I'm senior researcher at (Centre National de la Recherche Scientifique) and (Institut de Physique du Globe de Paris).

Working on , and sometimes processes, related and risks, science communication…

I'm executive editor at TEKTONIKA (a DOA journal not yet on Mastodon), and advocate of , free

Just moving from Twitter to Mastodon, and learning how to use it. Will keep the two accounts alive, at least for some time…

The Eastern coast of Taiwan is prone to big as this map from Tang and collaborators shows. Main shallow crustal active faults are the Central Range Fault (W-dipping, earthquakes and ruptured zones in red and orange) and the Longitudinal Valley Fault (E-dipping, in blue) 5/n

Two magnitude 6+ event happened in 2018 and 2019 in the very same region than the 3 Februaryb 2024 Mw7.4. The 2018 Mw6.4 had a complex (strike-slip + reverse, several fault segments) shallow crustal rupture.

This E-W section at Hualien latitude only shows a 2D view of the complex 3D structure. If the ~20-40km hypocentral depth of the Mw7.4 is true*, it's difficult to figure out which fault ruptured. Could be one not reaching upper crustal levels. Just hypotheses.

Section from Lallemand 2014,

* Saying "If the ~20-40km depth of the rupture is true" is a big IF as the Taiwan seismic center puts epicenter of the main shock at 15km only. Needs further studies.

Source region of Mw7.4 of 6 Feb. has a complicated 3D lithospheric structure: interaction between the Ryuku subduction and accretionary wedge, the accreted Luzon arc (now forming the coastal range), the Philippines plate, and the Taiwan orogenic prism (central range and foothills).

And this: "China’s addiction to building new coal-fired power plants is becoming increasingly entrenched…" in The Guardian

Also this: "The United States is poised to extract more oil and gas than ever before in 2023, a year that is certain to be the hottest ever recorded, providing a daunting backdrop to crucial United Nations climate talks" in The Guardian

BBC writes: The United Arab Emirates planned to use its role as the host of UN talks as an opportunity to strike oil and gas deals. 😒

Ding et al. simulate various scenarios to analyze a backward rupture branching during the 2023 Kahramanmaraş earthquake, and show it can occur by both direct and indirect triggering depending on the fault's initial stress and friction conditions

On BBC, Macron calls for cease fire in . He calls on Israel to stop killing Gaza's civilians, women and babies. Listen to excerpts of BBC interview (linked).

That's strong and valuable words, but the problem is that Macron doesn't have the same words in French and on French media…

The dataset, linked to the article "Upper-plate Shortening and Mountain-building in the Context of Mantle-driven Oceanic Subduction", includes videos and photographs depicting the evolution in top and lateral views of the 5 analogue experiments.

In our new paper, Habel et al. 2023, we use analogue models to discuss the effect of mantle flow on upper-plate shortening, and building in Andean margin context. The paradigmatic type being the in front of the Nazca-South America plate boundary.

Proud and happy that it is published in TEKTONIKA DOAJ (@wearetektonika )


Do you know that #Tektonika #DOAJ will consider publishing Field Guide articles ?

Shortly: "Fieldwork Guides should aim to offer valuable insights into pivotal structural geology and tectonic concepts through the provision of concise, insightful accounts of key geological localities. Fieldwork Guides should ensure accessibility and utility for a wide audience, from students to seasoned researchers."

Don't hesitate to contact our editors to get more infos, help, and discuss possible submission

Today's reading 👇, some historical papers, with the idea to enrich our teaching in the field next year about the Sparta 464BC

Exploring the Origin of Geoid Low and Topography High in West Antarctica: Insights from Density Anomalies and Mantle Convection Models

Steinberger et al. have studied the geoid low and dynamic topography in the Ross sea area and West Antarctica, and modeled the mantle structure and its reduced viscosity.
