Noxious gases from an Icelandic volcano threaten to pollute the air of a nearby village and risk spreading to the administrative centre Reykjavik, the Icelandic Meteorological Office (IMO) said on Friday.

The elements agency said it expected particularly heavy gas pollution in Vogar, a village of some 1,000 inhabitants about five kilometers (three miles) northeast of Fagradalsfjall, the uninhabited valley where in fact the volcano is situated.

It said the pollution could reach Reykjavik, 40 kilometers from the volcano, by Saturday.

Concentrations of sulphur dioxide could are as long as 2,600 microgrammes per cubic meter, an even considered “unhealthy for the sensitive”, based on the Environment Agency of Iceland.

However the IMO warned that their models were uncertain because the “flow from the eruption is quite uneven”.

The warning came after measurements showed that activity had halved at the volcanic fissure, which includes been spewing glowing lava since Wednesday, and that along the crack had shrunk from a short 360 meters (1,181 feet) to around 130 meters.

Although stronger than a previous eruption in exactly the same area this past year, the original lava flow of around 32 cubic meters (1,130 cubic feet) per second had decreased by the next day to around 18 cubic meters per second, in accordance with an assessment published late on Thursday.

“This behavior is quite similar to what’s usually observed during eruptions in the countrythe eruption is powerful in the beginning and subsides,” the Institute of Earth Sciences said in a statement.

The field of lava from the eruption covered 144,000 square meters on Thursday.

“The (lava) flow is strongest in the center of (the fissure) and you can find indications that it could extend northwards,” authorities warned.

The pressure in the tunnel feeding the eruption isn’t balanced, which geophysicists say may lead to a fresh eruption at a fresh location.

“New fissures can open in the immediate vicinity of the eruption site with little notice,” the IMO said.

Visitors have flocked to the in record numbers to marvel at the of .

In accordance with authorities, a lot more than 4,200 people walked the 14-kilometer round visit to the website on the Reykjanes peninsula in southwest Iceland on Thursday, about two hours from the nearest carpark.
