One geologist told in the news that this eruption had erupted everything that Fimmv\u00f6r\u00f0uh\u00e1ls eruption did in it&#8217;s time around 12:00 today (If my memory is correct on this).<\/li>\n<li>The lava field continues to grow. I am not sure about exact size at the moment.<\/li>\n<li>Pressure in the dyke appears to be high. This might result in more fissure eruption and there is a high risk that some of them might open up under the glacier. More is going to be known tomorrow if the dyke pressure is changing.<\/li>\n<li>Northern part of the fissure is more active than the south part. Part of the fissure has\u00a0 closed and is not erupting any more. That might change without warning if the eruption gains more strength.<\/li>\n<li>This eruption is might continue to for weeks or even moths.<\/li>\n<\/ul>\n<p>If there is any sudden change I am going to post information soon as I can.<\/p>\n<p><strong>News bits<\/strong><\/p>\n<p><a href=\"http:\/\/www.ruv.is\/frett\/close-up-view-of-fresh-icelandic-lava\" target=\"_blank\">Close-up view of fresh Icelandic lava<\/a> (R\u00fav.is)<br \/>\n<a href=\"http:\/\/www.ruv.is\/frett\/gosid-enntha-nokkud-kroftugt-loftmyndir\" target=\"_blank\">Gosi\u00f0 enn\u00fe\u00e1 nokku\u00f0 kr\u00f6ftugt &#8211; loftmyndir<\/a> (air video, R\u00fav.is)<\/p>\n<p><strong>Updates<\/strong><\/p>\n<p>New crater opened up suddenly.
