Earthquake in Bárðarbunga volcano

Yesterday (14. October 2023) an earthquake with magnitude of Mw3,6 took place in Bárðarbunga volcano. This is one of many inflation earthquakes that have taken place in Bárðarbunga volcano since end of the eruption in 2015. This earthquake activity is going to continue for the next 50 to 100 years if nothing changes, but with rate of earthquakes getting lower as the time passes.

This earthquake shows that Bárðarbunga volcano continues to inflate. This is now normal earthquake activity and happens every one to three months, sometimes the time between earthquakes is longer.

Earthquake activity in Bárðarbunga volcano

Today (19. March 2023) at 14:59 UTC an earthquake with magnitude of Mw3,1 took place in Bárðarbunga volcano. This is normal earthquake activity and shows the inflation that is happening in Bárðarbunga volcano is ongoing after the end of the eruption in 2015.

This type of earthquake activity happens once to twice a month with a earthquake close to magnitude five happening every three to four months. This earthquake activity is getting lower with time, it is likely that it is going to take few more years until it completely stops.

Light sized earthquake in Bárðarbunga volcano

Today (21. February 2023) at 08:41 UTC an earthquake with magnitude of Mw4,9 took place in Bárðarbunga volcano. This is because of inflation that is now happening in Bárðarbunga volcano and has been going on since end of Holuhraun eruption in 2015. Earthquakes with this type of magnitude are going to happen once or twice a year until Bárðarbunga volcano is ready for next eruption and that can take decades. There are going to be smaller earthquakes between larger earthquakes. According to the news, this earthquake was felt in Akureyri.

Last time this happened it took 112 years between eruptions in Bárðarbunga volcano. With the quiet period between 1902 and until 2014. Shortest time between eruptions seems to be around 40 years, but most eruptions happen between 90 to 112 years from last eruption. Based on the data from Global Volcanism Program on Bárðarbunga volcano. There is a lot of uncertainty in this data, so this might be shorter from what it looks like in the data.

I’ve switched to using standard definition for earthquake magnitudes, as shown here (Wikipedia). This is for clarification and simplification when I am writing about earthquakes.
