#Volcanic #eruption of 536: from #Avars to #AngloSaxons to #Teotihuacan to rise of #Islam https://www.youtube.com/watch?v=AYAsw1o7AMs Not to mention #Darwin, #volcanoes and #evolution my take here https://nkozphoto.com/index.php/2025/09/24/volcanoes-climate-change-and-darwins-legacy-in-chile/ #science #climate #history #chile

The study indicates that ash from the #Nishinoshima #eruptions was transported by wind and #ocean currents to the waters around #Mukojima, serving as a nutrient source for #phytoplankton growth in that area.
The findings suggest that volcanic ash can enhance the productivity of #marine waters even at considerable distances from the #volcanic site.

Researchers Discover Five New #HydrothermalVents in Pacific Ocean https://www.sci.news/othersciences/geoscience/east-pacific-rise-hydrothermal-vents-12799.html

"#Hydrothermal vents are rich in chemicals that supply energy to #animal life, fueling rich and productive #ecosystems. The new sites... are located on the #EastPacificRise near 10°N latitude, a part of the globe-spanning mid-ocean ridge #volcanic mountain chain, where two #TectonicPlates are splitting apart at a rate of about 11 cm per year."

RT by @CopernicusEU: The latest #eruption in #Iceland has produced the largest #volcanic SO₂ cloud measured to date in the 2023-24 #Reykjanes Fires, consistent with reports that it is the most intense episode so far.
Data: @CopernicusEU #Sentinel5P #TROPOMI.

Scientists Discover New Ecosystem Underneath #Hydrothermal Vents https://schmidtocean.org/scientists-discover-new-ecosystem-underneath-hydrothermal-vents/

"New #ecosystem has been discovered in #volcanic cavities beneath #HydrothermalVents at a well-studied #undersea #volcano on the #EastPacificRise off #CentralAmerica. The landmark 30-day expedition aboard #ResearchVessel Falkor (too) was led by Dr. Monika Bright... Using a #robot, they overturned chunks of volcanic crust, discovering #cave systems teeming with #worms, #snails, and #chemosynthetic #bacteria"
