Iceland evacuates town as volcano concerns rise

Residents of a fishing town in southwestern Iceland have left their homes after increasing concern about a potential volcanic eruption.



Residents of a fishing town in southwestern Iceland have left their homes amid concern about a potential volcanic eruption, which has triggered a state of emergency.


Police decided to evacuate Grindavik after recent seismic activity moved toward the town and monitoring indicated a corridor of magma, or semi-molten rock, now extends under the community.


The town of 3400 is on the Reykjanes Peninsula, about 50 kilometers southwest of the capital, Reykjavik.


"At this stage, it is not possible to determine exactly whether and where magma might reach the surface," Iceland's Meteorological Office said on Tuesday.


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 $US3 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 5 kilometers underground.


Concern about an eruption increased last Thursday when a magnitude 4.8 earthquake hit the area, forcing the internationally known Blue Lagoon geothermal resort to close temporarily.


The seismic activity started in an area north of Grindavik where there is a network of 2000-year-old craters, geology professor Pall Einarrson, told Iceland's RUV.


The magma corridor is about 10 kilometers 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.
