

This earthquake swarm again seems to be over but it might start again without warning. This earthquake swarm remains tectonic in nature.

Earthquake swarm on Reykjanes peninsula

Today (15-December-2019) an earthquake swarm started this morning at 07:10 UTC and the strongest earthquake had a magnitude of Mw3,5 and other earthquakes have been smaller in magnitude. Around of 190 earthquakes have happened in this earthquake swarm that appears to be over or at least has stopped for now.

This is a tectonic earthquake swarm from the looks of the earthquakes that I have recorded on my geophone. This is probably a rift valley activity in this area. It is not possible to know if this earthquake activity is over or not. It is common that earthquake activity stops for few hours and then resumes at higher activity then before. Sometimes this type of earthquake swarm just stops and doesn’t resume.

Please remember to support my work with donations. I am really broke this month and that has started to create problems for me. If you support me by donating with a bank transfer please update your information since I now send everything to my Icelandic bank, rather than my Danish bank. New bank information can be found here. I do this for simplification and other reasons that I am going to go into later (when feeling less down from all this being broke).

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.

Update on the earthquake swarm on the Reykjanes ridge

The earthquake swarm that started today (16-November-2019) on the Reykjanes ridge in the volcano called Reykjanes [Eldey] continues. At the writing of this article 29 earthquakes larger than magnitude Mw3,0 have happened at this location on the Reykjanes ridge. Largest earthquake so far had a magnitude of Mw4,5. The earthquake swarm slowed down after 17:00 and has remained in slow activity since then but it is ongoing as of writing of this article.
