This time around, it appears my break is going to a shorter then I planned. According to the newspaper named DV (a short of tabloid in Iceland) there have been a lot of explosion heard from Eyjafjallajökull volcano. According to the news this started around 19:00 UTC, when exactly is unclear at present time.
This was reported by a local farmer in the area, how describe this as the same noise before it started to erupt there Eyjafjallajökull volcano started to erupt in April 2010. But according to Icelandic Met Office and the University of Iceland nothing special has appears on seismometers around Eyjafjallajökull volcano. But it is good to know that in the first eruption in Eyjafjallajökull volcano on Fimmvörðuháls it took few hours for the harmonic tremor to appear following that eruption. For now all that can be done is to wait and see what happens next. This might be a start of a new eruption, or this simply might be nothing for the moment.
Update 1: This has been confirmed by more news media in Iceland. This also appears to have been going on all day. But the explosions today might have been at lower noise level during the day then happened tonight (this is unclear at the moment however). But also according to the news this explosions have been heard to Hvolsvöllur in the right wind direction (or a good weather?). This explosive booms have also been heard by other people in the area around Eyjafjallajökull volcano.
