Hard to imagine indeed! We're doing some work on Austurhorn now so yes, happy to have a chat, will dm 👍🏼

Dr Sam Poppe @sampvolcano.bsky.social · 23d

I have trouble seeing how these felsic veins and dykes at Austurhorn #Icelqnd could have come in by pyroclastic processes and not flow of a fluid magma at 2-3km depth?
Any papers to suggest @fabianwadsworth.bsky.social @htuffen.bsky.social or others working on tuffisite veins et al?

...and then we went on to Reyðarártindur pluton, with it's roof contact showing hot interactions between granite and basalt in the roofs, even with a conduit and faults in the roof!
All described by Emma Rhodes et al in www.nature.com/articles/s41...

The second day the Tertiary Slaufrudalur pluton revealed itself magnificently (low ☁️ are regular here...), an example of a shallow granitic #magma pluton with roof contacts beautifully exposed for geologists ready to scramble upslope 🤩

The #LASI7 post-conf fieldtrip in SE #Iceland was a blast!
On day 1 Gudmundur Omar took us into the heart of #Geitafell, once a central #volcano.
We saw the gabbro intrusion that once sat at 2-3 km depth, and the most impressive sheet intrusion complex above that once fed #lava flows!

And with that, the main conference of #LASI7 is over and disappears in our foggy rearview mirrors of time! It was an honor to host all of you VIPS in #Iceland!
See you in a few years in..?

Oh yes 🤭

When you organize a conference and tell a bunch of volcanologists NOT to step on the #lava 😎👍🏼

How does lava sound when it comes to the surface of the Earth? Listen to a lava flow oozing out of its effusive vent high on the southwestern side of #Etna, 28 August 2025. That day no visits by tourists were allowed on the site, which permitted this (relatively) clean recording

You can't undo robust scientific consensus even if you tried.

It is a well-proven #fact:

Earth's #climate is changing, and that change is human-made.

To all American scientists standing up to this attempt: global #academia is with you

Visited the inspiring George Walker museum in Breiddalsvik in #Iceland last week, saw one of my most inspiring collaborators & friend @claireharnett.bsky.social win the @iavcei.bsky.social Walker award yesterday. What a boost, congrats Claire! 🤩🌋

I was followed by an amazing talk by Eleonora Rivalta on magma propagation and stress fields. What a great start to this conference!

Aaaand the #IAVCEI25 assembly has kicked off! Ready for a week of hot #volcano #science!

If you're attending, come see my plenary keynote on #magma intrusion modelling as the first one tomorrow 11:40! 🌋

Visiting the George Walker museum in Breiðdalsvík today is just such an eye-opening lesson again in field work documentation. His notebooks and hand-drawn maps are absolutely amazing in their detail and rigour 🤩🌋
