This earthquake activity clearly shows that something is going on in this part of Vatnaj\u00f6kull glacier. It is my unverified opinion that there is a volcano there. Its not documented and map only show a extinct volcano in this area. This is unlikely to be earthquake activity in extinct volcano, its not impossible, what makes this unlikely is that this earthquake activity happens regularly and has been going on since May 2011. There is ice quake activity in this same area, but some of this earthquake activity is both deep and being located in areas with no glacier. If those are not measuring errors or something like that (I find that unlikely in many cases). I don&#8217;t think there&#8217;s going to be an eruption in this area, at least not for a long time if it ever happens. This earthquake activity might have been going on for a lot longer then from May 2011.<\/p>\n<p>&#8211; This is not an registered or confirmed volcano in this area. Unless there&#8217;s an eruption, it might be a long time until a confirmation happens.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Since May 2011 there has been an earthquake activity in mountain called Saftafellsfj\u00f6ll.
