Iceland volcano update: Eruption could happen with just 30 minutes warning

Huge cracks appear on roads in Icelandic town at risk of volcanic eruption

Authorities fear the Iceland volcano could erupt with just 30 minutes notice as the country’s Meteorological Office (IMO) warned magma may have reached very high up in the Earth’s crust.

Kristín Jónsdóttir, head of department at the Icelandic Meteorological Office, said people will “just have to wait in suspense for the next few days” to see how events play out.

She said the decreasing earthquake activity over the last 24 hours could be a sign that magma has reached very close to the earth’s surface, adding that the scenario is not unlike what was seen prior to a previous eruption in 2021.

Authorities fear they could get as little as “30 minutes notice” before the anticipated volcanic eruption. “All the big signs are already there, so we are looking for the small signs, the signs that say that even though we are monitoring very closely,” Vídir Reynisson, chief of civil protection added.

The Met Office said magmatic gas has been detected at a borehole in Svartsengi, signalling an imminent eruption of the Fagradalsfjall volcano over the coming days, with the town of Grindavik most at risk.


Previous eruptions in Reykjanes

A volcanic system on the Reykjanes Peninsula has erupted three times since 2021, after being dormant for 800 years. Previous eruptions occurred in remote valleys without causing damage.

The first eruption in Mt. Fagradalsfjall started on March 19th, 2021 at 8:45 PM after increased seismic activity dating back to January 2020, say visit Reykjanes.

.The eruption was steady in the valley of Geldingadalir for about six months and attracted tourists to come and visit the spectacle and the eruption was declared as over in December 2021.

An eruption started again in Mt. Fagradalsfjall, in the valley of Meradalir in August 2022 however the fissures opened only 1 km north of the previous eruption site and it lasted three weeks.

The third eruption in three years started on the 10 July 2023 and is still ongoing, report visit Reykjanes

Over 1000 earthquakes since yesterday

Over 1000 earthquakes have struck in the region of the magma intrusion since yesterday, reported the Icelandic Met Office.

The largest quake was magnitude 2.7 near to Hagafell, said the IMO.

In recent days, between 1,500 and 1,800 daily earthquakes have been measured in the region, with the largest event registering magnitude 3.0 last Friday

Explained – Cause of earthquakes and volcanos in Iceland

Iceland lies on the Mid-Atlantic Ridge where the North American and Eurasian tectonic plates move apart at about 2cm a year, Tamsin Mathers a Oxford University professor in Earth sciences told the Independent.

She wrote in the Conversation: “In the Earth’s mantle below ground, where rocks behave like very stiff toffee, the plates can extend continuously.

“But near the surface, the rocks of Earth’s crust are cold and brittle, and they can only stretch by breaking.

“Like pulling the ends of a chocolate bar with a soft interior but a hard shell, the build-up of strain as the plates pull apart is released in bursts as the coating breaks.”

As the plates move apart, both sides move upwards leading to ground defamation (sinking) in some places and rising in other places.

Icelandic Met Office warns of ‘significant crustal uplift’

The Icelandic Met Office has warned of “significant crustal uplift” in the area of Svartseng.

The review of the images by experts comes as Iceland has been recording between 1,500 and 1,800 daily earthquakes in recent days.

When will Iceland volcano erupt and what happens when it does?

As an imminent eruption looms thousands of Iceland residents await their fate as their town could be wiped out within days.

Some 3,400 residents from the town of Grindavik which lies on the path of the expected fissure vent eruption were forced to evacuate, they described the ‘apocalyptic’ scenes of their much-loved home town as they briefly returned to collect their belongings.

Iceland residents told they face months away from home

Experts have revealed the likely eruption site of a volcano in Iceland, as authorities warn evacuees they may not return home for months.

The forecaster said magmatic gas has been detected at a borehole in Svartsengi, signalling an imminent eruption of the Fagradalsfjall volcano over the coming days.

“Hagafell is thought to be a prime location for an eruption,” the forecaster said.

Icelandic authorities race against time to fortify power plant

Authorities in Iceland have ordered the construction of two giant walls to protect a power plant in the event of an imminent volcanic eruption as they fear the situation could change with “little warning”.

One wall was made 26ft high to fortify the Svartsengi power plant, while construction for another 2.4-mile semi-circle wall was underway just above the small town of Grindavik.

Vidir Reynisson, chief of civil protection and emergency management, told The Mirror that their biggest challenge was to save the power plant from the lava.

“We have plans for the electricity but still there is a lot of challenge around the hot water,” he said.

“If we were to put electric heaters in all the homes in the area we would drain the power system just for that.”

Iceland Met Office updates danger zone in new map

The Icelandic Met Office (IMO) on Monday updated its hazard assessment map for the area of Grindavik and Svartsengi based on satellite images.

The danger zone compared to the previous maps has been expanded to include three broad categories.

A very high danger zone measuring about 2-3km across is marked in purple, while the area around it in red denotes high risk and yellow is moderate.

The highest risk zone in the centre of the 15km-long rift is marked with a dashed red line.
