January 21, 2004, the ESA's Mars Express probe takes this image of Olympus Mons on Mars, the first high-resolution color image of the caldera of the tallest volcano 🌋 in our solar system 🌞🌗🌖🌍🌑

Went down to the mountain, I was drinking some wine Looked up in the Heaven, Lord, I saw a mighty sign Written fire across the heaven, plain as black and white 'Get prepared, there's gonna be a party tonight' Uh uh hey, Saturday night Hey uh uh, one more Saturday night youtu.be/1xGc52QkQoY?...

🙁

geologizing 🤣🤣

Desert and structural geology fieldwork are a perfect match

Pure Americana, and the perfect song for putting babies asleep (specifically the 72' Olympia theatre, Paris version, which I played more than a thousand times according to Spotify, and a few dozens more on vinyl)

Laid down last night, Lord, I could not take my rest; Laid down last night, Lord, I could not take my rest; My mind was wandering like the wild geese in the West.

A thread on this paper! 🧪⚒️ The Tintina fault is a major right-lateral fault, stretching ~1000 km across the Yukon, and having slipped a total of ~430 km in its lifetime. It's generally thought to have been inactive since the Eocene.

We've had the chance to contemplate these fascinating natural phenomena, a source of boundless wonder, but our children and their descendants won't have it... 😥 📷 @wetterkoess.bsky.social on 25.06.2025 2/

The tragic landslide in Blatten gives me the excuse to tell you the story of how we found out Ice Ages existed. It's a cool story and the most important bit is rather similar to what's happening now.

#MSH45 | The Blast Let's back up for a moment. 3.3 billion cubic yards of rock and ice crashing downslope, the landslide buries the North Fork Toutle Valley in debris up to 600 feet deep. Behind it, A turbulent cloud of ash, pumice, superheated gas, and pulverized rock.

Two features that clearly demonstrate the on-fault displacement field surrounding rupture propagation are the plant next to the wall on the left and the gate itself. Since rarely do seismic stations located so close to the fault (meters away!), these features offer unprecedented observations: 🧵⚒️🧪

Gotta love urban geology

Published!!!! The first article of my PhD and the first from the lab that I set up!! 🤩🤩 We study the dynamic effects of fault bends on earthquake ruptures by imaging shear ruptures in PMMA plates propagating through bends (double bends to be exact). www.pnas.org/doi/10.1073/... ⚒️🧪

Notice anything? 🧐 One tree-ring stands out here, with very pale latewood! 🤍 It's the famous year 536 CE, one of the coldest of the Common Era! 🥶 Early that year, a volcanic eruption caused a veil of aerosols that reduced solar radiation and cooled temperature 🌋 Subfossil larch, Aletsch Gl., CH

#FridayFold (Probably) Cretaceous carbonates tightly folded to a recumbent fold. Honestly I have no idea of what created this fold, aside from that being is an area of left-right extension and normal faulting. Really puzzling. On the Nuweiba-Taba road, Sinai peninsula

Wow!!!!!! Looks like it's the longest recorded surface rupture, surpassing the Mw 7.8 2001 Kunlun earthquake

The middle building is moving a lot more than the shorter & taller ones either side. It’s a real world example of the BOSS model simulation - how an earthquake can resonate with buildings that have matching natural frequencies, and seemingly leave others unaffected. www.LinkedIn.com/posts/mehrta...

🧵 1/3 Very excited to share here our new publication in PNAS! We reveal how drainage divides don't migrate steadily but in intermittent pulses, likely linked to paleoclimate shifts 🌍 📄 DOI: www.pnas.org/doi/10.1073/... #Geomorphology #LandscapeEvolution #Paleoclimate #OSL
