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).

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)
Leaving Texas, fourth day of July,
Sun so hot, the clouds so low, the eagles filled the sky.
Catch the Detroit Lightning out of Sante Fe,
The Great Northern out of Cheyenne, from sea to shining sea.

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.

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.

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:

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 🌋

(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.

Wow!!!!!! Looks like it's the longest recorded surface rupture, surpassing the Mw 7.8 2001 Kunlun earthquake
Update: Preliminary coseismic displacements of 2025 Myanmar earthquake from @CopernicusEU @ESA #Sentinel2 images by using #CosiCorr, processed by @NTU_TW GEOG
#Copernicus
1. Rupture propagated from N to S
2. Max. offset >4m
3. Rupture length ~500km
