It's about time I announced a project that I've been working on in the last year... I wrote a book!

'Volcanoes: 10 things you should know' published by @orionbooks.bsky.social Seven Dials will be out in September. It's available to pre-order now. Links: linktr.ee/volcanologist
A graphic of a book. The cover is a deep red and had a good line illustration of an erupting volcano.

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

More Greenland photos, featuring some geology. Scoresbysund has some fantastic exposures of columnar basalts, which are ~55 million years old (young for Greenland rocks!) related to flood basalts when the Atlantic was opening up. Fantastical shapes and fall tundra colors

What's the 2025 equivalent to a Walkman?

Mini-volcanologist is 8 and loves music and dancing to music. She has an Echo Dot at home, but it's reliant on Kids Radio. We want something portable she can curate and play her own music on. Not a phone.

At this age I was attached to my Walkman. Recs?

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

We think there was a small eruption there in July/August (at least a small plume) and some ongoing activity there since (including continued uplift). I suspect all linked to recent activity along dyke from Erta Ale (See COMET reports on July/August activity at comet.nerc.ac.uk/event-respon...).

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:

An eruption from the #HayliGubbi volcano in #Ethiopia resulted in a large ash cloud, visible here from space. 🌋

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.

I thought either lightening or literally the eruption sound of material being rejected from the vent. I've heard recordings of that before.

Though, I would imagine a PDC to make noise, like an avalanche. The Kraffts video always super surprised me.

Thev sound in this video is fascinating. You can hear what I think is background rain and pumice fall. But the roaring... Is that from the eruption or from the PDC? In contrast to that PDC video from the Kraffts where the the current is silent.
