Iceland volcano 2023: How likely is an eruption and will it affect travel?

Icelandic authorities have declared a state of emergency after hundreds of small earthquakes have rocked the Reykjanes Peninsula - the island nation’s most populated region - for more than two weeks.

Though seismic activity calmed down on Monday, experts still fear an imminent volcanic eruption and authorities have evacuated almost 4,000 people from a town located nearby.

Despite lying just 10 miles north of the eruption site, Keflavik International Airport - Iceland's main international airport - has not been closed and flights are still arriving and departing.

If you are planning on travelling to or from the affected area, here are the full details on advice from European governments and which airlines are still operating flights.

Iceland’s seismic activity began in an area just north of Grindavik, a fishing town of 3,400 people, which was evacuated on Saturday.

A magma corridor beneath the surface now stretches 15 kilometres from just northwest of the town out into the Atlantic Ocean, according to the Civil Protection Agency. 

Monitoring suggests that this mixture of molten and semi-molten rock is moving closer to the surface meaning an eruption could be imminent. 

"The biggest earthquakes originated there, under this old series of craters, but since then [the magma corridor] has been getting longer, went under the urban area in Grindavík and is heading even further and towards the sea," geology professor Pall Einarrson, told Iceland's RUV.

In and around Grindavik, the seismic activity has already caused large cracks to appear in roads and golf courses.

Concerns have been raised over the impact seismic activity and potential eruption will have on travel.

A major eruption in Iceland in April 2010 caused widespread disruption to
