The probability {that a} volcanic eruption will engulf the fishing city of Grindavik, Iceland, is reducing by the day, officers stated on Friday, whilst they continued to warn that an eruption might nonetheless happen.
Grindavik, with greater than 3,000 folks, was evacuated this month after it was decided {that a} nine-mile-long underground river of magma was shifting beneath the city to the ocean.
Residents are actually allowed to go residence in the course of the day to verify on their properties and belongings, however till scientists give the all-clear, folks can not completely return, Jon Thor Viglundsson, a spokesman for Iceland’s Division of Civil Safety and Emergency Administration, stated.
Seismic exercise has brought about Grindavik to sink and has broken the sewage system. In consequence, the city can not entry chilly water, he stated. “Sewage is a problem, and sewage lines are ruptured,” he added.
Whereas harm to particular person buildings has been restricted, Mr. Viglundsson stated, as a result of Grindavik sits on a fault line, “the damage to infrastructure is great and affects most of the town.”
Since late final month, tens of hundreds of earthquakes have been reported within the Reykjanes Peninsula within the southwestern a part of Iceland, generally greater than 1,000 in a single 24-hour interval. That seismic exercise led scientists to conclude that an eruption could be imminent, and for a lot of the previous couple of weeks, officers warned of an eruption “within days,” putting Iceland in a holding pattern. The emergency degree has since been lowered.
About 300 earthquakes had been detected within the space on Tuesday, adopted by about 100 on Wednesday, in accordance with the Icelandic Met Office, the nation’s climate service, which it stated was “considerably less than in recent days.”
The magnitude of the earthquakes has decreased as properly. If that continues, “the likelihood of an imminent volcanic eruption diminishes with time,” in accordance with the climate service. Nonetheless, it stated, an eruption alongside the underground magma river remained believable.
Iceland has additionally been fortifying an influence plant that provides electrical energy and scorching water to about 30,000 folks, work that was anticipated to take about 30 days to finish. The plant additionally powers the favored geothermal Blue Lagoon spa, which has closed till not less than subsequent Thursday as a precaution.
Iceland, a rustic of fewer than 400,000 folks and about 130 volcanoes, has an extended historical past of seismic exercise. Most of its volcanoes are lively. The nation straddles two tectonic plates, that are divided by an undersea mountain chain that oozes molten rock, or magma. Earthquakes happen when the magma pushes by means of the plates.
If an eruption does happen, it’s anticipated to be a localized occasion that most likely wouldn’t disrupt flights the best way the Eyjafjallajokull volcano did in 2010. Its eruption produced an ash cloud that grounded much of the air travel in Europe.
