🌋 New study from 'Bulletin of Volcanology': ~50 km dyke intrusions, 300+ M4+ quakes and major ground deformation caused infrastructure damage, underscoring Ethiopia’s seismic–volcanic risk. Highlights the need for stronger monitoring, early-warning systems. @iavcei.bsky.social bit.ly/4roTvYu

Following the #HayliGubbi eruption, our paper on the Erta Ale dike of Jun-Jul is finally out. InSAR, optical data and seismicity showed the temporal evolution of the intrusion and the interaction of magmatic sources, including a sill inflation in Hayli Gubbi. @earth-science.bsky.social #geoscience

Our preliminary analysis of the satellite observations of the #hayligubbi #eruption is now available online: comet.nerc.ac.uk/event-respon.... Details of the eruption onset, SO2 emissions and precursory deformation.

The #HayliGubbi eruption came after a period of unrest that started in June-July 2025 with a large dike intrusion in the southern sector of the Erta Ale rift. Our InSAR study will be out soon but you can have a summary at the link below. @earth-science.bsky.social #geoscience

Hayli Gubbi - some of my photos from the Hayli Gubbi tephra sampling expedition on 24 Nov 2025 from around 10 km north of Hayli Gubbi @sorcerinsar.bsky.social @alarosa.bsky.social @wattsvolcanology.bsky.social @volckaren.bsky.social @sorcerinsar.bsky.social @alarosa.bsky.social

Activity at Hayli Gubbi began in July when there was an eruption at Erte Ale. Magma propagated 30 km south passing under Hayli Gubbi. Since then, there has been a small plume, quasi-continuous SO2 emissions and uplift. Details in @uk-comet.bsky.social event response report: tinyurl.com/y3nfdfj8

The #HayliGubbi #eruption in Afar, Ethiopia, is the first documented eruption at this poorly known volcano. Was it entirely unexpected? Difficult to say - Berhe Goitom and colleagues already reported some seismicity in 2011-2012 so perhaps there was already some geophysical unrest for a while:

Afar volcanism is known for its dyke intrusions and lava lake at Erta Ale, but here is an example of what looks like a pretty sizeable explosive eruption at a previously barely studied volcano, Hayli Gubbi 🌋🌋

Here's the GVP page of Hayli Gubbi in Ethiopia: volcano.si.edu/volcano.cfm?.... Plume from the eruption can be seen in this Aqua/MODIS image cross the Red Sea to the Arabian Peninsula. #eruption #volcano

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.

In academia, excellence appears to come with a price tag. Stresses often normalise certain behaviours such as workaholism. In this week's blog, Katherine Villavicencio writes about the effects of workaholism in academic life, and suggests us: forget the price tag! blogs.egu.eu/divisions/gd...

#MSH45 | May 19 | AM Dawn breaks over the smoldering volcano, a hulk of its former self. Yesterday morning, a 9,677-foot peak known as the "Fuji of America"—graceful, snowcapped, symmetrical. Today, a shattered crater and seared wasteland for miles north, west, and east.

M6.0 just now in Ethiopia, highest magnitude #earthquake in the swarm up until this point in time. The moment tensor only shows 12% double couple, which commonly means that the earthquake is not caused by rupture on a single flat fault plane (or it could just be poorly determined). 🌋🧪⚒️

🧪⚒️ The seismic swarm in Greece continues - and GPS stations on Santorini show that the island itself is deforming, signaling likely movement of magma deep in the crust. In our latest post, we explore a new detailed seismic catalog and come up with a possible interpretation. Read more:

Satellite imagery from @planet.com shows increased steaming in the summit caldera of Fentale volcano (Ethiopia) in the last week. Emissions appear confined to topographic lows - perhaps a meteorological effect (temperature inversion?). @davidmpyle.bsky.social @volckaren.bsky.social 🧪
