New paper argues history, not mantle plume, powers Yellowstone

A now-vanished plate under North America may open the crust below Yellowstone.

As part of my project, I challenged myself to spot natural areas beyond the mainland United States, and even beyond Hawai'i and focused on various overseas territories of the country. One of those I spotted were the Northern Mariana Islands, and spotted the Northern and Southern Pagan Volcanoes.
These are two stratovolcanoes connected by a narrow isthmus. Both volcanoes are exposed calderas due to previous eruptions, which are caused by the subduction of the Pacific plate under the Mariana and Philippine plates.

Much like Hawaii Volcanoes National Park, this would-be national park would protect active lava flows (evident by North Pagan's basalt fields) and various endemic life like the Mariana fruit bat, the Myzomela rubratra ssp. asuncionis, and so on. Further, today, the island is semi-inhabited by a non-permanent population of Carolinian and Chamorro people.

One of the main environmental issues facing this remote area include invasive species such as cattle, Sambar deer, goats, pigs, Antigonon leptopus (love vines), Spathodea campanulata (African Tulip trees), and plans by the United States Navy to transform the island into a Range and Testing area under the belief it's permanently uninhabited.

Das Lavagestein auf Methana erzählt vom Feuer, das hier vor rund 2.300 Jahren austrat. Die porösen Blöcke erkalteten zu bizarren Formen. Manche Flächen glänzen glasartig, andere zerfallen zu bröseligem Staub.

Some picture from the geological more active areas of Iceland. Due Iceland is famous for it's pool of warm water where you can actually take a bath in it, it is not recommended to take a bath in any of these pools here.
Does anyone know the Star Trek TNG-episode "Skin of Evil"?

The #MassifCentral is home to volcanic systems such as the Chaîne des Puys and the Monts-Dore, whose last #eruptions date back less than 10,000 years. They are still potentially active. Monitoring them is therefore essential.

For this reason, staff from @isterre_fr, the LMV, the GET Laboratory, and IRAP, recently deployed a network of 624 sensors over an area of 80 x 100 km². This device aims to record ground movements up to a depth of 10 km : https://www.irap.omp.eu/en/2025/11/maciv-nodes-an-exceptional-seismological-network-on-the-volcanoes-of-the-massif-central/

The #Volcanic Isles . A brief history of volcanism across The British Isles.

Quite pleased with how this one turned out.

Location of volcanoes taken from wikipedia (spotted a mistake and got to make an edit to wikipedia in the process); fault lines from the #BGS 625k bedrock dataset and the IE GSI 500k Bedrock Geology for Ireland. Font: League-Spartan by the League of Moveable Type.

#requests, #pandas and #geopandas for scraping and wrangling.#scipy for making the proximity surface (that's the colour scheme), #matplotlib for plotting. With all labeling done manually in #inkscape.

EDIT: I've been kindly and helpfully informed that (a) Ben Nevis' age is closer to 399 Ma; (b) some are missing; (c) others perhaps shouldn't be there; (d) it's complicated. So, maybe don't use this map to make any strategic decisions.

🌋 Io: A volcanic world in Jupiter’s grasp

Sculpted by gravity and painted in sulfur, Io is a volcanic world of mountains and storms; its heart beats with tidal fire. It is the most active body in our Solar System, reshaped endlessly by eruptions and Jupiter’s pull.

✍️ Explore the full article here: https://TPC8.short.gy/euoVEw7N

Every eruption tells a story of fire, gravity, and the science that reshapes worlds.

Vista desde Kagoshima. Tras 35 años de descanso, el volcán Sakurajima se despertó el 12 de enero de 1914 con la erupción Taisho, la de mayor intensidad y magnitud de Japón en el siglo XX. Su actividad, que duró hasta abril, absorbió pequeñas islas cercanas y unió a su propia isla con la península de Ōsumi. #vulcanismo #volcanism
