🌋Would you like to see the 2021 #Fagradalsfjall eruption from above? Christopher W. Hamilton, Brett Carr and Joana Ruth Charlotte Voigt present georeferenced drone imagery capturing lava flows and vent locations from surveys by the University of Arizona Lunar and Planetary Laboratory. 🔥A powerful aerial view of a volcano in action.

La rubrique « L’éruption » revient sur la catastrophe du Nevado del Ruiz, qui frappa la Colombie en 1985. Une éruption pourtant mineure, mais qui fit fondre le glacier sommital du volcan, générant des lahars (coulées de boue volcaniques) qui ensevelirent plusieurs villes. Avec environ 25 000 morts, il s’agit de la deuxième éruption la plus meurtrière du xxᵉ siècle. Nous revenons sur les facteurs, notamment humains, ayant causé ce drame largement évitable. ⬇️

Après deux recensions d’ouvrages récemment parus, quelques pages sont consacrées à l’actualité éruptive du premier trimestre 2026. On revient notamment sur l’éruption du Piton de la Fournaise, mais aussi sur des épisodes éruptifs au Kīlauea (Hawaï), au Manaro Voui (Vanuatu), au Nyamulagira (république démocratique du Congo) et à El Chichon (Mexique). Sans oublier les explosions spectaculaires de deux volcans de boue. ⬇️

💁🏻‍♀️ ICYMI: 🌋🌊 Filmmaker Devon Massyn documents the raw #physics of a phreatomagmatic #eruption at the #SolomonIslands' #Kavachi submarine #volcano.

When seawater makes contact with 1,200ºC (2,190°F) basaltic #lava, it flashes into steam and expands 1,600 times its original volume. This creates violent #underwater explosions in an #ecosystem that surprisingly supports hammerhead and silky #sharks.

We were getting pelted with large chunks of tephra! This is why they close the park, these chunks can cause serious lacerations. Akahele!

Later in the day yesterday when it was more safe, we packed up Indy and brought him to Volcano House to get a different angle of the eruption. He was very popular with the tourists!
