During the weekend activity in B\u00e1r\u00f0arbunga<\/a> volcano was in the same manner as it has been for the past two months. Largest earthquakes during the weekend had the magnitude of 5,2 and 5,3. Pollution was a big problem south of the eruption in Holuhraun and new record was set for SO2 pollution in populated areas in Iceland. The pollution levels did go up to 21.000 \u03bcg\/m3 when they where the highest during the weekend. A emergency was declared for H\u00f6fn in Hornafir\u00f0i when the worst pollution did go over the area. Currently there is a little bit less pollution, but air quality is poor in parts of south Iceland at the moment.<\/p>\n

Largest earthquake on 27-October-2014 had the magnitude of 5,3 and happened in the south-east part of the caldera. Since it has been quiet in terms of earthquake activity. According to Icelandic Met Office this is normal and has happened before. Subsidence of the caldera happens without<\/strong> any earthquake activity most of the time. According to Icelandic Met Office and others (pdf file here<\/a>), the caldera has now dropped some 40 meters. New cauldrons have been forming along the caldera rim and older ones (that I did not know about until today) have been getting deeper according to measurements from Friday (24-October-2014). The new and older cauldrons appear clearly on images that can be found here<\/a> (text is in Icelandic). GPS data<\/a> is showing minor inflation in the dyke that is currently erupting, suggesting that more magma is flowing into it then is erupting from it.<\/p>\n

If any<\/strong> melt is happening in the caldera it is not appearing on the glacier yet. As for the water, it just goes down. Rock inside volcanoes leaks, a lot, so it is easy for the water to go into the crust. It doesn’t have to go anywhere else in small amounts that might<\/strong> be melting if the crust has warmed up enough to do so. Currently there are no evidence for that taking place, but with 850 meters of glacier on top of it is difficult to be sure. There are no other news about the eruption that I know of at the moment.<\/p>\n
