Recent seismic activity at a volcano in Iceland has experts warning there could be an eruption that causes more travel disruption than back in 2010.
Seismologists are monitoring movement beneath the volcano called Katla - reportedly a far bigger threat to air-traffic than the Eyjafjallajokul volcano, which caused flight fiascos across Europe that cost airlines £1.3 billion.
Small earthquakes and tremors around Katla have reportedly been growing in magnitude, moving up from level 3 tremors to a magnitude 4 quake last week, leading seismologists to warn an eruption could be on its way.
Records have shown that Katla usually has a large eruption twice a century, with its last being almost exactly 93 years ago.
Einar Kjartansson, a geophysicist at the Icelandic Meteorological Office, told the Daily Mail:
We've been getting calls recently from people concerned that Katla is about to erupt because it erupted... in 1918 on October 12.
'As scientists we don't see that much of a correlation in the date but there is most definitely increased activity. The question is whether it calms down after this or whether there is an eruption.'
