Bardarbunga shaken by double earthquakes over 5 magnitude – volcanic pressures intensifying beneath glacier

August 2014ICELAND – Two earthquakes measuring over 5 in magnitude — the biggest yet — shook Iceland’s Bardarbunga volcano Sunday after the country issued an aviation red alert warning that an ash-emitting eruption may be imminent. Iceland’s Meteorological Office recorded earthquakes of 5.3 and 5.1 in the early hours. It said there were no signs of an eruption. The volcano, underneath Iceland’s vast Vatnajokull glacier, has been rattled by thousands of small earthquakes over the past week. On Saturday scientists reported a small eruption under the ice, but it was not visible on the surface, and the Met Office later said it appeared to have stopped. Authorities have declared a no-fly zone of 100 nautical miles by 140 nautical miles (185 kilometers by 260 kilometers) around the epicenter as a precaution. 
 A 2010 eruption of Iceland’s Eyjafjallajokul volcano caused a week of international aviation chaos, with more than 100,000 flights cancelled. Aviation officials closed Europe’s air space for five days out of fear that volcanic ash could harm jet engines. Any new eruption is likely to be less disruptive. European aviation authorities have changed their policy, giving airlines detailed information about the location and density of ash clouds but leaving decisions to airlines and national regulators. Britain’s National Air Traffic Service said it was monitoring what it called a “dynamic situation” but was expecting normal operations Sunday. –ABC News
Eruption has begun: Iceland’s Meteorological Office says a small lava eruption has begun underneath a glacier at the Bardarbunga volcano, the Associated Press reports. Seismic data showed ice melting beneath the Vatnajokull glacier, but it remains unclear if or when the eruption would break through the ice, sending ash and steam into the air. On Saturday, the agency changed the aviation alert for the volcano from orange to red, a move that signals an eruption is either imminent or already in progress. The country also put its Coast Guard on alert, Bloomberg reports. Earthquakes had been happening “so quickly that it is difficult for the seismologist to discern individual events,” a statement on the Met Office’s web site reads. As concern increased last week over a possible eruption of Iceland’s Bardarbunga volcano, authorities evacuated tourists from area.

Iceland’s Civil Protection Department says 300-500 people, mostly visitors, have been evacuated from the highlands north of the Vatnajokull glacier, which is popular with hikers. Officials said Wednesday the measure was taken as a safety precaution, the Associated Press reports. Roads in the area have been closed in the event that an eruption would lead to flooding. Air travel experts are also watching the situation closely. The volcano sits in a major flight path from the U.K. to North America, and an eruption would cause chaos. –Weather Channel

    Just a quick question, is the name Baroabunga or Bardabunga? Or can it be both? At least it isn’t Eyjafjallajökull. But either way, this will not be good when it blows.

    There has been some deflation in the caldera. In two words – Not Good. Hopefully this doesn’t continue. Look up “caldera collapse” to examine the consequences. A caldera collapse coupled with the enormous amount of glacial ice contained within could produce a huge eruption.
    This caldera produced the largest eruption of the Holocene – that is the present era starting as from 11,700 years ago.

      I did. I went to the Royal society publishing.org site and as you said “not good”

      I did a phrase search “consequences of Caldera Collapse”.

    Ok so what would this eruption mean for the US? It’s not a supervolcano right? Should we expect effects from the ash here? I can’t believe how quickly events are happening now.

    With all the recent activity of earthquakes and volcanos erupting are we gaining pace of a pole shift rather then climate change? The earths core is magnetised molten iron ore and any movement from north to South could cause the earths mantel to buckle and move hence earthquakes and pressure release eg: this volcano about to erupt?

    In the short term, the longer this volcano does not erupt, the more serious the eruption will be. Look for a series of magnitude 5s, or greater.
