Iceland has been cast by the warmth of the Earth’s core.
The molten rock that now sits 800 metres beneath the fishing village of Grindavik is anticipated to achieve the floor inside days, the most recent in an extended historical past of eruptions.
Around 4,000 inhabitants have been evacuated within the early hours of Saturday after a swarm of earthquakes clustered in a small space. There had been greater than 1,000 tremors in only a few hours, brought on by the magma forcing its method upwards.
Scientists consider it has now pooled in a 10-mile tunnel within the rock, stretching from the island inside out to sea.
The Reykjanes volcanic system is barely 35 miles from the capital, Reykjavik. It had been dormant for 800 years till it erupted from a fissure in March 2021. The lava fountain turned a vacationer attraction over a six-month interval.
There have been two extra eruptions in the identical space since then.
But the quantity of molten rock slightly below the floor this time is regarded as far larger.
It’s potential the eruption will probably be simply offshore, during which case the contact between super-heated rock and water can be explosive – with an ash cloud probably being thrown a number of miles excessive.
That can be an echo of the Eyjafjallajokull eruption in 2010, which brought on widespread disruption. Around 100,000 flights have been grounded over a number of days due to fears that plane engines can be broken by the ash cloud that swept in the direction of Europe.
Iceland is among the most volcanic areas on the planet.
It sits on the mid-Atlantic ridge, the place the tectonic plates of North America and Eurasia are pulling aside by 2cm a yr.
Over hundreds of thousands of years, a plume of molten rock poured from the rift, ultimately breaching the ocean floor to type an island.

Volcano close to Iceland’s capital erupts for the second time in a yr
On common there’s an eruption from one among Iceland’s 32 lively volcanoes each 4 or 5 years, with rivers of lava shaping the stark panorama.
Some of the eruptions have been catastrophic.
In 1783 round 1 / 4 of the inhabitants was killed following an eruption of the Laki/Skaftareldar volcano.
The greatest present concern is over Katla, which final erupted in 1918. It lies underneath a whole bunch of metres of ice and any eruption is more likely to trigger widespread flooding.
