An enormous nine-mile lengthy magma intrusion, simply northwest of Grindavik, has fashioned and is rising, in keeping with specialists, with magma considered as shut as 500 metres from the floor.
Just some days in the past, specialists had been saying that magma was accumulating three miles under floor, however it has now risen a lot nearer, if estimates are right.
‘At this stage, it’s not attainable to find out precisely whether or not and the place magma may attain the floor,’ the Meteorological Workplace mentioned.
The Icelandic Met Workplace knowledgeable police on Tuesday that their new meters had detected elevated ranges of sulphur dioxide, prompting the police chief to evacuate Grindavik.
Benedikt Ófeigsson, a geophysicist on the Met Workplace, mentioned that whereas the quantity of SO2 detected will not be excessive, the rise factors to magma coming nearer to the floor.

‘SO2 will not be launched from magma till very near the floor. It simply means the highest kilometer,’ he mentioned.
The final measurements, from this weekend, had measured magma at a depth of about 800 metres, however Ófeigsson now expects it’s even shallower.
‘We’re speaking about possibly 500 metres. It is unclear, it is so excessive stress, it is stress dependent when it comes up. So it isn’t attainable to inform the depth instantly, however it [the magma] have to be very shallow for us to see SO2 ‘.
Ofeigsson yesterday informed Icelandic broadcaster RUV that there was no indications on different units that an eruption was beginning, however that they nonetheless didn’t wish to rule it out, explaining that SO2 doesn’t seem on this means except magma may be very excessive within the earth’s crust.
Sulphur dioxide is a poisonous gasoline launched by magma because it rises to the floor, and excessive publicity is lethal to people. If detected at a non-erupting volcano, it might be an indication that it’ll erupt quickly.

Whereas the variety of quakes has diminished and tremors are much less violent than in earlier days, specialists have mentioned that this might point out that magma is nearer to the floor and point out an eruption may be imminent.
‘Much less seismic exercise sometimes precedes an eruption, as a result of you could have come so near the floor that you simply can not construct up lots of stress to set off giant earthquakes,’ mentioned Rikke Pedersen, who heads the Nordic Volcanological Centre based mostly in Reykjavik.
‘It ought to by no means be taken as an indication that an outbreak will not be on the best way,’ she mentioned.

In case the worst occurs, authorities are getting ready to construct defence partitions round a close-by geothermal energy plant which they desperately hope will shield it from lava flows.
Iceland’s Justice Minister Gudrun Hafsteinsdottir informed RUV on Tuesday that a big dike has been designed to guard the Svartsengi geothermal energy plant, positioned simply over six kilometers from Grindavik.
Tools and supplies that would fill 20,000 vehicles had been being moved to the plant, she mentioned, and building is awaiting formal approval from the federal government.
The plant produces cold and hot water and electrical energy for all the nation and a spokesperson for its operator, HS Orka, mentioned a disruption wouldn’t influence energy provide to the capital Reykjavik.
Matthew James Roberts, director of the service and analysis division at Iceland’s meteorological workplace mentioned: ‘We imagine that this intrusion is actually hovering, sitting in equilibrium now just under the earth’s floor.
‘We now have this great uncertainty now. Will there be an eruption and if that’s the case, what kind of harm will happen?’

Fears have additionally been mounting that an eruption might see a repeat of the chaos brought on by the 2010 Eyjafjallajokull eruption, nevertheless volcanologists have mentioned that Fagradalsfjall wouldn’t produce as big an ash cloud because it did if it does blow.
The eruption 13 years in the past prompted the most important shutdown of worldwide aviation because the Second World Struggle, with 50,000 flights cancelled and eight million passengers affected.
Discussing the variations between a possible eruption of Fagradalsfjall and Eyjafjallajokull, Mr Roberts mentioned an eruption might see lava spew over the city, however was much less prone to trigger the identical ash blast.
He informed BBC R4’s Immediately programme on Monday: ‘To begin with there is not an ice cap on prime and it isn’t a stratovolcano so would not be an explosive blast of volcanic ash into the ambiance.
‘This could be a lava-producing volcanic eruption alongside a collection of fissures and that will be the principle hazard.’
He added that an eruption ‘that persists for weeks’ is feasible, which means roads and different infrastructure might be ‘in hurt’s means’.
