I get even stranger emails at times (no, I <strong>don&#8217;t<\/strong> answer those). Far as I know there isn&#8217;t any <a href=\"http:\/\/en.wikipedia.org\/wiki\/Felsic\" target=\"_blank\">Felsic magma<\/a> (or <a href=\"http:\/\/en.wikipedia.org\/wiki\/Andesite\" target=\"_blank\">Andesite<\/a>) in B\u00e1r\u00f0arbunga volcano caldera. Reason for that is it appears to have been really long time since the caldera erupted. I am not sure on exact time scale, but it is from 400 to 700 years at the shortest. The forces at work in B\u00e1r\u00f0arbunga volcano are extremely complex and they are not properly understood today, the eruption in B\u00e1r\u00f0arbunga volcano is going to add that knowledge with time. Since it is going to take many decades of study to analyse and figure out what the data collected today means. I dismiss all strange and odd ideas about what is going on in B\u00e1r\u00f0arbunga volcano, since they don&#8217;t fit the data that I am seeing (along with <em>everyone else<\/em> that is viewing that same data, interpretation of that data <em>might<\/em> differ)<\/p>\n<p>It is also worth to mention that only north part of the B\u00e1r\u00f0arbunga volcano system has shown rifting in only one fault. There are many more in this area that have not yet moved. I expect them to move in next few months to years. Then there is the matter of all the activity that is going to take place in B\u00e1r\u00f0arbunga volcano south of it. That area has not moved so far, it is going to rift in the same manner as the area in the north of B\u00e1r\u00f0arbunga volcano. When is impossible to know, but I expect it to happen in next few months to years. This is far from over, in fact, this activity in B\u00e1r\u00f0arbunga volcano has <em>barely started<\/em>, even if it has been erupting now for almost one month and a half. There are going to be quiet period with no eruption activity in B\u00e1r\u00f0arbunga volcano during this process. Those quiet periods are going to be different in length, they are <em>going<\/em> to happen, it is just a matter of time. That is how rifting works in <a href=\"http:\/\/en.wikipedia.org\/wiki\/Rift_zone\" target=\"_blank\">rifting zones<\/a> (and <a href=\"http:\/\/en.wikipedia.org\/wiki\/Rift_valley\" target=\"_blank\">rift valley<\/a>) around the world.<\/p>\n<p>Next update is tomorrow if nothing major happens in B\u00e1r\u00f0arbunga volcano.<\/p>\n<p><em>Article updated at 01:09 UTC on 07-October-2014.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This information is going to get outdated quickly.
