Bang bang Bárðarbunga
I 2014 rejste en gruppe seismologer fra Cambridge University til Island for at studere det vildeste vulkanudbrud i 200 år. Gennem seks måneder var vulkanen Bárðarbunga i udbrud med en kraft svarende til en Hiroshima-bombe – hver andet minut! Bárðarbungas udbrud var ti gange kraftigere end Eyjafjallajökulls i 2010. Hvis du undrer dig over, at pressedækningen af Eyjafjallajökull var mere massiv, så skyldes det nok, at Bárðarbunga ikke sendte en askesky i vejret, som forsinkede 100.000 fly over Europa. Se seismologernes filmoptagelser her. Fascinating stuff.
The lava flows on the the ground after the Bardabunga volcano erupted again on August 31, 2014. Scientists estimate the fissure to be at least 1.5 kilometres long. The lava is estimated to be six to eight metres thick and flowing at a rate of about 1, 000 cubic metres per second. Iceland cut its ash warning level for aviation to orange from red on Sunday, saying a fresh fissure eruption in Iceland's Bardarbunga volcano system was not creating ash. Iceland's largest volcanic system, which cuts a 190 km long and up to 25 km wide (118 miles by 15.5 miles) swathe across the North Atlantic island, has been hit by thousands of earthquakes over the last two weeks and scientists have been on high alert.
