Iceland Volcanic Eruption Threat Decreases As ‘Magma Dike Solidifies’

A Geophysics professor in Iceland, Magnús Tumi Guðmundsson, shared that the solidification of the magma dike at Svartsengi, a geothermal subject close to Grindavik, by 90% over two weeks has decreased the probability of a volcanic eruption.

Lowered seismic exercise and low tectonic plate reflection contribute to the diminished threat. Whereas Guðmundsson emphasizes a possible eruption can’t be completely dominated out, he deems it much less seemingly. 

Considerations of a Grindavík eruption following an earthquake on November 10 have eased, with no indicators of magma accumulation. 

Probability Of Iceland Eruption Is Decrease As ‘90% Of Magma Dike’ At Svartsengi Solidifies

Based on Guðmundsson, a geophysics professor on the College of Iceland, the solidification of the vast majority of the dike at Svartsengi, near the city of Grindavik, has led to a lower within the probability of a volcanic eruption.

Talking to the Iceland MonitorGuðmundsson likened the magma’s decomposition on the edges of the magma channel to “water that’s put inside a fifty-degree frost.”

He defined: “This doesn’t preclude that there’s nonetheless one thing left and that there’s nonetheless an open means the magma might go upwards, if extra magma accumulates. However the probability of an eruption has turn into significantly decrease than it was, amongst different issues, due to this.”

The decreased probability of an eruption is attributed to the dike’s 90% solidification over the previous two weeks, per the publication.

‘A New Course of Can Begin In The Close to Future’ 

As acknowledged by the geophysicist, the decreased seismic exercise within the space, coupled with the low tectonic plate reflection, has contributed to a decreased probability of an eruption.

Nonetheless, he emphasizes that the opportunity of an eruption can’t be completely dominated out, stating: “There isn’t a strategy to exclude that there will likely be an eruption. The most probably space is in the midst of the dike, east of Sýlingarfell mountain.”

“This naturally solely applies to the present state of affairs. A brand new course of can then begin within the close to future,” Guðmundsson pointedly added, noting that though magma continues to stream right into a storage chamber beneath Svartsengi, there’s minimal pressure and earthquake exercise.

Worries Of Iceland Volcanic Eruption Ease, ‘No Indicators Of Magma Accumulating’ In Grindavík

Beforehand, there have been considerations a couple of potential eruption in or close to Grindavík following a major earthquake on November 10 that resulted within the fishing neighborhood being evacuated. A fissure was fashioned following the earthquake, however there’s reportedly no signal of magma accumulation.

Geophysicist Guðmundsson clarified that there are not any present indicators indicating an eruption will start within the fissure, particularly stating, “There are not any indicators of any magma accumulating in Grindavík itself.”

He shared that though the land rise at Svartsengi has barely decelerated, it’s deemed inconceivable that it’ll attain the identical stage by the top of the month as on November 10.

Guðmundsson highlighted potential situations, stating: “There are a number of situations. One is that the land rise will proceed below the Svartsengi at a major price and in just a few weeks there will likely be a state of affairs much like that which existed earlier than this occasion.”

He continued: “The opposite factor is kind of clear, nevertheless, that strain can’t construct as much as the identical extent because it was earlier than. There’s now a weak spot the place the tunnel is, and though it’s largely solidified, there’s nonetheless, in all probability, a connection [where the magma flows upwards].”

He concluded by emphasizing the unlikelihood of heavy strain rebuilding beneath Svartsengi as a result of weakened roof, including, “The roof has been damaged and it takes months or years earlier than it reaches its earlier power. Despite the fact that it has been deconstructed, it’s weak.”

Iceland Protection Partitions Can Supply Safety To Properties

Based on Guðmundsson, there’s no absolute assurance that protection partitions being constructed will safeguard all the pieces, however they will provide substantial safety to quite a few houses and invaluable property.

He famous the advanced nature of coping with pure forces and acknowledged the inherent dangers related to harnessing geothermal power in Iceland regardless of its important advantages.

Guðmundsson advised a possible resolution, proposing the connection of scorching water from Reykjavik to the Suðurnes area. He stated: “If the Svartsengi energy plant was to be discontinued, then the pipeline from the Reykjavik space might maintain Suðurnes, Keflavík Airport, Keflavík and these areas working.”

“A city like Reykjanes relies on getting energy and warmth from an influence plant that will be destroyed or broken by a volcanic eruption. This sort of connection would save all the pieces,” he famous, per the Iceland Monitor.

Government Officials say the “probability of an imminent volcanic eruption diminishes with time.” Nonetheless, native residents will nonetheless stay in momentary houses as a result of seismic actions, that are reducing however proceed to occur.
