En soutien à nos collègues scientifiques US, et pour défendre la #science comme bien commun, partout dans le monde, des actions en cours d'organisation en France. #standupforscience2025 ⚒️ 🧪 Être informés: @standupforscifr.bsky.social @sufs-paris-rp.bsky.social (Paris + IDF) standupforscience.fr

Excellent parody by Le Gorafi (FR equivalent of The Onion): Adolf Hitler, claims to have discovered with “astonishment” and “horror” that the #Wikipedia encyclopedia considered him a prominent member of the European #fascist and national-socialist (nazi) movement. www.legorafi.fr/2025/02/26/a...

Je partage ici le message d'un collègue argentin a qui je demandais des news. Glaçant 😱! La Méthode Milei (bel euphémisme gerbant) démantèle éducation&recherche, cible les savoirs qui comme aux US, gênent politiquement: climat&écologie, justice env. Le fascisme s'installe. Sommes-ns a l'abri en 🇪🇺?

Pour être tenu.e au courant par mail des actions organisées à Paris et en région parisienne pour la journée Stand Up for Science : framagroupes.org/sympa/info/s...

Scientists are now organizing events, called Stand Up for Science, on 7 March in Washington, D.C., and state capitals. So far, they have attracted more than 100 volunteers from some 30 states who are hoping to rally support for research as a public good. scim.ag/4328LAD

Le 7 mars, mobilisons-nous pour les sciences ! 🔬✊ En écho à Stand Up For Science (@standupforscience.bsky.social) et face aux menaces contre les institutions scientifiques, des actions auront lieu dans chaque ville universitaire de France. Infos & inscriptions 👉 standupforscience.fr

On March 7, let's stand up for science! 🔬✊ In solidarity with Stand Up For Science US (@standupforscience.bsky.social) and in response to threats against scientific institutions, actions will take place in every university city in France. Info & registration 👉 standupforscience.fr

Oh shit, this is NOT my president... (I mean the one to the left, not the far-right orange 🤡)

Brilliant protest. Yosemite National Park workers hung an upside-down American flag — traditionally a symbol of distress or a national threat — thousands of feet off the ground on the side of El Capitan.

I can't be the only one who thinks these people are doing the Nazi salute in this AfD poster.

We're back to the occasional M5-ish #earthquake, but fewer M3-4 compared to before, with no end in sight for the seismic sequence NE of Santorini, Greece. Once again, the data was downloaded from GEIN this morning. ⚒🧪

This morning, the US National Science Foundation fired 168 employees, approximately 10% of its workforce, for no cause other than they were the agency's most recent hires. 🧪 Co-workers are leaving supportive messages before they have to clear out of the building at 5 p.m. Sent to me by a source ⬇️

I want to see the American Geophysical Union (AGU) continue its awesome work on justice, equity, diversity, and inclusion. This thread is a call to AGU and AGU members. 1/

#volcan #volcano #Fentale La partie est du plancher de la caldera a subi une très forte subsidence ces derniers jours (images des 11 et 16/02)/The eastern part of the caldera had a strong subsidence in the last days (picture of 11&16 /02)

Magnitude 6 #earthquake in #Ethiopia. Largest event of ongoing swarm. Epicenter close to Fentale #volcano. Depending on institutes ≠ moment tensor solutions, ex. below. USGS non-double couple solution (right) could perhaps mean caldera or magmatic chamber collapse + ring faulting (just hypothesis).

Moment magnitudes and corner frequencies calculated for 437 events from the Santorini crisis (Ml>3.5, Jan 24 - Feb 13) using SourceSpec. Big thanks to the EIDA node of the National Observatory of Athens for keeping their services online during this critical period. sourcespec.seismicsource.org

Yesterday we have had an excellent first day of #LITHODEF25 workshop on #tectonics and mechanics of the #lithosphere. ⚒️ Full @ipgp.bsky.social amphitheater, great talks and discussions. Now ready for second day 🙂

Start of the #LITHODEF25 workshop at the Académie des Sciences ⚒️

At Paris AI summit, JD Vance has said: "Partnering with [authoritarian regimes] is like shackling your nation to an authoritarian master who seeks to infiltrate, establish itself, and seize control of your information infrastructure." 🤡 As reported by @lemonde.fr www.lemonde.fr/economie/art...

You too, post your fave card from the #Gulf of #Mexico. Tú también, publica tu mapa favorita del Golfo de México. 👇 El Golfo Mexicano y su gran pez o ballena. Tomado de un mapa que data de 1594. ⚒️ 🧪 Source: gallica.bnf.fr/ark:/12148/b...

The main DEI page from @agu.org has been modified to take diversity out of the title. Glad to see it's not deleted entirely, but hey AGU, we're watching what you do and remembering the big game you once talked about supporting your diverse membership. Today vs. January

Hi Seismo-Bluesky! I decided to test a pipeline with SeisBench, PyOcto, NonLinLoc, and HypoDD on the Santorini sequence. The level of activity (>4,500 events) is truly stunning! There are repeated bursts migrating backwards and forwards, spreading outwards from a narrow, almost linear channel.

Only 2 days left before the LITHODEF25 workshop @ipgp.bsky.social ⚒️ 🧪 Infos and program lithodef25.sciencesconf.org We have reached the maximum capacity of our rooms, so no more registrations. Sorry. We plan to record the talks and then broadcast them later via IPGP YouTube channel.

Hey, #Americans, why aren't there huge demonstrations on your streets with dozens of thousands of very angry people? The #coup which is happening to you is extremely bad for you, but also for the whole world.

Large magnitude Mw7.6 #earthquake along Cayman Trough at NW boundary of #Caribbean plate. Mechanism is sinistral strike-slip. This fault system already ruptured in Jan 2020 more to NE (on Oriente Fault) and May 2009 to the SW. ⚒️ 🧪 Source Geoscope @ipgp.bsky.social : geoscope.ipgp.fr/index.php/en...

There are innumerable things that concern me about the goings on in Washington right now, but this one has just risen to the top of the list. Geohazards are not a domestic consideration. Many (tsunami, anyone?) are by definition global hazards.
