Another volcanic outbreak near Grindavík in Iceland. This is the 11th in the last few years on Reykjanes. Luckily it looks like it has calmed down already and I hope it stays calm.

There was lava quite close to town this time.

Here we go again…?

#volcan #volcano #Fagradasfjall Une éruption brève a eu lieu sur une fracture longue de 700m située juste au nord de Grindavik/A short-lived eruption occured on a 700m long fracture just north of Grindavik

Quand la lave du jour s'apprête à rejoindre celle du 14 janvier 2024 (la petite faille qui a cramé 3 maisons). Au fond au milieu, une serre.

Surprenamment, la première fissure ne s'agrandit plus depuis presque deux heures. Elle fait 700 m de long. On est donc loin des 3-5 km des précédentes. La seconde faille continue sur sa lancée, le tout à moins de 500m du quartier nord-est de Grindavik.

Les autorités envisagent le pire : une autre faille qui s'ouvre en pleine ville...

Résumé de la situation en une carte.

C'est pas réjouissant.

“The #eruption fissure that opened shortly before 10am is now 700 m long and has not grown for about an hour.
The 2nd fissure, which opened just inside the barriers shortly before 11am, is considerably smaller but appears to be trying to extend S towards #Grindavík.“

Les huit habitant.e.s resté.e.s à Grindavik refusent de bouger et menacent (dont un type muni d'un flingue) les équipes de sauvetage qui tentent de les déloger.

Nani the fuck !

Edit : c'est bon, toute la ville a été évacuée.

That brand-new top-end greenhouse is going to burn.

Ahhhh... fuck. :(
