#Stromboli update — 13 Nov
A new lava overflow from the North Crater Area is sending a small flow down the upper Sciara del Fuoco. Steady spattering continues from two vents in the north, along with ongoing explosive activity from the Southern Crater Area.

Lava Lake Spattering Drives Seismic Tremor During the Geldingadalir 2021 Eruption, Iceland
The 2021 Geldingadalir eruption formed a lava lake in the crater; its lake surface rose slowly and dropped quickly during effusion episodes
As the lake level dropped, the size of the vigorously b...

For our international friends: We published our assessment of the #Kamchatka #earthquake here: www.gfz.de/en/press/new... -- It was one the strongest earthquakes ever recorded with instruments. The ground near Berlin, Germany, moved up 2 and down 4 millimetres, so a 6-mm movement.

Watch the seismic waves from the magnitude 8.8 earthquake off the coast of Russia sweep beneath seismic stations in North America.
By the time the waves reached North America, they are far too small to be felt by people, but can still be detected by seismic instruments. 🧪

Veðurstofan has now published a map of the current fissure eruption on the Reykjanes Peninsula.
The active fissure is marked in red, and is about 700 meters long. The little topographic high just northeast of the end is the cone from the August-September 2024 eruption.

A new volcanic #eruption has just begun moments ago on Iceland's Reykjanes Peninsula (far left side of video). This one so far appears to be well north of the town of Grindavik, along the north end of the dike that has fed all previous eruptions.
