Not one, but TWO paroxysmal eruptive episodes at #Etna's Northeast Crater on 27 December 2025, AND minor activity at the Voragine crater. Though the Northeast Crater has frequently shown minor activity in recent decades, its last paroxysmal episode was on 27-28 March 1998.

USGS Volcanoes🌋
USGS Volcanoes🌋@USGSVolcanoes·
Episode 37 of the ongoing Halemaʻumaʻu eruption began at 2:30 p.m. HST on November 25 and is ongoing. Sustained lava fountains at the summit of Kīlauea are about approximately 400 feet (120 meters) in height. Winds are light from the north-northeast and will take most tephra and gas to the south-southwest.

❌Sin ciencia, no hay futuro "Tenemos un PIB mínimo dedicado a la ciencia" "Queremos conseguir trabajos estables" Ya no es que se reconozca a los científicos, es que con precariedad e inseguridad laboral se pueden ver obligados a abandonar los proyectos o irse a otros países

📗 Este 26 y 27 de noviembre huelga de universidades contra Ayuso y el gobierno del PP. Quieren asfixiar la universidad pública a golpe de recortes, amordazar la movilización y adoctrinar mediante contenidos decididos por los empresarios. #SalvemosLaPública #Huelga2627N.

🟥 ⛏️ Zumaia nestled along the dramatic Basque Coast in northern Spain, is renowned for its iconic flysch formations, a mesmerizing geological feature that transforms its beaches into a natural timeline etched in stone. ❤️ 🔁 #ZumaiaFlysch #BasqueCoastGeology 🎞 @Antafromabove ▶️ These "beach rock" structures, often referred to as the Klintzarri flysch, consist of steeply inclined, vertically exposed layers of sedimentary rock that stretch for about 10 kilometers along the coastline. The formations are a rhythmic stack of alternating hard and soft strata: durable sandstone and limestone layers (resistant to erosion, forming prominent ridges) interbedded with softer shale, clay, and marl (which erode more easily, creating dramatic overhangs and wave-cut platforms). This creates a distinctive "millefeuille" or layered cake appearance, with individual beds as thin as a few centimeters to several meters thick. The rocks span over 100 million years of Earth's history, from the Cretaceous to the Eocene periods, and are so well-preserved that they reveal fossils, ancient seabeds, and even evidence of the dinosaur extinction event (the K-Pg boundary layer is visible here, marked by iridium-rich sediments from the Chicxulub impact). As part of the UNESCO Global Geopark of the Basque Coast, these formations rise dramatically from the Atlantic waves, offering a rare window into deep-sea sedimentation processes right at sea level. ▶️ The flysch in Zumaia originated in a deep marine foreland basin during the Late Cretaceous to Paleogene epochs (roughly 70–50 million years ago), as the Iberian tectonic plate collided with the Eurasian plate in a subduction zone setting. This convergence compressed sediments scraped from the ocean floor, leading to rapid deposition of alternating turbidite layers, underwater avalanches of sand, silt, and mud triggered by earthquakes and underwater landslides. These turbidity currents deposited graded beds (coarser grains at the base grading to finer ones upward) in a subsiding basin, building up thousands of meters of sediment over time. Tectonic uplift from ongoing plate compression later exposed these once-horizontal layers vertically along fault lines. Coastal erosion by the relentless Bay of Biscay waves has since sculpted the softer layers away, accentuating the hard bands and carving out the iconic cliffs and beaches we see today. This dynamic interplay of deposition, tectonics, and erosion continues to shape the landscape, with the sea slowly "unzipping" the geological record.
