Massive Undersea Volcanism May Explain Frequent Extinctions in Triassic Period | Sci.News

A team of geologists from China and Australia has found evidence that episodic eruptions from vast marine large igneous provinces (LIPs) drove repeated lower-order extinction events in the Triassic period.

Volcanic eruptions set off a chain of events that led to Black Death in Europe

Clues contained in tree rings have identified mid-14th-century volcanic activity as the first domino to fall in a sequence that led to the devastation of the Black Death in Europe.

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/

Le #MassifCentral abrite des systèmes volcaniques tels la Chaîne des Puys et les Monts-Dore dont les dernières #éruptions datent de moins de 10 000 ans. Ils sont toujours potentiellement actifs, leur surveillance s'impose donc.

Des personnels de l' @isterre_fr, du LMV, du GET et de l'IRAP ont récemment déployé un réseau de 624 #capteurs sur une zone de 80 x 100 km² afin d'enregistrer les mouvements du sol jusqu'à 10 km de profondeur.

[Alerte, alerte ... ! ⚡] La semaine dernière, d'intenses #éruptions solaires (de classes M et X) ont donné lieu, sur Terre, à de magnifiques #aurores, ainsi qu'à d'importants #orages géomagnétiques susceptibles d'endommager les réseaux électriques, de perturber les réseaux GPS, etc.

Comment fonctionne la chaîne d'#alerte mise en place en France ? En quoi consiste un #bulletin de #météorologie spatiale ? Comment est-il transmis au grand public, aux acteurs concernés ? https://www.irap.omp.eu/2025/11/eruptions-solaires-de-novembre-2025-intense-tempete-de-particules-energetiques/

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.
