The earthquake activity close to \u00deorbj\u00f6rn might be a mixed earthquake activity of tension breaking earthquakes and magma pushing it self up. GPS data doesn&#8217;t show any inflation close to \u00deorbj\u00f6rn mountain at the writing of this article.<\/p>\n<p>Earthquake activity is increasing in south part of Fagradalsfjall volcano, this is area in N\u00e1tthagi, N\u00e1tthagakriki and other nearby area. There is a dyke intrusion in that area and has been a while. That dyke intrusion might be about to erupt. There is a lot of uncertainty going on at the writing of this article. There is also a pattern of high and low in the earthquake activity, this has been the pattern in the earthquake activity before the earlier eruptions.<\/p>\n<p>I&#8217;ll write updates about this activity as needed.
