In this paper, we quantify the tectonic deformation and document paleoearthquake activity in the Northern Andes of Ecuador egusphere.copernicus.org/preprints/20...

In this paper, we evaluate the long-term slip rate of the fault that caused the deadly M6.4 Petrinja, Croatia, #earthquake in 2020 tektonika.online/index.php/ho... Congratulations Maxime!

Last week trenching the northern Alpine Fault at Blue Grey River w/ @stef-eq-geology.bsky.social and @jameslagreca.bsky.social and friends looking for paleoearthquakes. Many sandfly enemies too

Phalasarna was a Hellinistic port that was massively uplifted (~8 m) during the well-known 365 AD M>8 Crete #earthquake. Perched notches are also visible in the area. link.springer.com/chapter/10.1...

NASA JPL ARIA project analysis of data from Copernicus Sentinel-2 optical and Sentinel-1 radar images measured the slip on the Sagaing Fault in Myanmar. Quick preliminary map. More details later. Fault ruptured about 500 km (300 miles) in the magnitude 7.7 […] [Original post on mastodon.social]

Remote surface rupture observations for the M7.7 2025 Myanmar earthquake - soft rollout! doi.org/10.5066/P1RY... Simple fault trace and slip distribution from pixel tracking, high-res from available imagery. Watch for updates! ⚒️ USGS and collaborators effort led by @nadinegrr.bsky.social 🙏

This matches very well with traces of the surface rupture visible a few km to the north on the high resolution Planet SkySat images (thank you Planet!). The offset road is the northernmost point on the overview, and I measured about 4.5 m of offset there.

Analysis of the 2024-10-05 M 4.5 Iran #earthquake signal revealed that it was a natural event, not a nuclear test seismica.library.mcgill.ca/article/view...

Here are the Proceedings of the marvellous INQUA PATA Days in Chile, last october (2024), on Active #Tectonics and #Paleoseismology : libros.uchile.cl/1446 Thanks again to the organizing team !

10 years ago I thought I wasn't smart enough to study #geology, but some colleagues convinced me to try anyway. Today I just published my 2nd paper, which explores how fault ruptures can alter river behaviour and flood hazard. Check it out here! www.sciencedirect.com/science/arti...

Le cyclone #Chido, classé en catégorie 4, a dévasté l’archipel de Mayotte le 14 décembre 2024, avec des vents soufflants à plus de 220 km/h. C’est le cyclone le plus important depuis 1934. Le dernier cyclone majeur datait de 1984. Un 🧵 [1/24] 👇

Brillant PhD thesis defense yesterday, after 3 years on such a tough topic: paleoseismology of a slow active fault in SE France. That was such a great experience to supervise your work Nicolas. Congratulations Dr Cathelin 🍾👍

Last weekend we had an amazing campaign on the Alpine-Wairau (Big) Bend of the Alpine Fault, Glenroy River. Thanks to @jameslagreca.bsky.social Liv & Alex for doing the mahi. We located THE one and only Alpine Fault outcrop in the valley and also sampled the Glenroy rock avalanche. Still buzzing!

Quick recap from todays recon of yesterdays M5.8 earthquake. Bottom line: no surface rupture observed after several transects across aftershock pattern.  Lack of any surface cracking in epicentral area. Minor bank failures, lateral spread, and liquefaction features along Walker river.

Impact of deglaciation on fault slip. I could only read the abstract right now, but this paper seems quite interesting. pubs.geoscienceworld.org/gsa/geology/...

First update of slip model for M 7.0 - 2024 Offshore Cape Mendocino, California Earthquake. Using closest stations (dist < 200 km). Still no selection of fault plane (both nodal planes shown). SLIPNEAR method.

During his Master, Nicolas estimated the uplift rate around the Cévennes fault system (responsible for the 2019 M5 Le Teil #earthquake in SE France). He used 3He cosmogenic dating of fluvial terraces including basalt pebbles. journals.openedition.org/quaternaire/...

New results on the deep structure of the Cévennes #fault system, responsible for the 2019 M5 le Teil surface-rupturing #earthquake in SE France. Congrats (young) Dr Thomasset!!! www.bsgf.fr/articles/bsg...

This outcrop with active Andean thrust deserved two US legends of #earthquake #geology. Could you recognize them?

Another PATA Day in NW Argentina 🇦🇷. Gracias to King Carlito Costa for the tour of the Las Peñas thrust. We're based in Mendoza for 2 nights. Having a quiet one with mates @faultcreeper.bsky.social and @stef-eq-geology.bsky.social

A post-PATA field trip across the Andes! OK sure. How do I choose 4 of the best photos?
