Eruption underway on the Reykjanes Peninsula
A magma outflow from the magma corridor began in the Sundhnúkur crater area at 6:30 AM.
A volcanic eruption began just before 9:45 AM.
It is the eighth eruption in the Sundhnúkur crater row.
The evacuation of Grindavík took place earlier today.

Quand la lave du jour s'apprête à rejoindre celle du 14 janvier 2024 (la petite faille en bas à gauche et qui a cramé 3 maisons). Au fond au milieu, une serre.
En direct de Keflavik. La météo est vraiment pas top : nuageux et beaucoup de vent, ce qui fait que le panache de fumée n'a rien d'impressionnant.
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.
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. :(
(New #Iceland #volcano #Eruption near #Grindavík, and it's past the protective berm....)
There's a new eruption started in #Iceland. The fissure is really close to the town of Grindavík.
See the Icelandic Met Office web page for official information.

Apparition d'une seconde faille.
Toujours du mauvais côté de la barrière défensive de Grindavik.
Shit-bis.
Shit ! C'est à l'intérieur de la barrière défensive au nord-est de Grindavik....
Let's go !
Short update - Mt Etna, Sicily - 29.03.2025
In the last 14 days, further Strombolian episodes have occurred at the South East Crater of Mt Etna:
Accompanied by strongly increasing tremor, weak Strombolian explosions were visible at the former saddle vent of the South East Crater on the evening of 19 March. The vent located above the large southern breach continued to increase its activity until midnight and finally powerful Strombolian explosions hurled glowing material onto the southern and eastern flanks of the New South East Crater cone. Further vents on the upper north-west flank of the cone also became active. After about 02:30 the intensity of the explosions decreased again and at sunrise the activity was already significantly reduced.
A similar episode began on the morning of 24 March, but it took place in very bad weather. The fading Strombolian activity at the South East Crater could only be observed in the evening.
Another Strombolian episode is likely to have occurred on 28 March, as the tremor again increased sharply for a few hours, but dense clouds and fresh snow prevented any observation via webcams.
This INGV-webcam photo shows the Strombolian activity at the South East Crater on the morning of 20 March. The explosions that began the evening before have already weakened:

Short update - Mt Etna, Sicily - 16.03.2025
After almost 14 days of quiet gas emission at the summit craters, mild Strombolian activity suddenly began at Mt Etna's South East Crater on the evening of 15 March. During the night of 16 March, the activity increased significantly and there were some powerful Strombolian explosions. The event was accompanied by rapidly increasing tremor. On 16 March, the tremor fell back to a medium level and the eruptive activity came to an end.
This INGV-webcam photo from the late evening of 15 March shows the strombolian activity at the South East Crater. The vent, which is located above the large southern breach, throws the glowing pyroclastic material about 100 metres upwards. Individual bombs reach the south-eastern base of the cone (lower right half of the image):
[Un zeste de lumière ... et de chaleur ] Le 30 septembre dernier, l'imageur ultraviolet de la sonde #SolarOrbiter de l' European Space Agency - ESA a pour la première fois capturé une #éruption solaire : l'énergie stockée dans les boucles de champ magnétique a soudainement été libérée, élevant la température de la #matière environnante à plusieurs millions de degrés et générant des #radiations sur l'ensemble du spectre électromagnétique - depuis les ondes radio jusqu'aux rayons gamma.
Cette éruption de classe M (moyenne) a atteint la haute atmosphère terrestre, perturbant les communications radio au niveau des régions polaires : https://www.esa.int/ESA_Multimedia/Videos/2025/03/Solar_Orbiter_spots_a_solar_flare
