However there may be nonetheless “great uncertainty”, he added. “Will there be an eruption and if that’s the case, what kind of injury will happen?”

“At this stage, it’s not attainable to find out precisely whether or not and the place magma may attain the floor,” the IMO stated.

Earthquake exercise at Fagradalsfjall decreased over the weekend, which “signifies {that a} new part of magma intrusion is happening”, stated Dr Margaret Hartley, lecturer in Earth Sciences at Manchester College.

Earlier earthquakes within the areas had been “all preceded by decreases in seismic exercise, so this is not essentially a sign that the volcanic unrest is dying down”.

On Tuesday, the Icelandic authorities judged the chance has briefly eased sufficient to permit Grindavik’s inhabitants to briefly return house – escorted by search and rescue groups – to gather pets and belongings.

Dr Dave McGarvie, a volcanologist with the College of Lancaster stated: “The volcanoes on the Reykjanes Peninsula would not have the flexibility to provide the disruptive ash clouds that characterised the Eyjafjallajokull 2010 eruption.”

Classes had been learnt from that occasion, he stated, and even an an identical eruption wouldn’t be so disruptive now.
