Tonight, nearly 4,000 people forced to evacuate in Iceland after hundreds of intense earthquakes shook this fishing village early this morning, leading to massive cracks opening up on the streets and in homes. The quakes, a warning sign of a looming volcanic eruption as a mile-long pool of lava below the town threatens to erupt. Local resident Gizley Gunnerson, and his girlfriend caught one of the strongest quakes on camera.

This is a very big lava pocket, and it goes straight under the tom. So the tom could just disappear.

Closing down the nearby Blue Lagoon, one of the country's most popular tourist destinations, and raising the aviation alert to orange. In 2010, an enormous ash cloud from the eruption of an ice-capped volcano grounded flights across Europe for weeks. The region dormant for 800 years came back to life in 2021. Magma bursting to the surface again last year and this summer. What an impact will that have? Even a smaller eruption.

We are looking at people losing their homes and particularly other critical infrastructure. There's a power plant, there's the Blue Lagoon. At the moment, magma is so close to the surface that it could come up in a matter of potentially minutes. So it could happen in the next hours. It could happen in the next few days. We just don't know.

The people from this fishing village watching and hoping their town survives. There's still a lot of uncertainty today, but even a small eruption could cause a lot of damage, according to scientists in Iceland. But they say it won't create an ash cloud like the one that grounded flights back in 2010. Thanks for watching.
