Authorities are warning residents of the Icelandic town of Grindavik that it may be months before they are able to return to their homes as volcanic eruption concerns persist.

Grindavik, which was evacuated by the Icelandic government this week after seismic activity and air content analysis pointed to possible eruptions, has been shut down to traffic for the foreseeable future.

Residents have only been given short windows of time to gather their belongings and flee the town, which is believed to now sit on a corridor of magma flowing under the area.

The Icelandic Meteorological Office said since midnight yesterday, around “800 earthquakes have been measured, most of them in the middle of the magma dyke at Sundhnúk at a depth of about 3-5 km [1.8 to 3.1 miles].” 

“Seismic activity has remained constant since 11th of November. The main monitoring focus on seismic activity remains in the area of the dyke and Grindavík,” the Icelandic Meteorological Office said.

Sundhnúk is a little more than 2 miles to the north-northeast of Grindavík.

Video and images also have emerged appearing to show smoke rising out of cracked roads in Grindavík in recent days.

Iceland sits in the middle of the Mid-Atlantic Rift, which makes it a hotbed for geothermal activity. There are over 130 volcanoes here, as well as a variety of geysers and volcanic fissures.

Iceland is a Nordic nation. The first people said to have explored the island were Vikings from Norway, who settled here as early as the ninth century.

Norwegian societies created an Icelandic Commonwealth, which eventually fell under Danish rule. 

Iceland became an independent republic in 1944.
