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.
