View across a landscape with relatively recent volcanism. A stream of block lava is covering the bottom part of the frame. The middle part contains a mountain slope rising from right to left, covered in volcanic ashes, giving it a distinctively smoother appearance than the lava stream in the foreground. A single conical volcano is rising over the slope in the left half of the image, exposing vibrant red and orange colors of the lapilli on its slope. The sky above is clear and bright blue. The image is composed based on the rule of thirds, with the volcano in the background as the anchor point at 1/3 from the left and from the top, and the foreground with the lava stream, the mountain slope in the middle and the sky each covering one third of the frame in vertical direction.

A new study in #Geology uncovers evidence that massive undersea volcanic eruptions—marine large igneous provinces—may have been a major, underrecognized driver of extinction throughout Earth’s history.

[6/6] L’éruption s’inscrit dans une histoire locale du risque. Depuis 1977 la lave a traversé la RN2 sept fois. Cette année-là, une coulée avait contourné l’église de Sainte-Rose, aujourd’hui appelée Notre-Dame-des-Laves, devenue un symbole du volcanisme réunionnais. #geography #volcanism #LaRéunion

Les impressionnantes images des coulées de lave du piton de la Fournaise, à La Réunion Ce vendredi 12 mars, pour la première fois en 20 ans, la lave du piton de la Fournaise, en éruption depuis un mois à La Réunion, a atteint la principale route de l’île. Aucun blessé n’est à déplorer.

[1/6] PHOTOS AFP - Le piton de la Fournaise, en éruption depuis le 13 février, a envoyé deux coulées de lave qui ont coupé la RN2 le 12 mars. Un phénomène spectaculaire qui n’avait plus été observé depuis 2007. #geography #volcanism #naturalhazards #LaRéunion

Mount Ijen in Indonesia shows unique "liquid sulphur" phenomena where volcanic vents (fumaroles) exhaling sulphur-rich gases: first channeled through pipes, then cooling to form molten red-orange sulphur that solidifies into bright yellow sulphur chunks. Local miners manually break and carry the solid sulphur in heavy loads from the crater upwards the crater rim. ©️ Picture: Thomas Hammerich

A truly massive amount of grey ash covers everything in the field of view, including a house in the foreground. All that remains visible above this eerily soft, undulating layer of grey, are the tops of trees and the peak of the house's roof.

A very similar shot of a different home, in front of the first, similarly buried under what must be at least 6 feet of ash.

A final shot of the second home in the foreground, but this time with the volcano looming in the background, apparently still emitting smoke and/or ash, though presumably at a much lesser degree that prior, as the sky has somewhat cleared relative to the other two photographs.

Found some great ref for the Ashen Plain zone I'm working on right now. This is the island La Palma (in the Canary Islands) after an eruption in 2021 (iirc).

From 27 September there is an increased likelihood of a magma intrusion and even an eruption on the Reykjanes Peninsula. The Met Office has raised the warning level. The period during which there is an increased chance may last for up to three months.

Mysterious Blobs Deep Inside Earth May Fuel Deadly Volcanic Eruptions Volcanic eruptions can destroy essential infrastructure, ground air traffic for days, wipe out entire cities, disrupt the climate for years, and even wipe out life on Earth, so it's important to know ...

New research suggests giant structures deep in Earth’s mantle may guide plumes that fuel massive eruptions. These slow-moving blobs could help explain events like the one that ended the dinosaurs.
