@ChemBob Agree about "the biggest reservoirs of money". We need a drastic structural change (revolution?).
Keep in mind that a dude spent 44 billion $ to buy and likely destroy a social network. Same dude sent an empty car to the stars…
Well, the twittosphere and matodosphere marvel at the launch of #Artemis #lunar rocket by #NASA…
That's fine. But is it really a priority for humanity in the face of much greater and more vital challenges like #climate and #biodiversity crises and the urgent need to mitigate and adapt ? I doubt.
Don't hesitate to comment.

Je découvre le hashtag #MastoArt grâce à @HygieneMentale... Merci ! 🤩
Ma contribution du jour : Guépard en pleine course, #illustration que j'ai réalisée pour le livre documentaire jeunesse "#Félins", écrit par le naturaliste Marc Giraud.
Few months ago, together with @RaphaelGrandin and J.M. Lalande from MeteoFrance, I participated as a scientific advisor to the making of this amazing scientific illustration 👇 #scicom #sciart
It summarizes scientific observations on the Hunga #Tonga #volcano explosion, associated global #tsunami and atmospheric waves.
French newspaper Le Monde published these 2 pages in September 2022. Great work by the journalist and the graphic designer, Vahé Ter Minassian and Audrey Lagadec.
DM if you would like a higher resolution PDF 😉
This most recent #Fiji M7.0 earthquake is not as close to the bottom of the local #intraslab seismicity as the previous deep #earthquakes a few days ago.
(note that the focal #mechanisms are projected onto the vertical cross section)
The #Tonga/#Fiji #earthquake sequence is not done yet! Another very deep M7.0 #quake today, 100s of km North of the previous deep events in the region a few days ago.
A significant sequence of #earthquakes occurred this week in the #Tonga-Fiji #subduction zone. First several events at great depths (600+ km) within the subducted slab, then today a very different type of event: a deep compressional outer rise earthquake. I have plotted these four earthquakes on this map in the context of historical #seismicity.
Since there was interest, I have set up a Google Form/Sheet for Earth Scientists on Mastodon.

High resolution (2 meters) Pleiades DEM allowed quantitative analysis of the flights of marine terraces marking Kythira island coast.
Thanks to CNES Isis program which provided us with the Pleiades imagery.

I'm last author of this recently published paper on the Quaternary #tectonics and uplift of the Kythira island (#Aegean sea and Hellenic Arc) by Gino De Gelder et al., in AGU Tectonics.

Working on #geology, #earthquake and sometimes #volcanic processes, related #hazards and risks, science communication…
I'm executive editor at TEKTONIKA https://twitter.com/WeAreTektonika (a DOA journal not yet on Mastodon), and advocate of #openscience, free #openaccess
Just moving from Twitter to Mastodon, and learning how to use it. Will keep the two accounts alive, at least for some time…
