A dude created a poll to allow everybody voting to continue banning Trump from the birdsite ⛔️. Will not RT his tweet, but you may easily find it on the birdsite: the account is from a guy named Elon M 🤔

Sedimentologika is officially open for submission - #DOAJ Diamond Open Access Journal #openscience #openaccess 

Hi! I’m a research scientist at the Geological Survey of Canada and adjunct professor at the University of British Columbia and the University of Victoria. I study #earthquakes and focus mostly on #SeismicRisk and #ActiveTectonics. I’m interested in #Paleoseismology #Neotectonics #Seismology #Geodesy and #SeismicHazard.

I’m also chair of the #AGU Hazards Equity Working Group, a Fast Reports editor at @weareseismica and a Building Equity & Capacity committee member for #SZ4D.

A magnitude Mw6.9 offshore south-central .

Mechanism and location suggest rupture on the shallow part of the close to the trench (on the very shallow dipping fault plane). However, modelled depth of ~19km, if true, seems little too deep given the closeness with the trench (USGS gives same depth and mechanism). This means that we cannot exclude a rupture on the steep fault plane within the oceanic plate.

Three other mysterious sketches. Now you know these are geographic maps to be completed. What are they showing ? 3/4

Yesterday I posted the sketch to the right asking "what is this?" Now you have the answer 👇🏼

It's from a 56 years old French book of exercises, to learn at primary school. Now an amazing . 1/4

I hope we can make this platform a better disaster communication tool than what we had on Twitter. Getting good information out during crises is one of the most important pieces of disaster science comms, & I think the length of these posts is going to be a big asset.

So this is my first post on Mastodon.

Part of my work as a volcanologist with the Italian National Institute of Geophysics and Volcanology (Istituto Nazionale di Geofisica e Vulcanologia, INGV) is the real-time surveillance of seismic and volcanic activity in the volcanic areas of Sicily. This is done in 8-hour shifts in the Operations Room of the INGV seat in Catania, the Osservatorio Etneo. This is me making a stupid face during my latest shift, on 5 November 2022.

Is there a #geotwitter equivalent here? For example, is it #geomastodon I wonder?

Well, well, happy to be there !

In an another world, a dude is trying to crash a 44 billion $ bird-shaped electric car 👇

What does this 👇 show?
Any idea ?
Hint: geography related

Answer to come…

Being editor of Tektonika (tektonika.online) I'm so happy to see that our friends from Seismica @weareseismica have just published their editorial paper "The launch of Seismica: a seismic shift in publishing" 👏

@jascha Induced seismicity is much less trendy in the #insurance industry than it was back when it was happening right under Oklahoma City.

But for those who don't have USGS #earthquake alerts set to M3.5... there are still a ton of induced earthquakes! Now mostly in West Texas.

Today’s #Texas M5.4 #earthquake (approximate location as a purple blob) in the context of nearby #reinjection wells and other recent #earthquakes on a map from Tung et al. (2020)

Dear #geotweeps,

We are very happy to announce that sedimentologika.org is online 🥳 you can check submission guidelines, reviewer guidelines and learn about the journal

Also submissions will be open starting 19th November 2022 🥳🎉 so get those manuscripts ready

RT @CopernicusEU: #DYK that parts of the Greek islands 🇬🇷 move (horizontally↔️) at a velocity of several mm per year?

You can monitor this phenomenon with the products of the @CopernicusLand European Ground Motion Service #EGMS

🆕The data can now be downloaded! More at land.copernicus.eu/news/the-eu

The #NASA #InSight team is holding a full science meeting this week at the Royal Astronomical Society (#RAS) in London. This might be one of the last team meetings during the mission given that the spacecraft is soon expected to run out of power and enter "dead bus" mode.
