Just after midnight on 1 January 2026, a new eruption started from #Etna's eastern flank: a fissure opened at ~2100 m elevation, and a lava flow is descending through the desert-like Valle del Bove. Photos taken in the evening of 1 January from Etna's east and southeast flanks

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. vedur.is/um-vi/fretti...
A map of the southern central Reykjanes Peninsula, Iceland. A dotted bright red line shows the current active eruptive fissure. Darker red lines show guard walls meant to keep lava away from infrastructure. Darker gray shading shows all of the lava that has erupted out of the Sundhnúksgígar fissure in the 9 eruptions since December 2023; the purple shading shows the lava from previous (April 2025) eruption.
To the east, shaded in lighter gray, are the lava flows from the three Fagradalsfjall eruptions in 2021-2023.
