The lava flows on the ground after the Bardabunga volcano erupted again on August 31. 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-cu-m 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.  Reuters/Armann Hoskuldsson
