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.

We've added two new, updated maps to our post, tracking the latest seismic data in Iceland. Here's one; head to our blog to find the other one: earthquakeinsights.substack.com/p/volcanic-e...
The likelihood of a eruption in the coming days is "significant": en.vedur.is/about-imo/ne...
