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.
