Earthquake activity happens mostly when magma is pushing the crust upwards when it flows into the volcano from depth. The earthquake swarm to the south-east of B\u00e1r\u00f0arbunga volcano is more interesting. That is a dyke and it has been in this area for numbers of years already. At the moment this dyke remains at depth of 15 &#8211; 23 km but this increase in activity might be increasing the risk of eruption if it does not quiet down. The increased magma activity in B\u00e1r\u00f0arbunga volcano has increased the earthquake activity in this dyke over the last few months.<\/p>\n<p>There is a high risk of strong earthquakes in B\u00e1r\u00f0arbunga volcano in the next few days to weeks.<\/p>\n<p>What also happened in this earthquake swarm was a high intensity tremor on the mid-band (1-2Hz) during the earthquake swarm. This is highly unusual. What it means is less clear.<\/p>\n<p><a href=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2018\/03\/von-svd-07.03.2018-at-12.22utc.gif\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/icelandgeology.net\/wp-content\/uploads\/2018\/03\/von-svd-07.03.2018-at-12.22utc.gif\" alt=\"\" width=\"640\" height=\"480\" class=\"aligncenter size-full wp-image-7402\" \/><\/a><br \/>\nThe tremor activity (close to the end) on a SIL station close to B\u00e1r\u00f0arbunga volcano. <em>Copyright of this image belongs to Icelandic Met Office.<\/em><\/p>\n<p><strong>Donations<\/strong><\/p>\n<p>Thanks to donations I was able to buy the moving boxes I need to pack my stuff into before I move back to Iceland.
