A magnitude Mw6.9 #earthquake offshore south-central #Sumatra.
Mechanism and location suggest rupture on the shallow part of the #subduction #megathrust 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.

Larger map with epicenter of this event in red from USGS (both not yet on fediverse it seems)
Three other mysterious sketches. Now you know these are geographic maps to be completed. What are they showing ? 3/4
Answer tomorrow 😉
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 #cartography exercises, to learn #geography at primary school. Now an amazing #sciart. 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.
@janinekrippner Great !
Any preprint, on EarthArXiv or elsewhere ?

Is there a #geotwitter equivalent here? For example, is it #geomastodon I wonder?
@kwh Hi Ken. Happy to see you. Have a look to this toot and unfold the thread. https://mastodon.social/@allochthonous/109328830892142887
Good idea to use #geomastodon
Well, well, happy to be there !

Being editor of Tektonika (https://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.

RT @sedimentologika
Dear #geotweeps,
We are very happy to announce that http://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
@allochthonous Two main issues due to the distributed / federated system.
- Finding people (fellow researchers, medias, etc) to follow
- Same (and more complicated) for the general public and media people, by the way not really here yet.
No way to easily search for somebody knowing their name as on twitter (assuming they are publicly using it). Same for hashtags: as far as I understand I cannot explore the full fediverse for e.g. #earthquake
@allochthonous @rvawonk You may have a look to my Geo #scicom paper "Rapid collaborative knowledge building via Twitter after significant geohazard events"

Sorry for the self-promotion.

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
