A hydrothermal activity was seen on top of B\u00e1r\u00f0arbunga volcano caldera. Since the eruption in Holuhraun ended in February-2015 this hydrothermal activity has dropped, it has increased if anything. At the moment there are several depressions in the Vatnaj\u00f6kull glacier that is on top of B\u00e1r\u00f0arbunga volcano. Largest of them are 400 meters wide, I am not sure about their length. This cauldrons are around 100 meters deep and for the first time in several hundreds of years have exposed a bed rock that is normally under the glacier. Hydrothermal activity in B\u00e1r\u00f0arbunga volcano is now such that is able to melt 100 meters of glacier in several months.<\/p>\n<p>This high amount of hydrothermal activity in the main volcano increases my suspicion that B\u00e1r\u00f0arbunga volcano is far from over. Since this also means that fresh magma is reaching up to 1 km in the crust in the B\u00e1r\u00f0arbunga volcano caldera rim. I don&#8217;t have any map of the locations of the calderas at the moment since none exist or at least has not yet been published. The main concern now is that this is going to increase the risk of sudden glacier floods from B\u00e1r\u00f0arbunga volcano. This might also increase the risk of sudden short volcano eruptions in B\u00e1r\u00f0arbunga volcano, either in its slopes or close to the caldera rim. As it is clear that magma has rather clear access to that part of the volcano.<\/p>\n<p><strong>R\u00fav News article (in Icelandic)<\/strong><\/p>\n<p><a href=\"http:\/\/www.ruv.is\/frett\/gat-i-gegnum-jokulinn\" target=\"_blank\">Gat \u00ed gegnum j\u00f6kulinn<\/a> (R\u00fav.is, Icelandic, video)<\/p>\n<p><strong>Donations<\/strong><\/p>\n<p>Please remember to support my work with donations.
