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…

New published paper by TEKTONIKA 👇🏽 @wearetektonika
#DOAJ free to read !

In this paper, Júlia Gómez-Romeu et al. use a thermo-mechanical model to investigate the behaviour of inverted magma-rich versus magma-poor rifted margins during early orogenesis.

Seismica is announcing a special journal issue on the 2023 Kahramanmaras, Türkiye earthquake sequence, with papers free-to-publish and free-to-read.

#DiamondOpenAccess #seismology #EarthquakeScience

Precise, NLL-SSST-coherence earthquake relocations for the 2023 Mw7.8 and Mw7.6, Kahramanmaraş-Gaziantep, Turkey earthquake sequence (including 2020 Mw 6.8 Elazığ, Turkey sequence). Seismic arrival data from Details & catalog available at:

At Tektonika, we are recruiting volunteers to join our technical team (as copyeditors and typesetters). For more information, and to register your interest, head over to

Deadline is March 20th

#DOAJ #openscience

After big #earthquake, explaining geological processes can help affected community & general public to understand what happened.

Open access is crucial.

DOA journals – Free to publish, Free to read – should be best targets for scientific papers on the 6 Feb 2023 #kahramanmaras #earthquakes (Turkey).

At TEKTONIKA, we invite paper dealing with seismotectonic & geological aspects: e.g., coseismic deformation and modelling, rupture description, field observations, context, etc…


As TEKTONIKA publish a 2nd paper, some infos and reminders:

• We opened for submission end of May 2022.

• Time between submission and publication were 7 and 7.6 months for our 2 first papers.

• Link to first issue (in progress)

• Send us your manuscripts ! They will be free to publish, free to read, free to share !

And don't hesitate to contact us if you want to help. Several technical, communication, etc… tasks need to be filled.

🆕 We have published our second paper ! 🎉

Courte video IPGP - Université Paris Cité, dans laquelle j'explique le contexte des du 6 Février en Turquie.

"3 questions à Robin Lacassin sur les séismes du 6 février 2023 en Turquie" :

Updated map of #Turkey #earthquake sequence, with historical #seismicity. The events after the M7.6 (light purple) now more clearly delineate the entire #rupture & merge to the East with the events after the M7.8 (dark purple). Quakes have continued on the M7.8 EAF segment as well.

I try to post in French and English about the Turkish , here and also on the bird site (where I still reach much more people interested in natural hazards). Also responding to French media…

Not enough time to explain everything in detail though… 😕 Don't hesitate to ask, I'll try to answer whenever possible.

Thoughts for the many victims and injured in Turkey and Syria ❤️

Deux failles décrochantes du système Est Anatolien (EAF) ont rompu aujourd'hui dans le SE de la .

Le premier , de magnitude Mw7.8 à 8, a cassé plusieurs segments du “EAF main strand” sur une longueur de 150 à 300km. Le second, également de forte magnitude, Mw7.5 à 7.7, s'est produit plus au nord sur la faille de Sürgü-Çartak (EAF northern strand). En carte, les deux failles rompues, toutes deux sénestres, sont marquées par l'alignement de leurs répliques.

De très nombreuses répliques ont suivi les deux chocs principaux, mais le second puissant séisme est plutôt une rupture déclenchée sur une faille adjacente. Il ne peut pas être qualifié de réplique au sens strict.

Ces évènements, fortes répliques et séisme déclenché, nous rappellent qu'il faut rester très vigilant pendant les jours/semaines/mois qui suivent un très fort séisme.

Two faults of the East Anatolian Fault (EAF) system ruptured today. First, a Mw7.8 on EAF main strand probably breaking several segments. Second a Mw7.5 to 7.7 on the Sürgü-Çartak Fault (EAF N strand). Both ruptures are outlined by their aftershocks (circles on map), and both are left-lateral.

There are many aftershocks following the two big earthquakes, but the second rupture is rather a triggered earthquake on an adjacent fault belonging to the EAF system.

This reminds us to be wary of possible strong aftershocks or triggered ruptures in the following days-weeks after a big earthquake.

Strong destructive in SE Turkey / N Syria, magnitude Mw~7.8.

Mechanism compatible with left-lateral strike-slip on the southern part of East Anatolian Fault system. Aftershock zone extends for ~250km along that fault system. Complex source time function may suggest rupture on several fault branches. The left-lateral East Anatolian Fault system bounds the Anatolian tectonic microplate to the east.
