Lava fountains are pictured at the site of a fissure eruption near Iceland's Bárðarbunga volcano on 2 September 2014. A fissure eruption near Iceland's Bárðarbunga volcano was still spouting lava but no ash, a day after an eruption that briefly caused the country to raise its ash alert level for aviation to its highest level. Iceland's largest volcanic system - 190km long and up to 25km wide (118 miles by 15.5 miles) - has been hit by thousands of earthquakes over the last two weeks, putting scientists have been on high alert.Reuters 
The lava flows on the ground after the Bárðarbunga volcano erupted again on 31 August 2014. Scientists estimate the fissure to be at least 1.5km 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, saying a fresh fissure eruption in Iceland's Bárðarbunga volcano system was not creating ash.Reuters

Picture shows magma along a one-km-long fissure in a lava field north of the Vatnajokull glacier, which covers part of Bárðarbunga volcano system on 29 August 2014. The eruption is at the tip of a magma dyke around 40km from the main Bárðarbunga crater and activity subsided to relatively low levels after peaking between 00:20 and 02:00 GMT, Iceland Met Office seismologist Martin Hensch said.Reuters

General view of the Bárðarbunga volcano in the north-west region of the Vatnajokull glacier on 19 August 2014. The threat of an eruption of Iceland's Bárðarbunga Volcano has increased, according to the Icelandic Meteorological Office, with 'intense seismic activity' and 'ongoing magma movement' reported at the site of the volcano. The heightened activity around the volcano which began with an earthquake, was the strongest earthquake in the area since 1996. The aviation colour code, used to indicate the level of risk a volcano poses to air travel, has been changed to orange, the second-highest level the met office said.Reuters
Iceland's Bárðarbunga volcano erupted last week, which banned airline authorities not to fly aeroplanes over the area.
'Red Alert' was issued at the end of last month after the eruption of the volcano, which lies underneath the Vatnajökull Glacier, according to Mail Online.
Though the eruption was small, but implications would not be good for air travel due to the ashes. Earlier in 2010, ash from the Iceland's Eyjafjallajokull Volcano forced Europe's airspace to shut down for six days.
The Huffington Post reports that volcanic ash could damage the aircraft's engines and plane's exterior because ash clouds contains tiny glass particles within it.
Bárðarbunga is Iceland's largest volcanic system and a small eruption could raise flooding fear. The aerial view of the eruption definitely tells why air travel could be in trouble over the area.
