Icelandic town evacuated over risk of possible volcanic eruption

Residents of a fishing town in southwestern Iceland left their homes Saturday after increasing concern about a potential volcanic eruption caused civil defense authorities to declare a state of emergency in the region.

Police decided to evacuate Grindavik after recent seismic activity in the area moved south toward the town, and monitoring indicated that a corridor of magma, or semi-molten rock, now extends under the community, Iceland’s Meteorological Office said. The town of 3,400 is on the Reykjanes Peninsula, about 31 miles southwest of the capital, Reykjavik.

The meteorological office wrote Saturday there was a “significant likelihood of a volcanic eruption in the coming days,” but that the exact site of a possible eruption was unknown.

“At this stage, it is not possible to determine exactly whether and where magma might reach the surface,” the meteorological office said.

Authorities also raised their aviation alert to orange, indicating an increased risk of a volcanic eruption. Volcanic eruptions pose a serious hazard to aviation because they can spew highly abrasive ash high into the atmosphere, where it can cause jet engines to fail, damage flight control systems and reduce visibility.

A major eruption in Iceland in 2010 caused widespread disruption to air travel between Europe and North America, costing airlines an estimated $3 billion as they canceled more than 100,000 flights.

The evacuation comes after the region was shaken by hundreds of small earthquakes every day for more than two weeks as scientists monitor a buildup of magma some 3.1 miles underground.

Concern about a possible eruption increased in the early hours of Thursday when a magnitude 4.8 earthquake hit the area, forcing the internationally known Blue Lagoon geothermal resort to close temporarily.

In July, a volcanic eruption occurred in the Reykjanes Peninsula, when a fissure broke open between the Fagradalsfjall and Keilir mountains. It marked the third time in three years that Fagradalsfjall had erupted.

“The amount of magma involved is significantly more than what was observed in the largest magma intrusions associated with the eruptions at Fagradalsfjall,” the meteorological office wrote Friday of the latest threat.

The seismic activity started in an area north of Grindavik where there is a network of 2,000-year-old craters, geology professor Pall Einarrson, told Iceland’s RUV. The magma corridor is about 6.2 miles long and spreading, he said.

“The biggest earthquakes originated there, under this old series of craters, but since then it (the magma corridor) has been getting longer, went under the urban area in Grindavík and is heading even further and towards the sea,” he said.
