Incredible aerosol reaching Val Veny bottom at 3 pm today! ❄️

The avalanche is coming from the slope below Noire de Peuterey (3773 m) and what you see here is the blast of the avalanche (=no danger) reaching the Val Veny (La Zerotta lift at 1520 m) near Courmayeur! 💨

The Morcles Nappe by Héli Badoux Since the turn of the 19th and 20th centuries, Swiss geologists have been renowned for their cross-sections which spectacularly reveal the structure of the Helvetic nappes. Among t

New post 👇 on my #Tectoldies blog. It's about beautiful cross-sections of the Morcles Helvetic nappe in the Swiss Alps 🏔️

First in a series I plan to share about those amazing Swiss #tectonic cross-sections. Stay tuned. ⚒️

All these point in one direction: the climate is changing, and the rapid changes started after the steam engine was invented and society started using fossil fuels to generate heat and power on an industrial scale.

Perhaps we ought to think about curtailing our use of fossil fuels?

Just an idea.

US applications for prestigious European research grants surge Rush for funds to relocate laboratories to Europe is latest sign of a US brain drain.

US applications for prestigious European research grants surge 👇

"…but it is not clear whether Europe has the funds to absorb these extra researchers without increasing competition for existing staff."
(without change in total budget and success rate it will not)

Agree 💯

LLMs are very bad with tectonic faults and earthquakes. Just to test if it might be "useful" by any chance, I tested this several times, and it's consistently disastrous.

Each time, suggested sources (academic papers) were very limited, repetitive, and not at all the important papers on the subject. This could be due to the database not using paywalled papers... but not only that, because important open-source articles weren't cited. In short, another black box 2/2 ⚒️

Open-source AI tool beats giant LLMs in literature reviews — and gets citations right Researchers can deploy the cheap and transparent model on their own computer system.

A new fully open-source #AI LM model claims to be more efficient for scientific literature search and synthesis.

I tested their online portal with a few questions on tectonics and/or earthquakes and, hmm, it worked very badly… 1/2 ⚒️

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.
