We remember well whenLast November 11 a small fishing village Grindavik was evacuated due to seismic swarmsground deformation and real fractures in the groundsignals interpreted as precursors what actually happened next a little over a month.

In fact from tonight from a huge crack in the ground, approx 3.5 kmwhich we can almost define as “extended volcano” he began to escape large amount of magma.

Within Few minutes a line began to appear fountains spouting lava also tall hundreds of meters.

Some details of the spectacular eruption

Due to the size of the volcanic fissure amount of lava he is released notablethey are estimated to leak 100 to 200 cubic meters of lava per second.

it ismainly effusive eruptions which does not happen from the volcanic cone, but behind long fracturefor this reason we speak fissured or linear eruption. The first lava flows began precisely in December 18 at 10:17 p.mfor a little over an hour seismic activity which foreshadowedupcoming event.

L’evacuation the village of Grindavik was providentialactually even though at this moment in “uninhabited” center no magma escapes were noted south cape long eruptive fissures from which it just started eruption, is found only 3 km from the city limits which could still be at this point swept away by lava.

Everything will depend on the direction in which the magma will move: if they head further towards the south it will be for the village very little hope to save themselves if the lava flow pushes forward instead to the north then the country could still have a future and that’s the point 4000 inhabitantsevacuated a month ago, he might once return to their homes.

This is not a rare phenomenon in Iceland

Must emphasize that this type of action It’s not particularly rare in Iceland, which is located right along Mid-Atlantic Rift which divides European plate from that American and the island is right it comes from magma ran away from ocean ridge which separates the two plates. The island itself is completely formed by volcanic rocks.

There are eruptions in Iceland very common and they actually exist 30 active volcanoes which they have also given us in recent years spectacular performances.

As for the last of some measurements it would seem that at this moment the eruption loses intensitywhich doesn’t mean it’s nearing the end at all, but just that the situation stabilizes and enters into equilibrium phase.
