Iceland volcano latest news: Blue Lagoon extends closure as live camera footage shows cracks in earth
A town of 3,600 people has already sunk three feet into the ground.
It comes as a plan has been put in place for a lava diversion away from Grindavik by building earth walls in the event of a volcanic eruption.
Travel advice from the UK foreign office remains unchanged since seismic activity began on Saturday, despite experts warning that the volcano could erupt at any time.
The Icelandic Met Office has recorded 500 earthquakes since midnight, stressing that the ‘probability of an eruption is still considered high’.
Travellers are advised to check local media for updates, and follow the advice of local authorities, on whether to travel to the area.
Grindavik, is home to 3,600 people, and models show a 15-km long magma intrusion, located just northwest of the town.
It is estimated the intrusion is propagating upwards slowly, with magma thought to be 800m, or higher, beneath the surface.
One of Iceland’s biggest bulldozers has been wrangled to help build several kilometres-long walls around infrastructure to protect it from lava flow.
Experts told Metro.co.uk any eruption could last for weeks or even months.
