This is because of inflation that is now happening in B\u00e1r\u00f0arbunga 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 B\u00e1r\u00f0arbunga 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.<\/p>\n<figure id=\"attachment_10949\" aria-describedby=\"caption-attachment-10949\" style=\"width: 540px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-10949 size-full\" src=\"https:\/\/icelandgeology.net\/wp-content\/uploads\/2023\/02\/230221_1300.png\" alt=\"Green star and red dots in B\u00e1r\u00f0arbunga volcano inside Vatnaj\u00f6kull glacier.
