👇 A great collaboration with @gernon.bsky.social, Thea Hincks, Martin Palmer (all @unisouthampton.bsky.social), Chris Spencer (Queen’s University), @wattsvolcanology.bsky.social (Swansea University) and Anne Glerum (@gfz.bsky.social) 👇
Many oceanic islands far from active plate tectonic boundaries contain materials clearly originating from continents, even though they are located in the middle of an oceanic plate. Where do the continental remnants come from? @sasbrune.bsky.social, and lead author Thomas Gernon from 1/5

An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.
